Member MadMan Posted December 3, 2018 Member Share Posted December 3, 2018 Hello ! I have this problem at importing a mesh. In rhino is ok shaped and I export it as obj or stl. This is the model in rhino. This happens when I import is as OBJ... mesh is changed... new polygons appears but the details are kept like the initial model. Only mesh is in addition. Why ? AND this is when I import as STL... NO addition but the details are hardly affected and the mesh looks awful.. After the RES+ for STL imported it looks like this... What can I do ? I want to import a clean model for surface detail modelling ? Can anyone help me ? Thank you ! Quote Link to comment Share on other sites More sharing options...
Carlosan Posted December 3, 2018 Share Posted December 3, 2018 This issue could be accounted for on the Rhino side via the command SelClosedMesh or SelClosedPolySrf prior to export. Related... All you need to do is increase the resolution in your layer before you import. In some cases, you can increase the resolution of the model before committing it to the scene in the dialogue box that comes up, by subdividing, but I don't find that useful. I almost never check 'merge without voxelizing,' but others have had trouble with this. The reason to merge without voxelizing is so that you can work in Surface mode. You can still voxelize it afterwards, but, again, the resolution of your layer might need to increase. Quote Link to comment Share on other sites More sharing options...
Member MadMan Posted December 3, 2018 Author Member Share Posted December 3, 2018 (edited) And I import it as STL or OBJ ? I imported stl and used flat subdivision before apply Edited December 3, 2018 by MadMan Quote Link to comment Share on other sites More sharing options...
Carlosan Posted December 3, 2018 Share Posted December 3, 2018 Try both and test. Quote Link to comment Share on other sites More sharing options...
Applink Developer haikalle Posted December 4, 2018 Applink Developer Share Posted December 4, 2018 I also suggest to play with resample tool instead res+ and choose from resample option "Linear" Quote Link to comment Share on other sites More sharing options...
Member MadMan Posted December 4, 2018 Author Member Share Posted December 4, 2018 Ok I tried everything you said... the only way the mesh is not affected is STL import and before committing it I click flat subdivisions until I have about 11 millions poly. After that if I resample mesh is affected... as you see below. I can make flat subdivisions till I am happy with the model but is hard for my PC to go over 50 millions triangles... it crashes Quote Link to comment Share on other sites More sharing options...
Carlosan Posted December 4, 2018 Share Posted December 4, 2018 Do you have a computer powerful enough to support that density of polygons? https://www.windowscentral.com/how-use-performance-monitor-windows-10 Quote Link to comment Share on other sites More sharing options...
Member MadMan Posted December 4, 2018 Author Member Share Posted December 4, 2018 It supports almost 50 millions... but crashes when I try to export it... so is not ok because I need more than that Quote Link to comment Share on other sites More sharing options...
Advanced Member Falconius Posted December 4, 2018 Advanced Member Share Posted December 4, 2018 Seems to me there is a problem with the mesh Rhino is exporting. Especially with the ngons on the roof. Is it possible to triangulate it in rhino before hand? Quote Link to comment Share on other sites More sharing options...
Member MadMan Posted December 4, 2018 Author Member Share Posted December 4, 2018 Is much better with mesh triangulated at export STL. As OBJ the same problems. I am trying to have more mesh polys before exporting as STL. Is a start, I don't need millions in 3D to look ok, but still need a lot.
