Constructing an arc through a point tangent to two lines

Post by luggw1 » Sun Jan 19, 2020 6:31 pm

In the attached graphic, I want to construct an arc that passes through the intersection of the line and arc at point C and is tangent to the lines A and B. The line passing through point C is the bisector of lines A and B, so I know the center of the arc will lie on this line, but I can't seem to figure out how to construct this arc.

Can someone help me see what I'm missing as I'm reasonably certain there's a tool in QCAD that will help me with this.

Linux Mint 19.1
QCAD 3.23.0.0

Thanks

Thanks. I found these tools shortly after I posted this an then soon discovered the bug you mentioned. I'll download the latest version and give it a spin.
