This isn't a beginner tutorial. Fixing CAD topology is a headache which can take hours on detailed models like this. Learn the basics of topology to ensure you can follow this type of stuff.

No, you cannot separate the surfaces from the bevels (in a straight forward way). The best way to export from cad that I know is using MOI 3d, their FBX export settings are great and topology actually translates really well to poly modeling, almost no work needed after. A game changer for cad users like myself.

Good input, thanks for the insight.

No, you can, just explode into separated surfaces directy in CAD

@MrElposto 4 месяца назад

@@azweinger sure, but you'll end up with several separate bodies, and hoping that the export algorithm places verts and edges on the right places so you can weld them or something on blender. There are a ton of ways to do the same thing, it depends on your work flow, if it's a solid model or a surface model, what you intend to use it for and etc. I personally wouldn't do it that way.

@jjc1mowery 4 месяца назад

I import many CAD models into Blender, and I first do Limited Dissolve with a 1-5 degree angle. This makes the model much easier to work with in most cases. Also, a Weighted Normal modifier fixes most of the shading issues.

At 1:30 you can use select linked faces flat. Tris to quads also handles most of the bevels properly if you crank the max shape angle.

Great video as always man !! This workflow is a big part of my job day to day as im working with engineers. Im actually working on a plugin for about a year to simplify this process, I will let you know when it's good enough to be use ;).

@D0ragg 4 месяца назад

If you use plasticity, then there is a plugin for blender that allows you to reduce the number of polygons. If you use Fusion 360, then you will need ''moi3d'', where you can adjust the number of polygons.

@SVI_graphics 4 месяца назад

The simple way to work with CAD models is to use an other software to clean it up before importing it to any other software like maya or blender. It wont be perfect but it will be much more clean than the one you are cleaning on the video

@Manetko1982 4 месяца назад

Plasticity has decent export options as well (not to mentione their "blender bridge" function, which is pretty mind-effin-blowin'). Primo stuff as always dude!

@seankelly5318 4 месяца назад

I don't know of any easy route with this but some things that might help are - Alt J - convert to quads and merge by distance to fix the loose edges. Also what about shrink wrapping new geometry over it, using it as a guide mesh.

@platypus001 4 месяца назад

in solidworks, at least you can save separate bodies as diffrent meshes. not shure about faces. you could, possibly, painstakingly cut it with separate bodies. but at that point just do it manually in blender

@user-sx7ss9bh1i 4 месяца назад

i've been using cad software more than 2 years and i get the same problem while importing it in blender , what i normally do is alt+j to make tries to quad than limited dissolve then i add required cuts or if you know from the beginning that you are going to import the model in blender just make simple shapes and the necessary holes in the cad and then add the bevel in the blender. if you use moi3d it does give you option to export in either polygons or tris and quad also thanks Aryan bro for the amazing tutorials.

@FlickerJab 4 месяца назад

I usually run the tris to quads operation first and play with the angle. Then I'll go in manually and work on the parts that are still problematic. Btw neat trick about the bevel width variations, good shit as always brother!

plasticity is working towards making cad export workable meshes, from what i'm seeing, its highly usefull for game pipelines using ngons (i prefer ngons over subd for optimisation)

@fotofx9589 4 месяца назад

These are good techniques to add into a CAD to Blender workflow for sure. I unfortunately get most of the models sent to me via Solidworks as that is what the engineers at work use. It’s so tedious and time consuming. I usually do a limited dissolve then remove problematic edges and add in cuts to fix the artifacts. Sometimes it’s easier to just recreate the model in Blender. Will give some of your techniques a shot on my next project. Thanks for sharing.

@kalpit3d934 4 месяца назад

Try plasticity and say solidworkers to export in step file format. Then try exporting to blender, you will have less pain and even can edit model in plasticity before exporting...

in Rhinoceros, if its still nurbs or solid model on cad, you can separate all faces (bevels or surfaces). But after converted it or exported with mesh/polygons (.stl/.obj) it is too late.

In cases like this, i think its better to do the model again, with the base model it gets easier, retopology in this case is such a hell of a pain! The model is messed up! Just redo it with clean topology! This make the diference between the artists, some just dont care about make an optimized/clean model so he could sell/use in any purpose!
