Splitting with lines #57195

Open MTrim opened 4 months ago

MTrim commented 4 months ago

What is the bug or the crash?

Splitting polygons with lines doesn't work when the two different lines crosses in the middle of a polygon. It also depends on the chronological order. When you draw the first line accross the polgon it works. When you draw the shorter line first, the splitting doesn’t work https://www.loom.com/share/25d9a7d1a8484d19ac9407be1433655d?sid=8ed5f737-c55f-4c2d-9eaf-61ecee8be535 https://www.loom.com/share/5a5aa24d80284c97a5b52a6f46cc8152?sid=ea64ff4b-cb98-425e-94a7-bdbb2a6f9555

Steps to reproduce the issue

  1. Draw a polygon

  2. draw a line which crosses the polygon

  3. "Split with lines"

  4. select the layers => works

  5. Draw a polygon

  6. draw a line which ends inside the polygon
