What version of LibreCAD?, in what OS?

For me it works as following (LibreCAD 2.1.3 on Linux Debian Sid):

draw a horizontal line (the plane)

draw a tangential cicle to that line (the first circle, here I miss a

tangential radius command)

click on tangential 2 circles radius, select the circle and the line as

first and second circles and write the radius size in the box.

Yes, I know it is not obvious to select the line when the command tells

you it needs a circle :)
