Modify-Cut Plane
What it does
The Cut Plane tool calculates and draws a line at the intersection of two roof planes. This is particularly useful when constructing complex roof shapes one plane at a time and they need to be trimmed back to where the planes intersect.
🔧 How to use it
Select the Cut Plane button from the modify tools
Click on the first roof plane you want to find the intersection for
Click on the second roof plane
The software automatically calculates and inserts an orange line at the line of intersection
🛠 Example
When two roof planes intersect, the Cut Plane tool will mark their intersection with an orange line, as shown in the images below:
Top view: Two roof planes intersecting, with the orange line showing where they intersect as calculated by the software.
Right side view: The same intersection shown from a different angle.
💡 When to use this tool
This tool is most useful when:
Building complex roof shapes plane by plane
You need to trim planes back to their natural intersection points
Creating precise connections between different roof sections
