Introduction
The information you need to create each of these drawings is given in these instructions. Be aware that some of the information you may need to draft a particular drawing or detail may be given in desсrіptions of other parts of the building. Therefore, you should read all the instructions before you actually begin drawing. Your job in this project is to use your drafting skills to clearly and completely reveal—in the seven drawings—all the verbal information presented here about the building’s construction.
You won’t need to print or plot your drawing. When you’re finished with the project, you’ll submit your electronic drawings for grading.
Your drawings will be for a two-story storage building with a flat roof. The roof is sloped so rainwater drains toward the roof drain. The exterior walls of the building are 24″ higher than the roof’s surface. The only opening into the building you’ll be dealing with is a large sliding glass door on the first floor. The drawings will be drafted according to the instructions listed here.
Before starting your project, download the Structural Drafting Project AutoCAD Files to complete this project.
General Setup
Use the AutoCAD settings listed here when specifying your units and style.
Unit. Set the architectural units to 64ths. Use surveyor’s units for the system of angle measurement.
Style. Change your Standard style to use ROMANS font. Use 0.00 as text height and 1.00 as text width. Keep the remaining style settings as per the defaults.
Use the information listed here when setting up your layers.
One of the best habits you can develop when using AutoCAD is that of carefully defining your layers. The layer names should be desсrіptive, and the color and linetype of all your entities should be assigned by layer. Colors are used with plot styles to create the desired line thicknesses (weights). Thus, if one of your layers is named ″Concrete″ and assigned the color yellow, any entity drawn on that layer will be yellow. If you want to make all Concrete entities magenta, you can simply change the color in the Layer Control dialogue box to magenta. On the other hand, if you’ve drawn a circle on the magenta Concrete layer but have assigned that circle the color blue, to change the circle to a different color, you must actually change the color property of the circle to Bylayer.
Developing the habit of assigning color and linetype by layer and using only desсrіptive layer names will help you keep the elements of your drawings standard. In addition, if you decide to exchange drawing files with drafters in other firms, the drafters will be able to easily change layer colors for plotting with their own plotters. Exchanging drawing files in this way is a common practice. Some government bureaus, for instance, may require copies of your electronic files when issuing building, sewer, or electrical permits.
The layers to use with the foundation plan (Sheet 1) of this project will be given. For the remainder of the drawings, you must create your own layers using the above recommendations. Assign colors to the layers using the guidelines listed in the Layer Lineweights and Thicknesses table.
Layer Lineweights and Thicknesses
Layer color Linetype Use
Magenta Thin Small details, hidden lines, hatches, and small text
White Medium thin Object lines and normal text
Blue Medium thick Outlines that need to be emphasized and large text
Create all your drawings using actual measurements. For most of these drawings, you’ll leave them in their actual measurements. A viewport will then be placed in the Layout tab for each drawing at the proper scaling factor for plotting. It’s best to work using the actual measurements so it′s easier to make any changes to the drawing later. Not all of the drawings in this project will have the same scale for plotting, even though they’ll all be drawn using actual measurements.
The first step is to set up your Layout tab (the Paper space) and title block. Many companies have their own standard title block and template that you use to create your drawings. To set up your title block, follow these steps:
Open the Project Title Block.dwt file on your computer. A new drawing should open in AutoCAD using this template.
Click on the Layout 1 tab. Now double click on the title block. This will open the Edit Block Definition window.
Select the Project Title Block Student, and choose OK. This will open the Block Editor.
Select the MText tool.
Create text for your name and student ID in the ″Firm Name and Address″ box, using a text height of 3⁄32″. Select the Close Block Editor button when you′re finished and choose Save Changes. This will bring you back to your drawing.
By using Mtext within the title block drawing for this, the information can′t be edited when inserted into another drawing.
For any information that needs to be edited, you need to set up attributes. These contain the information that will change from drawing to drawing.
Go to the Insert menu, then Define Attributes. This opens the Define Attributes Window.
At the top right-hand side is a box called Attribute. The Tag field is the tag that will be displayed on the drawing; it acts as a placeholder until the attribute is edited and the required text is entered. Tag names can′t have spaces or characters in them. Try to use appropriate tag names, such as ProjName for Project Name.
