John12, As one of their first users and the very first user on Skeychup3D forum,at any time it would be a pleasure to email you a copy of my receipt for SU. As a matter of fact, I would urge to to call the SU people and please talk either to Brad or Tom or Bryce or Yasser or Sara or Jim or John or Brian( I think I am missing few more)and ask about me. The name is Nick Noakhtar and the company name is Noakhtar Design & Associates. Their telephone number is (303)245-8562. After you talked to them and verified that I have a registered software and satisfied your juvenile curiosity, I would expect an apology. I am sure you can be mature enough to oblige that. As far as the segmentation, if you are talking about the number of arcs which would make a circle and so forth, I should say that I already know about that. The question was since both files are 3ds format, how is it that they render differently. If there is another concern that I might not know about it or I might have missed in regards to segmentation, please advise, and maybe I should review some of the things again. Please, speak wisely
