Construction Documents and Details

BIM for Architecture, Engineering, and Construction Curriculum

Exercise 2.4.1: Creating Annotated Section Views

In this exercise, students will learn how to:

  • Create building sections showing an overview of the interaction between building elements.
  • Use a building section as a map referencing more detailed views.
  • Create wall sections to display typical wall assemblies and connections.

  • Create a building section to show the interaction of building elements along grid C. Display this section at 1/4" (1:48) scale and with a medium level of detail as illustrated in Figure 2.4.2a. 
  • Create a wall section for the south wall at grid C to show the wall assemblies and connection details. Crop this view to focus on this individual wall and its connection to floor, roof, and foundation elements. Display this section at 1/2" (1:24) scale and with a fine level of detail. 
  • Add annotations to the wall section to explain the wall construction and connection features, including text, tags, and detail components as illustrated in Figure 2.4.2b.
  • Place the building section and wall section views on a D-size sheet.

Exercise 2.4.2: Creating Details and Callouts

In this exercise, students will learn how to:

  • Use callouts to create detailed model views and adding annotations to these views.
  • Create drafting views to illustrate standard details and present views independent of the model.
  • Use callouts to reference drafting views.
  • Understand how the information presented a view tag is updated as views are placed on sheets.

  • Create a callout showing a detailed model view of the area at the center of the wall section created in Exercise 2.4.1 focusing on the wall-to-second floor connection. 
    • Set the view type to Detail.
    • Set the view scale to 1 ½” = 1’-0” (1:8).
  • Add detail components, adjust the filled regions, and add text notes explaining the essential framing elements and building details:
    • Use Nominal Cut Lumber-Section:6x12 (0.14 m x 0.29 m) for the rim beam.
    • Use Nominal Cut Lumber-Section:2x6 (0.04 m x 0.14 m) for the bottom plate of the second floor wall, and two of this component for the double top plate of the first floor walls.
    • Use Wood I Joist-Section:2 5/16x11 7/8 (0.06 m x 0.30 m) for the floor joists.
    • Adjust the cut profile for gypsum wall board layer of the wall elements on first and second floors as shown to eliminate the overlap with the intersecting floor element. Also adjust the cut profile of the finish layer of the floor assembly to remove the overlap with the wall framing layers. 
    • Add a detail component representing the molding at the base of the wall. Use Base Molding-Section and choose the 3/4”x 4” (0.02 m x 0.10 m) type.
    • Add 5 ½” (0.14 m) thick insulation to the upper and lower walls.
    • Add text notes notes as shown in Figure 2.4.4.

  • Create a new drafting view for a standard detail of a typical window header. 
    • Name this view Window Header - Typical.
    • Set the view scale to 3” = 1’-0” (1:4).
  • Import a CAD file (Manufacturer_Window_Head_Detail.dwg) containing the manufacturer’s standard window header detail. The file is located in the same folder as the exercise file. 
  • Add filled regions, detail compoments, and annotations to develop the full detail as shown in Figure 2.4.5.
      • Create filled regions representing the layers of the wall assembly: 
        • 1/2 inch (13 mm) gypsum wall board
        • 5 1/2 inch (140 mm) stud framing
        • 1/2 inch (13 mm) plywood
        • 7/8 inch (22 mm) stucco

      • Add detail components:
        • Use Nominal Cut Lumber-Section:6x8 (0.14 m x 0.19 m) for the typical window header.
        • Use Common Wood Nails Side:10 penny for the nails at the window flange.

    • Add a fill region to represent caulking between the window and the gypsum wall board.
    • Edit the fill region for the gypsum wall board to wrap around the header component and into window opening to meet caulking.
  • Add text notes similar to those shown in Figure 2.4.5.
  • Add Break Line components at top and bottom of the detail.
  • Place on sheet S3 – Wall Details.
  • Add a callout to the Wall Section A view to reference the new drafting view.  Enable the Reference other view option, and choose Drafting View: Window Header – Typical from the list.
  • Place both of these details on a Sheet S3 – Wall Details and observe how the view tags update with the sheet and view numbers referencing the placement location.