The Prompt field is the prompt text that will be displayed when editing attributes. These fields can use spaces, so can provide more detail on what information is required. For example, Project Name would be the Prompt text for an attribute with the tag ProjName.
Default is the default text shown in the attribute. It′s useful to put a default for at least one attribute, so there′s an editable attribute shown on the title block when it′s inserted.
Set up attributes for the following information within the title block, using a text height of 3⁄32″
In the Project Name and Address box, set up a multiple line attribute for the project name and address by checking the Multiple Lines box.
In the Drawing Title box, set up an attribute for the drawing title.
In the Project Reference box, set up an attribute for the project reference. For this project, this will be the sheet number.
In the Design Date box, set up an attribute for the date of the drawing.
In the Scale box, set up an attribute for the scale of the drawing.
In the Revision box, set up an attribute for the revision number of the drawing. Insert a Default value of –.
You don′t need to enter any information under the general notes in this drawing; you′ll set that up in your site layout drawing.
Choose Close Block Editor on the menu at the top of the screen and choose to save the changes to the title block.
Update the title block details by double-clicking on the dash (–) in the revision box. This will bring up the Enhanced Attribute Editor window.
If you can′t see the attributes within the title block, use the ATTSYNC command, which should now display the dash (–) in the Revision box.
For the project name and address, enter Two-Story Storage Building, Superior Contractors Ltd, Scranton, PA, 18515.
For the Project Ref, enter 212030 Sheet 1 of 7. This assumes that a project will have a unique project number (212030) and the number of drawing sheets.
Enter the date you start the drawing in the Design Date field.
Leave the Drawing Title and Scale fields for now. Update this when the titles and scales for the drawing have been set.
Set the Revision field to 0. This is updated every time there′s a revision to the drawing.
Save your drawing as Building.dwg. Now that your title block is ready, you can copy the Layout tab to create new sheets for the different drawings in this project.
Drafting the First Floor Framing Plan (Sheet 1)
Draft the framing plan at actual size. This is the ground floor (the first floor of the building).
The dimensions of the building are given to the center of the structural steel columns. All of the columns in the building are W-shapes with the designation of W12 × 152. For the dimensions associated with this designation, consult the AISC Shapes Database spreadsheet. Create a layer named W12 × 152 with the color white and a continuous linetype.
The building has 20 steel columns—14 spaced around the building’s perimeter and six within the interior. Arrange these W-shape columns on the foundation plan in four evenly spaced rows of five beams each. The distance between the center of the beams in adjacent rows is 18′-0″. The distance between the centers of adjacent beams in each column is also 18′-0″. The overall dimensions of the building are therefore 72′-0″ × 54′-0″ (L × W).
When laid out on the foundation plan, the steel columns are shown with their flanges running horizontally. In other words, when you view the plan with the drafting sheet turned so that its long edge is on the bottom, the steel columns will look like an “I.”
Create a layer called Footing, with a white color and a continuous linetype. Draw the footings on this layer. The dimensions of the concrete footings placed under all the steel columns are 32 × 32 × 16 (L × W × D). The steel columns are centered over these footings.
In between adjacent steel columns are W12 × 40 steel girders. There are 31 of these girders. The girders support the building’s second floor. Again, consult the AISC Shapes Database spreadsheet for the dimensions of this structural steel shape. Draw the girders on a layer called Girders, with a blue color and a continuous linetype.
Create a layer called C9 × 20, with a white color and a continuous linetype. Running horizontally between adjacent girders are 24 steel channel beams. There are two channel beams in each 18′-0″ bay, and they’re spaced 6′-0″ apart. The beam designation is C9 × 20, and its dimensions can be found in the AISC Shapes Database spreadsheet. The channel beams are aligned so they′re flush with the top of the girder and form a C shape. A section 3 7⁄8″ long is cut out from the end of the channel to make an allowance for the flange of the girder. There’s a 1″ gap from the web of the girder to the end of the channel, and between the girder flange and the cut-out section of the channel.
Each channel beam is bolted to the girder with a 1⁄2″-thick angle. Each leg of the angle is 4″, and the angle is 6″ wide. Two angles are used for each channel beam, one at either end of the channel. The angle is bolted to the web of the channel using two 5/8″ &emty; bolts that are 3″ long. The center of each bolt is positioned 11⁄2″ away from the vertical edge of the angle and 13⁄4″ away from the horizontal edge of the angle. Two more bolts with the same dimensions and locations fasten the other leg of the angle to the web of the girder.
