To draw a circle tangent to 3 equal sized circles (this ones for you Husky )
1. Draw 3 circles (same radius) with centers at any given coordinate points.
2. Set up ' layer ' construction and draw polyline (A) to connect all the centers.
3. Draw a line (B) > using Relative Angle ( LR) set to 90 and at an arbitrary length (say e.g. 100) and 'snap' to the center/middle of one line to produce a line perpendicular to it (90 degree right angle).
4. Repeat for the other line (C), the intersection of these two lines provides the center point (D) for the 4th circle.
5. From any circle draw a line (E) from its center to the intersection, this will be the radius for the 4th circle.
Job done.

Hey everybody - just an update on this:
The new version of QCAD pro (3.2.0) has a new circle tool set which provides a perfect solution on this.
Two or three clicks .... and done!!!
You have to test it by yourself - absolute amazing!!!!

Yes its brilliant, what would be interesting is if it were possible to select all the solutions offered (in one go)Husky wrote:You have to test it by yourself - absolute amazing!!!!
@Andrew - would this be possible to add in an option for this ? it would make for very interesting pattern making
