What it does
The Cut Line tool finds the intersection line between two roof planes and automatically inserts a cut line at that intersection point. This is particularly useful when constructing complex roof shapes plane by plane, where the roof planes need to be trimmed back to where they intersect.
🔧 How to use the Cut Line tool
Click the Cut Line button in the Modify Roof toolbar
Select the first roof plane you want to intersect
Select the second roof plane you want to intersect with the first
A cut line is automatically inserted at the intersection point
The roof planes will be trimmed back to where they meet
🛠 When to use Cut Line
The Cut Line tool is most useful when:
Building complex roof shapes one plane at a time
You need to precisely trim overlapping roof planes
Creating custom roof intersections that require exact alignment
Working with multi-level or stepped roof designs
💡 What to expect
After using the Cut Line tool, you'll see:
A visible cut line marking the intersection between the two planes
The roof planes automatically trimmed to the intersection point
Clean, precise edges where the planes meet