Create a dimensions layer called Text-Med, with a white color and a continuous linetype. Put all your dimensions and text on this layer. Add callouts to every girder and channel on the Text-Med layer (for example, girders should be called out as W12 × 40). Also add notes with leaders to call out the columns and footing sizes.
Create a layer called Centerlines, color white and using the center linetype. Instead of extension lines, draw centerlines up from the five W-shapes at the top of your drawing. From the four W-shapes on the left of the drawing, again draw centerlines instead of extension lines. Mark off with a bubble each of the nine centerlines you’ve extended out from the structure. At the top of the drawing, number the bubbles, from left to right, 1 through 5. At the left of the drawing, letter the bubbles, from top to bottom, A through E.
Give the dimensions for the width and depth of the bays. For these dimensions, place your dimension lines between the perimeter of the structure and the numbered and lettered bubbles. Past the bubbles, place another set of dimension lines to show the width and depth of the entire structure.
Show two cutting plane symbols.
The first section’s letter is A, the sheet that locates the section is 1, and the sheet where the drawing of the section is shown is 3. Make the circle for the symbol and the text an appropriate height. Place the symbol so that it points to the top of your drawing and place it between rows B and C. Show the section line cutting through the entire building.
The letter for the second section is B, the sheet that locates the section is 1, and the sheet where the drawing of the section is shown is 4. Copy the symbols you created for Section A, editing appropriately. Place the new symbol so that it points to the left and place it between columns 2 and 3. Show the section line cutting through the entire building.
Place a north arrow at the bottom of your drawing so that it indicates the long side of the building (which will be at the top of the sheet) as the north elevation. Angle the north arrow slightly at a direction of N12°14′0″E.
Next, go to the Layout tab. The drawing would be plotted at a scale that will result in a finished 24″ × 36″ landscape plot, so the viewport needs adjusting to the correct scale to make the drawing fit. Select the viewport from Paper Space and change the scale so all the elements are shown. Be sure to lock the viewport so the scale won’t accidentally change as you work on the drawing. From the Layout tab, double check that your text, dimensions, and linetypes are readable at this scale, and adjust if necessary.
Next to the north arrow, create the underlined text FIRST FLOOR FRAMING PLAN. Put the text on layer Text-Large, with a blue color and a continuous linetype.
Title this drawing FIRST FLOOR FRAMING PLAN and fill in the scale.
Drafting the South Elevation (Sheet 2)
Some parts of the elevation can’t be accurately described without examining the building’s section. Use the information listed here, then either calculate the additional information you need or draw the building section first to reveal the information you’re missing.
The finished grade elevation is 292.90, the first-floor elevation is 293.90, and the second-floor elevation is 305.19. The distance from the top of the footings to the finish grade is 4′-0″.
A 4 × 2 keyway (longitudinal groove) is centered at the top of each footing. Centered over each footing is a concrete pier that’s 16″ wide on each side and 4′-0″ tall. At the 4′-0″ height, the concrete angles away from the piers at the 45° angle for a vertical and horizontal distance of 6″. This height marks the bottom of the 6″ poured-in-place concrete slab making up the first floor. This concrete slab rests on an 8″ thick layer of compacted sand, which rests on earth.
The piers at the four corners of the building are different from the other piers. These corner piers have a height of only 2′-6″ before the concrete begins to angle away. The concrete angles away from the pier at a 45° angle for a vertical and horizontal distance of 2′-0″.
A 4″ drain is set around the outside of the building, with 3″ clear above the footings to the drain and 3″ clear from the piers to the drain.
The rebar in the bottom and along the sides of the footings is #4 rebar (1⁄2″ diameter) at 8″ OC both ways. The rebar is located 3.5″ from the face of the footing on each edge. The rebar near the bottom of the footing extends up the sides of the footing by 6″. The callout for the rebar is #4 ∅ @ 8″ O.C. BOTH WAYS.
