Arc between two points with known radius?

Postby Zeke » Thu Sep 23, 2010 1:53 pm

I have two intersection I want to connect with an arc. I know the radius of the arc but not the center of the arc. I can do this in other cad-programs but couldn't find this function in Qcad. Any suggestions?

Arc that connects P1 and P2 with radius R:

- Construct two circles with centers P1 and P2 and radius R.
- The two intersection points of the two circles give you the two possible center points of the arc.
