Hello Andrei,

Your first mistake is that you don't have the slightest idea how the model should look for the original posters application. Since you are ignorant of the models application you are making assumptions about how it should look based upon your knowledge of inexact poly modeling, which is about as far away as real world manufacturing is to one of your spaceships. It's obvious that you (still) don't have a grasp about surface continuity or its importance in the manufacturing industry. The funny thing is you don't even need to be in the mold industry to understand why the method of construction he used will help him if he needs to make modifications to the part. If you bothered to read what he posted it would be obvious why he is constructing the model that way even based upon that limited information. He made it clear that certain areas of that part were off limits, what part of that don't you understand? He asked for assistance for a particular area of the model. Do you honestly believe that you somehow managed to find a multitude of "mistakes" with this part for his application based upon your work in fantasy world poly modeling? You do realize if he is not methodical and detail oriented he can easily make a million dollar mistake (actual dollars, not space credits)? By the way, it's not a cylinder and you managed to take wrong measurements. Might want to make sure of the basics before attempting to tell someone else they're doing it wrong.
