You asked for a tangent arc with radius between line A and arc B. Take a look at the more elaborated version of my file. Rotating a tangent around it's tangent point it will become non-tangent.

This is where the only snap that works, as I envison, is (on-entity), and it gets me oh so close, but not exact. Then I want to snap it to tangent to the straight line that is parallel to the front line. It allows me to select the intial Arc (3/4' radius in dxf) and displays the appropriate circle based on the value i gave it in the dialogue box (3). I want to know about, what I have found to be the closest thing to what I am used to, (Tangent, Point, Radius) is the right direction for me. QCAD is working different here in this regards and I understand the Tangential snap is NOT designed for this. One is made using the fillet command on the bumped out portion (easy) and the other is an arc that is drawn using snaps of tangent to tangent. In the attached dxf file of a traditional countertop drawing, I am trying to draw two arcs that connect tangentially. I use a CAD/CAM program called DDX Easystone in addition to QCAD, and in their software, it has limited cad tools but the ones it does have are simple and powerful at the same time.
