>>Hi Martin, I'm glad that you got it solved. I will look into adding this case into the circle and arc tangent commands.

That would be nice if you can do it and definitly appreciated by me - not because I perform this particular manoeuvre on a daily basis, but it would be one less interruption to hamper workflow when the need arises.

Well apart from this one case, I must say that I tried quite a few different tangent intersection scenarios and have come away very impressed with the logic built in to MoI and its ability to find the right solution. Most software seems to either give a null result or insist on jumping to the wrong side of the arc when doing one of the more unusual kinds of blend.

Thanks to all for helping.
