Partial detail cross section drawing:
When you have a 2D view, and you just need to see a partial cross section detail, at a depth, per exemple an internal groove or any detail.
This fonction is available per example in V5, you select the 3D depth in the 3D and draw a circle or curve in the 2D view, it can also to make more simple start with a 3D scetch of the 3D, so no need for selecting or drawing in the 2D.
Thanks,
Yan
