I installed it on a 32 bit computer, and it works perfectly. I appreciate the help - I will re-install on my current computer and try again.

It is fantastic BTW - thank you TIG!

Baz,

I have three lines grouped, so it looks like it may have hidden stuff, but I checked. Do you think it might be windows 64 bit that is the problem?

TIG,

I am very excited to use this plugin, but sadly, I seem to lack the skill - I have sketchup 8 pro, I have made 2 groups of edges and named them 'path' and 'profile', it seems to be working giving a "multiplying edges" message, but then - nothing. I am including a pic, but it isn't revealing much to me.

Thank you for your time

Adam
