QUESTION
How do I create and generate framing for aparapet wall that has an arch?
ANSWER
You can create an arched parapet wall by building a new 2nd floor, adjusting the height and materials as needed, then modifying the front parapet wall using a roof plane.
Begin by opening the plan in which you would like to create an arched parapet wall. In this example, a simple 30' x 40' rectangular structure with a basic foundation will be used.
To create parapet walls
- The roof area with parapet walls will be created using an additional floor, so select Build> Floor> Build New Floor
from the menu.
- In the New Floor dialog, choose Derive new 2nd floor plan from the 1st floor plan option and click OK
- On the Structure panel of the 2nd Floor Defaults dialog, which opens next:

- Set the Rough Ceiling value to equal the height you would like your parapet walls to be.
In this example, a value of 36" is specified.
- Remove the checks from Roof Over This Room and Flat Ceiling Over This Room.
- Click the Edit button next to Floor Finish to open the Floor Finish Definition dialog.

-
Select the topmost layer, click in the Texture box, select an appropriate flat roofing material, then click OK.
-
Add and/or remove any additional layers, as desired.
-
Click OK.
- Next, access the Moldings panel and click on the Delete button to remove the base molding from the 2nd floor.

- Click OK, then create a Camera
view to see the results so far.

To add an arch to a parapet wall
- Using the Select Objects
tool, click on the 2nd floor parapet wall that will have an arch, then click the Open Object
edit button.
- On the Structure panel of the Wall Specification dialog that displays, select the Balloon Through Ceiling Above option under the Ceiling Platform heading, then click OK.

- Select Build> Roof> Roof Plane
from the menu and perform the following:
- Left-click and drag to create the roof plane's baseline spanning both the interior and exterior of the parapet wall.

- Once the baseline has been created, move the mouse to the opposite side of the structure and click where you would like the roof plane to stop at.

- Adjust the left and right edges of the roof plane, as needed. The left edge of the roof plane will be where the arch starts, while the right edge will be where the arch stops.
In this example, we created a roof plane that is 24' in length and centered on the structure.
