Problem of importing an STL into solids

Hello everyone, I would like to import an STL file into Solidworks but impossible to make it a volume size, it systematically results in a mesh surface area.

I use the import method with the option Volume body + create mesh sizes but nothing works, I get this message systematically:

"This mesh model can be imported only as a polygon body, not as a solid"

It's an STL that comes out of a CU by simulation and therefore I can't do anything with it in this state.

If anyone has experienced the same problem or has a solution to offer me, I'm all for it!

Thank you

Hello
This happens when the mesh is too complex. In this case, importing as a graphics body is the only option that works 100% (without simplifying the mesh beforehand).
For an MEP this is enough.

Thank you for your answer but unfortunately the graphics body option is grayed out and I can't select it... I only have the solutions of the volume body that doesn't work and the surface body

probably due to the limited SW version. I don't know more. If sharing the file is possible, we may find a solution.

Hello
I don't have too much time to test, but have you tried to sew the faces and then create a volume.
However, having looked for solutions in the past, I don't think there's much you can do with SW with STL files

Hello

I wanted to send you my part so that you can do some tests but the forum does not support STL in the attachments...
I don't know if there are other ways to post it but I find myself stuck again...

Hello

You should be able to post a zip of your stl

STL.zip Tool (3.5 MB)

Thank you for the tip I hadn't thought of it :wink:

To open in SW uncheck mesh body options.

It is a milling tool. It opens but too damaged. The best thing to do is to redraw. 4-5 functions. By overlay.

So I don't have any option to get a perfect model?

Because I try to create surfaces from the mesh, but even a simple plan refuses to be created...

Redesigning the tool using it as a model is my only solution?

I don't know of a reliable and accurate solution at the same time. Even if surface recognition works, the result will be inaccurate. When the part is complicated and the remodeling too complex, I use third-party software that is better suited to simplify the meshing so that I can import the geometry into SW as a solid or surface. In this case, precision does not matter.

Out of curiosity @soring what software do you use to simplify the remeshing (I'm looking for 1 simple and if possible free)

what else than Blender :grinning:
I got used to the interface and the strange ergonomics for a CADist. It is really free and very widespread. Tutorials everywhere. At first I was lost and I gave up every time. But you have to start at the bottom and be motivated. Today it's my favorite hobby.
Attention: simplification = approximation. Incompatible with CAD but so useful sometimes.

Hi all

We use the free meshmixer software to work with STLs, it allows us to easily remesh, fill in the holes/mesh defects, and transform into a solid before doing a STEP export.

Very good Meshmixer solution too. Simpler software than Blender.
