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
Before:
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.
💡 Tips
Turn on plane hatching (Tools > Show Planes) to make plane selection easier, especially when working with complex roof geometries.
