QUESTION

When I set the Pitch for the Roof in the Build Roof dialog, it only lets me set one pitch. How do I tell the program to build a higher, or lower, pitched roof over part of my design? 

ANSWER

The Pitch for each individual wall in your plan can be specified on the Roof tab of its Wall Specification dialog. Most of the pitches for your roof are likely the same, with only a few being different, so this is the pitch you'll want to use in the Build Roof dialog. 

To set the overall pitch

1. Within your plan, select Build> Roof> Build Roof .
   
   
   
2. On the Roof panel, set the overall Pitch for your plan that most of your roof planes need to be.
   
   
   
   For the purposes of our example, we will set this Pitch to 12" for an Imperial plan, or 45° in a Metric plan.
   
   
   
3. Click OK to apply this change.

Once you've set your overall pitch for the roof planes, you're ready to go around on a wall by wall basis and change the necessary walls that you don't want to follow the default setting. 

To adjust the pitch over a single wall

1. Using the Select Objects  tool, click on the wall which has a higher, or lower, pitch than what you set in the Build Roof dialog, then click on the Open Object  edit button.
   
   
   
2. Select the Roof panel, and put in the desired pitch for the roof plane that will build over this wall.
   
   
   
   For the purposes of this example, we will set the Lower pitch to 6" in an Imperial plan, or 26.5° in a Metric plan, and make sure to delete the (D), which stands for Default. As long as this D in parenthesis is still in the field, it will reset back to the default value.
   
   
   
3. Click OK to apply the change.
   
   If you have Auto Rebuild Roofs enabled in your Build Roof dialog, the roof will automatically update to reflect this change.
   
   
   
4. Repeat this process for any other walls in your plan which need to have a pitch that varies from the default set in the Build Roof dialog.

In some cases, such as in a gull wing or roof porch area, you may need to be able to set both an upper and a lower pitch for the roof

 

To set an upper and lower pitch

1. As described in the steps above, use the Select Objects tool, click on the wall which has a higher, or lower, pitch than what you set in the Build Roof dialog, then click on the Open Object edit button.
   
   
   
2. Select the Roof panel, and put in the desired Lower Pitch for the roof plan that will build over this wall or railing.
   
   
   
3. Then place a checkmark next to the Upper Pitch, and put in the appropriate pitch and in from Baseline values.
   
   
   
   
   
4. Click OK to apply the change.
   
   If you have Auto Rebuild Roofs enabled in your Build Roof dialog, the roof will automatically update to reflect this change.
   
   
   
5. Repeat this process for any other walls in your plan which need to  have a pitch that varies from the default set in the Build Roof dialog.
