I’m confused, something changed in the last version. If I sketch a simple right angle, then add a slope line that doesn’t touch either end point, I cannot set the angle. What changed. What am I missing?
Hi,
Can you share a screenshot of this please?
Here’s two screenshots, second one is my workaround (have to add another random line. 
You can set angle between 2 lines only if one of their endpoints are in the same position. We don’t support not connecting line or “point-on-line” angle yet. Altought we are going to implement this in the near future, it’s a requested one and we also miss it during sketching
