When creating a line feature with snapping on, you can snap to intersect point of another feature. For example, in the following screen capture, I'm creating a two-point line, and it snaps to the intersecting line feature.
However, when I use geometric constraints, such as perpendicular, the snapping will no longer be working, see the screen shot below. I tried to adjust the tolerance but it's not the fault.
Same issue happens with right angle line:
Is there anything wrong with my approach?
Question for you - what release of ArcGIS Pro are you using?
3.3.0