Vertical and horizontal rebar is placed in the pier. Notice how the rebar from the pier extends down into the footing—use the same detail here but space the horizontal rebar at 8″ centers. The overlap detail at the bottom of the rebar is 2″ long. This rebar is #6 rebar (3⁄4″ diameter) at 8″ OC. Add a callout for this rebar.
A steel sheet is centered over each footing at the top of the first-floor concrete slab. The sheet is 14 × 14 × 1⁄2. The W12 × 152 steel column is welded to the sheet. The weld is a 1⁄2″ fillet weld. The weld symbol—as it should also appear in a detail of the joint on your drawing—consists of an arrow, two triangular “fillets,” and the size designation. Note that the triangular shape appears on both sides of the horizontal line. The use of two triangles on the symbol indicates that the weld is made on the arrow side of the joint as well as on the opposite side. If the required weld were only on the arrow side of the joint, the triangle would appear on only the bottom part of the horizontal line.
The sheets are bolted to the concrete slab with two anchor bolts that are each 11⁄2″ diameter and 18″ long. The bolts project out of the concrete slab 31⁄2″. The bottom 4″ segment of the bolt is bent horizontal, pointing toward the center of the building. The center of the bolts are 31⁄2″ from the edge of the steel sheet. The callout for these bolts is (2) 1-1⁄2″ ∅ × 18″ UNC 2A BOLTS W/3-1⁄2″ PROJ. @ EA. COL.
Metal siding (4″ box rib) is installed vertically on both the outside and the inside of the building. The shape and dimensions of the siding are shown in Figure 1. The metal is 3⁄32″ thick.
An image of a line made of half hexagons with dimensions, to represent metal siding panels.FIGURE 1—The shape and dimensions of the box rib siding.
The clear distance from the first floor to the bottom of the first-floor ceiling is 10′. The clear distance from the second floor to the bottom of the second-floor ceiling is 8′. The distance from the first floor to the top of the building is 22′-7″.
A supply entrance door to the lower floor is on the building’s south side. It’s a sliding glass door centered between columns 3 and 4. The rough opening for the door is 12′ wide and 8′ high. Above the rough openings is a steel W-shape header, W10 × 54. The header is placed so that the flanges are horizontal and the web is vertical. The height of the header is 101⁄8″.
For your drawing of the building’s south elevation, label only the items listed here, complete with their various size desсrіptions (such as the item’s dimensions and so forth):
Door header
6′ × 8′ sliding door (the word sliding can be abbreviated SLD)
Metal siding
Reinforcement, bolts, and weld
Elevations of finish grade, first floor, and second floor (the word elevation can be abbreviated ELEV)
In your drawing, remember to show the concrete footings, the steel columns, and the southern roofline as hidden lines. Use texture lines to show the metal siding in small patches only. Filling in the entire surface with texture lines on a drawing is unnecessary and can be visually distracting. Doing so may also conceal features that are shown only in that particular view.
Show a line for the finish grade. Show a patch of earth below the finish grade as per Figure 2.
An image of a line with a hatched area underneath to indicate the ground level of the earth, with instructions on how to add a hatched area. FIGURE 2—An example of the finished grade and earth hatching.
On the title block in the Layout tab, change the title of this drawing to SOUTH ELEVATION. Fill in the scale on the title block. Change the Sheet number to 2. Double check that all text, hatches, and linetypes are readable at the scale you′ve chosen and adjust if necessary.
Drafting Section A (Sheet 3)
You’ll use the information given here extensively when drawing the building’s details. For drawing the section, however, you’ll be concerned primarily with the accuracy of the overall dimensions. A section shows an overall view of how the building is constructed. Sometimes it’s impossible to convey all the information about a building’s construction in a full section. Some of the smaller features may need to be omitted for clarity. In your drawing of Section A, you may choose which features to omit. The dimensions of these features, however, need to be taken into account to draw an accurate overall view. You may find it helpful to draft some or all of the details first, before drawing the section.
The second floor is made up of a composite steel deck system similar to one shown in this drawing. Composite steel decks have a steel sheet that′s bolted to the floor beams, then has reinforcement laid on it. Concrete is then poured over the deck to create a floor. The rebar within the poured-in-place concrete slab is #4 rebar (1⁄2″ diameter) at 12″ OC both ways and the concrete slab is 6″ thick. The steel decking has the same dimensions as the building’s steel siding.
