Arc between two points with known radius?

[Zeke]

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.

Some extra work but in the end it worked fine. Thanks a lot!
