Can anybody tell me how to draw a circle tangent to three lines or other circles?
I didn't know where to post this question - to Tips and tricks or to Wishes. Or to Wishes never to be...
Every time I need to do it I switch to AutoCAD and copy it back to AC.
So, you can do it in AutoCAD guys...

I think this option somehow got into ArchiCAD at some point.
Because when we had that original thread it was defiitely not possible. Two lines plus 1 point was possible, but 3 lines was not. I guess the developers justs made it possible at some point.

That's what I thought but then thought I must have missed something when I checked in version 12 and it worked there.
But 2004 must have been around version 9.

Anyway I'm glad it works now - just sad I'll probably never need it.

I also checked the Help file, it correctly states that you can define 3 tangent edges.

A parametric "Circle Tangent to 3 Circles" object.
Not yet implemented in ArchiCAD.

Adjust Blue Circles with Hotspots.
Hide Blue Circles.
Explode the Object.

Enjoy.
