QUESTION

I need to create a bullnose verandah on the front of my building. How can this be done in Chief Architect? 

ANSWER

Chief Architect's roof tools are able to create a bullnose or curved roof for your house or verandah. In this article, we will walk through the steps for creating a bullnose verandah on the front of a simple home.

Creating the covered patio

1. Start by selecting Build> Wall> Straight Deck Railing from the menu.
   
   
   
2. Draw the outline of your verandah.
   
   
   
   
   
3. Select the deck room you just created and click the Open Object edit button.
   
   
   
4. Under the General panel, set the Room Type to Porch.
   
   
   
5. Under the Structure panel, change the Rough Ceiling to a height that is at least 12" (308mm) lower than the main house to avoid the roof merging together.
   
   
   In this example, the main structure has a Rough Ceiling of 14' (4,267mm) and the porch is 12' (3,658mm).
   
   
   
   
6. Under the Structure panel, check the box next to Roof Over This Room.
   
   
   
7. Check the box next to Use Soffit Surface for Ceiling
   
   
   
8. Click OK to close the Room Specification dialog.
   
   
   
9. Activate the Select Objects tool.
   
   
   
10. While holding down the Shift key on the keyboard, click on each railing to group-select all the railings and click the Open Object edit button to open the Deck Railing Specification dialog.
    
    
    
    
    
11. In the Deck Railing Specification dialog, select the Roof panel:
    
    
    
    
    • Set the Pitch to 6" in 12" (26.5°).
      
      
    • Check the box next to Upper Pitch.
      
      
    • Set the Upper Pitch to 1" in 12" (4.5°).
      
      
    • Set the In from Baseline distance to 18" (457mm).
      
      
    • Adjust the Overhang Length to any desired distance. In this example, 2" (51 mm) was used.
      
      
      
12. Click OK to close the Deck Railing Specification dialog.
    
    
    
13. Select Build> Roof> Build Roof from the menu to open the Build Roof dialog.
    
    
    
14. Check the box next to Build Roof Planes and, if necessary, uncheck Auto Rebuild Roofs.
    
    
    
15. Click OK to close the Build Roof dialog and build the roof.
    
    
    
16. Create a camera view to see the resulting roof.
    
    
    
    
    

Adding the bullnose

1. From the menu, select Build> Roof> Roof Plane .
   
   
   
2. Hold down the Shift key on the keyboard and group-select the lower roof planes over the porch.
   
   
   
   
   
3. Click the Open Object edit button to open the Roof Plane Specification dialog.
   
   
   
4. On the General panel, check the box next to Curved Roof and set the Angle at Eave to 45° and click OK to accept the change.
   
   
   
   
   
5. Open a camera view to see the resulting roof.
