Hi RMA team,
I wanted to report that the quality of imports nurbs and meshes continues to be a huge problem for me to keep using Rhino as part of a much larger workflow. Rhino used to excel in being one of teh best programs in terms of import/export, but I think this needs a lot more attention lately.
FBX: I do not see any material names. The file structure does come in cleanly as layers but materials do not:
OBJ: no parts/objects structure, all flat in a single layer no mater what import option I try.
Also I gte to see some of my materials by name, but also some lose the name and a bunch of extra unnamed materials show up too.
Step: Step assembly structure is coming correctly, but into blocks. I can only make sense of this using Pascal’s ‘ExplodeBlocksToLayers.rvb’ script. I though this wasn’t working well, but it was just because large assemblies take a while to fully expand and I thought it was failing (no feedback of in progress). But I think that most users who are not Pascal fanboi’s (he’s a popular guy, but I bet we are not a huge faithful following) cannot take advantage of working with imported assemblies. I’m not suggesting that layering (what his script does) is the solution, but at least it’s a work around for not having a navigable assembly structure interface. The current block manager is not helpful because it doe snot show a nested structure.
I also get lots of edge errors, open surfaces, weird trimming errors, flipped normals. None of this happens in Modo’s Power translator, very latest Keyshot step importer, Onshape, Fusion 360. I don’t know if they cheat, and maybe they have errors, but at least I can use the geometry fine for reference, rendering, etc. here’s a screenshot of my last import:
Summary: I always want to come to do some work in Rhino but sometimes I find it really really hard by not having a reliable/clean way to import files. Every time I think I’m going to go and use some Rhino I brace myself for the amount of extra work it will be just to open things up and getting to the point of starting to work productively.
I know these things get attention because it’s becoming a growing problem, at least for us.