Installed below the C9 × 20 beams are 1⁄2″ ceiling tiles.
The roof is also made up of a steel deck system. The 6″ thick concrete slab, however, slopes toward the roof drain at a rate of 1⁄8″ every 1′-0″. Note that this slope will be from three directions. A roof drain is positioned between columns 2 and 3 and between rows A and B. The drain is similar to the one shown in Figure 3 and connects via a 3″ PVC pipe to a 3″ diameter downspout down the exterior of the building.
Estimate the dimensions of the roof drain, and include the note ROOF DRAIN, SEE DETAILS on your drawing.
An image of a drawing of a roof showing a drain with a membrane and grate within the deck. FIGURE 3—An example of a typical roof drain.
Welded wire fabric is part of the steel deck system for the roof. The wires are #12 gage, and the spacing is 6″ on center. Figure 4 shows how welded wire fabric is indicated on a drawing. There’s a 3″ clearance from the edge of the wire fabric to the wall and a 3″ clearance from the wire fabric to the bottom of the steel deck system.
An image of a line with X’s spaced at regular intervals. Figure 4—The linetype for indicating welded wire mesh within a drawing. The x’s are located at the same center spacing of the mesh.
The exterior walls of the building extend beyond the roof by 24″, creating a short wall around the roof area. The top of the wall is capped with a 14″ wide steel sheet welded to the top end of the steel column. The weld is a 1⁄2″ fillet weld. The 14″ wide steel sheet is 11⁄2″ thick at its exterior edge and slopes toward the building interior at a rate of 1⁄4″ drop for every 1′-0″ of run.
Flashing is installed over the sheet and is sloped toward the building interior. The flashing is 3⁄32″ thick and extends down the side of the walls approximately 8″.
Several details need to be circled on this view. The details will be shown at a larger scale on other drafting sheets later in the project. When indicating the details, circle the area to be shown and attach a “detail bubble”—similar to the “cutting plane bubble” but without the arrow (see Figure 5.)
The first detail is the Roof Detail at the building’s easternmost side. Letter this Detail C and show it on Sheet 5.
The next detail is the second-floor connection at B4. Letter this Detail D and show it on Sheet 6.
The next detail is the footing and first-floor connection at the building’s easternmost side. Letter this Detail E and show it on Sheet 7.
An image of a roof deck drain with a section circled and a circle with the letter A on the top half and the number 3 on the bottom half.Figure 5—A typical detail bubble for assigning a letter designation and indicating where the detail can be found.
Label the elevations as well as the vertical dimensions. On the title block in the Layout tab, change the title of this drawing to SECTION A. Fill in the scale on the title block. Change the Sheet number to 3. Double-check that all text, hatches, and linetypes are readable at the scale you′ve chosen and adjust if necessary.
Drafting Section B (Sheet 4)
Much of the work you did to produce Section A can be used again for Section B. Keep in mind, however, that several things will be different. For example, you’ll be seeing the cross-section of the channel beam instead of the flat side of the beam as shown in Section A.
A detail is circled on this view. Again, use a detail bubble. The detail shows how one of the C9 × 20 beams connects to a girder. Letter this Detail F and show it on Sheet 6. Label the elevations as well as the vertical dimensions.
On the title block in the Layout tab, change the title of this drawing to SECTION B. Fill in the scale on the title block. Change the Sheet number to 4. Double check that all text, hatches, and linetypes are readable at the scale you′ve chosen and adjust if necessary.
Drafting Details C, C1, and C2 (Sheet 5)
This drawing will contain some of the details indicated on the section drawings (sheets 3 and 4). You′ll need to refer to these drawings in order to complete the details. The best way to start is to draw each detail at the actual size in the Model space.
Sheet 5 contains three details. The first detail shows the top of the wall and details the connection of the roof to the outside wall. This detail is called the Roof Detail. On this detail you’ll indicate two areas that will have further details:
The first of these is the Cap Detail for the top of the wall, which you should label C1.
The second additional detail is the Connection Detail between the roof beams and the exterior wall columns, which you should label C2.
