Hi Michael, many thanks for your kind response! I have used a few 3D packages over the years and I can say that what you have achieved with MoI is fantastic! The user experience of MoI is an absolute pleasure! There is no other software with such intuitive ease of use and functionality. I have never used any other software, 3D or 2D that has as impressive snaps (smart guides) as MoI does! You should feel incredibly proud for what you have accomplished.

Yeah, I am familiar with the distance constraint (another great feature!), although I would prefer the line that I am moving to remain at the same angle and 'snap' into the corner on the two edges. I do appreciate that this function may not be available as I cannot think of any other software that is able to do this. I was just hoping that there may be someone able to help with an alternative solution.

Many thanks
