[QUOTE="npdynamite, post: 345612, member: 11802"] Based on your recent post, I would say this is a good design from someone learning the software. It is impossible to give truly good feedback without more marking info and seeing the opposing. From a function and matching the mouth aspect, from what I can see I would guess that the buccal, and maybe the lingual are a little under contoured. Beyond that the main things I see are common to people getting into design. Mainly a general lack of smoothness and clean contours. This is something that only comes with time and practice, though there are helpful tools and techniques to speed it up. The results of improving these factors will be that the crown takes less time to finish after milling. The biggest spots sticking out to me are the contact area, this appears to be undercut and will likely be tricky to get a good contact from. And the margins, there are a lot of "bad" meshes here (places where you can more easily see the triangle shapes that make up the mesh and the triangles are jaggedy). This won't necessarily affect anything, but I have seen it affect the margin milling quality. Again, I am being nitpicky and we don't have enough info to give good design feedback, but these are my couple thoughts [/QUOTE]
