tks for your reply.
i used draw curve/arc/tan to have this object done.
actually,you can extrude in rhino,but after many tries, now i found that you can extrude with optional "along the curve"
hope it helps.
I have opened the file but when wanting extrude closes the MOI program and tells me that there is
the to send a report to MOI but I doesn't send it for fail in outlook Why?
Hi Juan, maybe it is a bug in the bug reporting mechanism?
Anyway, you can send this file to me manually - there is a file generated called moi_report1.zip (or moi_report2.zip, etc...).
These will be written to the MoI directory in c:\Program Files. If you can find any of those report zip files, please e-mail them to me at moi@moi3d.com and that might help me figure out what is going wrong.
