Step-by-step guide
Use reference planes to position a work plane for construction line purposes. Create a sketch of the roof profile on the reference plane.
- Open the project RF-Arch_Extrude Roofs_RVT2021.rvt. It opens in the 3D view.
- In the Project Browser, Floor Plans section, double-click Level 1 to open the view.
- Zoom in on the corridor between the main building and the garage.
- In the Architecture tab > Work Plane panel, click Ref Plane.
- Draw the reference plane across the corridor, verifying that the angle is perpendicular to the walls.
- Select <Click to name> and enter the name “Corridor”.
- Click Modify.
- In the View tab > Create panel, click Section.
- Draw a section line parallel to the reference plane.
- Click Modify.
Now, construct the roof by extrusion:
- In the Architecture tab > Build panel, expand Roof and click Roof by Extrusion.
- In the Work Plane dialog box, leave the default Pick a plane option selected.
- Click OK.
- In the view, click the reference plane drawn earlier.
- In the Go To View dialog box, select Section: Section 1.
- Click Open View.
- In the Roof Reference Level and Offset dialog box, select Level 2.
- Click OK.
- In the Modify | Create Extrusion Roof Profile, Work Plane panel, click Ref Plane.
- Draw three vertical reference planes, one on each side of the walls at 1'-6" off the wall, and one in the center.
To position the center reference line exactly between the walls:
- In the Annotate tab > Dimension panel, click Aligned.
- Click to add the dimensions from the first wall centerline, to the reference plane, and to the second wall centerline. Click again to place the dimension.
- Click the EQ control. The reference plane is now centered.
Draw an additional horizontal reference plane:
- In the Modify | Create Extrusion Roof Profile tab, click Ref Plane.
- Draw the plane just below the tops of the walls. The exact location is not important.
Now, sketch the roof profile:
- In the Modify | Create Extrusion Roof Profile tab > Draw panel, click Line.
- In the Options Bar, select Chain.
- Sketch the lines using the reference planes.
- Click Modify.
- In the Modify | Create Extrusion Roof Profile tab > Mode panel, click Finish Edit Mode.
The new roof is created.