For the Roof Detail, labeled C, indicate the items listed here, along with their size desсrіptions:
The composite steel roof deck sloped 1⁄8″ every 1′-0″ toward the roof drain. This includes the poured-in-place concrete slab (6″ thick), the reinforcement, and the steel decking.

Clearance of the welded wire fabric from the top of the beam
Next, go to the Layout tab. Create 3 viewports within the Paper space for the three details. Show one detail in each viewport, choosing an appropriate scale. Note that Details C1 and C2 require larger scales than Detail C, and C1 and C2 may not be the same scale.
On Details C1 and C2, use breaklines to isolate just the detail being shown. Place a title under each detail (for example, Connection Detail C2) and the scale of the detail.
On the title block in the Layout tab, change the title of this drawing to ROOF DETAILS. Change the scale on the title block to VARIES. Change the Sheet number to 5. Double check that all text, hatches, and linetypes are readable at the scales you′ve chosen and adjust if necessary.
Drafting Connection Details D, D1, F, and F1 (Sheet 6)
This drawing will contain the remainder of the details indicated on the section drawings (Sheets 3 and 4). Refer to these drawings in order to complete the details. As you did for Sheet 5, draw each detail at actual size in the Model space.
Sheet 6 displays four connection details. Two of these details (lettered D and F) contain the connections enlarged in Details D1 and F1.
Connection Detail D shows the connection at B4 from Sheet 3. Indicate on it the area for Detail D1, which will show the connection of the beams to the girder.
Connection Detail F shows the connection of the C9 × 20 beam from Sheet 4. On this detail, indicate the area for Detail F1, which will show the connection of the channel to the girder.
For Connection Detail D, indicate the items listed here, along with their size desсrіptions:

Girder
Clearance of the rebar from the girder
The angle
Width of the angle
Bolts
Placement of the bolts
Next, go to the Layout tab. Create 4 viewports within the Paper space for the four details. Show one detail in each viewport, choosing an appropriate scale. Note that Details D1 and F2 will require larger scales than Details D and F, and that they may not be the same scale.
On Details D1 and F1, use breaklines to isolate just the detail being shown. Place a title under each detail (for example, Connection Detail F1) and the scale of the detail.
On the title block in the Layout tab, change the title of this drawing to CONNECTION DETAILS. Change the scale on the title block to VARIES. Change the sheet number to 6. Double check that all text, hatches, and linetypes are readable at the scales you′ve chosen and adjust if necessary.
Drafting Foundation Details E and E1 (Sheet 7)
This drawing will show the foundation details and how the foundation connects to the first floor. Like the other detail drawings, you′ll need to refer to the sections and create a multi-viewport drawing. Draw these details at actual size in the Model space.
Sheet 7 displays two details: a foundation detail and a connection detail. The foundation detail, lettered E, shows the outside footing, pier, and column connection at the first floor. On this detail, indicate the area for Detail E1, which will show the connection between the steel column to the first floor.
For Foundation Detail E, indicate the items listed here, along with their size desсrіptions:

Next, go to the Layout tab. Create 2 viewports within the Paper space for the two details. Show one detail in each viewport, choosing an appropriate scale. Note that Detail E1 may need a different scale than Detail E.
On Detail E1, use breaklines to isolate just the detail being shown. Place a title under each detail (for example, Connection Detail E1) and the scale of the detail.
On the title block in the Layout tab, change the title of this drawing to FOUNDATION DETAILS. Change the scale on the title block to VARIES. Change the Sheet number to 7. Double-check that all text, hatches, and linetypes are readable at the scales you′ve chosen and adjust if necessary.
Inspecting Your Work
Before sending your drawings for grading, examine them for any errors. Make sure your name and student number appear on every drawing, and in the filename. As part of your inspection, consider the following points:
Check for correct shape, size, and placement of entities. Exact placement can be confirmed by checking the coordinates of all lines, points, and arcs.
Check that the entities are on the right layers.
Check to ensure your blocks are the correct size, if you′ve used any blocks.
Use the ERASE command to delete any unwanted marks.
Make sure your name and student number appear on the drawing title blocks and in the filename (John Smith Structural Sheet 1.dwg).
When you feel confident that your work is complete, submit your work. Send in this material as soon as you complete the project. Don’t wait until your work on the next project is finished.
