Ensure that Profile Members are Solids
The Profile Member must be a solid. Any Profile Member created from a 2D face (not a polyline) will automatically be a solid. However, it is highly recommended to use the Solid Inspector SketchUp extension (by ThomThom) to check for solid objects and to help fix any non-solid objects. This extension is available on the SketchUp Extension Warehouse.
Select a Solid Object to trim to
The object does NOT have to be Profile Member but it must be a solid.
As you hover the mouse, the object wil highlight to indicate that it is a valid solid.
Click the end of a Profile Member to Trim
As you hover the mouse over a Profile Member, it will become highlighted indicating that it is a valid solid.
Click on the end of a Profile Member to select it.
Continue clicking other Profile Members ends for trimming if desired.
Press ESC to reset the tool.
Congratulations! You just trimmed a Profile Member to a solid!
Note: Trims will be maintained even if the Profile Member attributes or path is edited.
