Member markus Posted November 21, 2009 Member Report Share Posted November 21, 2009 hi all! some of you will remember that i stumbled into this forum a couple of months ago. i had to abandon the project i was working on back then for another one which is finished now. so i am glad i can get back to finding my way through the 3dcoat basics so - again - here's what i would like to do: -> import obj from file. -> check mesh for holes and ideally close them -> up resolution for smoothest surface possible -> export as obj. ps: the mesh should be optimized for cnc cutting let me screenshot the steps, so you can see the settings i use, and where i should tweak for better results. ok 1) import: i scale the size to about 100.000 polys. can i hit "make mesh closed" here, to close holes? 2) more smoothness needed. subdividing here does not work, so i go for quadrangulation. 3) i would then go and quadrangulate the object (settings ok?) 4) the quadrangulated mesh 5) i hit "subdivide 3x" to dense the mesh 6) ready for export 4) thats what the file looks like in cinema4d. not really smooth though ok ... i am sure, there is a better method than the one i chose can someone point me in the right direction? thanks for helping markus www.humanchaos.net Quote Link to comment Share on other sites More sharing options...
Advanced Member lc8b105 Posted November 21, 2009 Advanced Member Report Share Posted November 21, 2009 Hi markus, Since you are preparing the model for CNC cutting, I don't understand why you use quadrangulate. Isn't Triangle better than Quad for CNC? (Correct me if I'm wrong. ) You can try another workflow: 1) The same as yours. 2) If you want more smoothness, you don't need quadrangulate. Just play with "Inc.res" and "Smooth all" those 2 buttons in Voxel room. Hold on "W" key to preview the triangle mesh wireframe. (It is mentioned in my "3D-Coat Hotkeys Master") 3. Go to "File" - "Export" -"Export scene". This will export a high-poly triangle mesh. Hope this helps. Quote Link to comment Share on other sites More sharing options...

Hope this helps. cool ... thank you very much for the tipp. will try right away. one question though if i may: -> does "make mesh closed" in the voxel room do what it promises, and make a mesh really "waterproof"? ie: is it the appropriate method to get models fit for rapid prototyping? -> does merge as skin add real thickness to the mesh? (an important requirement for rapid prototyping as well) thanks for helping again markus Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted November 21, 2009 Report Share Posted November 21, 2009 If it answers your question, all voxel meshes are waterproof, that's just the way voxels work. Closing it first is just because sometimes open meshes come in a little messy. Quote Link to comment Share on other sites More sharing options...
