Hello Michael

Thanks for the advise, one of the things that I often find when working with CAD systems, I also use Geomagic Design and BobCAD is understanding what the CAD system is requiring behind the scene.Of course this is where MOI is exceptional in that we can communicate with you with your intimate understanding of what is going on within the programme.

Many Thanks

Thanks for your advise, you got a nice result.

I think part of my problem is that I set out boundaries for the plan view and sections and basically I am thinking that I will stretch out a surface over those wire boundaries.

You have no worry about flying extended surfaces past these boundaries and trimming back.

Many thanks

Barrie
