Modify Roof > Change Pitch

🧾 What it does

The Change Pitch command allows you to modify the slope angle of one or more roof planes. When you change a plane's pitch, the roof geometry automatically updates to reflect the new angle.

🔧 How to use it

Go to Modify Roof > Change Pitch
Select one or more roof planes using either method:
- Click the tick mark in the corner of each plane, or
- Turn on plane hatching by selecting Tools > Show Planes, then click directly on the plane(s)
Right-click to confirm your plane selection
Enter the new pitch value for the selected planes
The roof geometry will automatically recalculate to accommodate the new pitch

After - Changing pitch on one plane:

🛠 Plane selection methods

Method	How to use
Tick mark selection	Click the small tick mark located in the corner of each roof plane (when planes are turned off)
Plane hatching/filled	Select Tools > Show Planes to display a visual pattern on all planes, then click directly on the plane surface

⚠️ Important considerations

Recommended for small changes: This command works best for minor pitch adjustments. Large pitch changes may cause the roof plane to fit incorrectly, and adjacent planes may not update as expected.

Adjacent plane behaviour: When you change one plane's pitch significantly, neighbouring roof planes may not automatically adjust in the way you expect. For major roof modifications, consider using other roof modification tools.
