Convert model made of surfaces to solid

[jr.stipp]

Hi Autodesk Community!

I have a 3D File (stp/step) which is completely made of surfaces. Whenever I want to 3D-Print this file (.stl or .obj), I get an error that my file has negative volume or something isn´t defined.

I want to convert my Surface Model into one single Solid and I think one way to do this, is by stitching every Surface in every component and combine the bodies after that. But since this Assembly has a lot of components  I was wondering if there is another way of fixing my Problem. 

I alreay tried converting my File to .stl and then using the "convert mesh" command to create a Body but it has too many triangles, even after reducing.

I am running out of ideas I´d be so glad if someone could help me out or give me an advise.

Thank you!

don't convert it into a mesh, this will just make it more complicated.

As how I see it you either stitch the faces in the Surface module or you get a "clean" solid model on grabcad for example.

I tried stitching several components and got clean bodies. Those can be 3d printed, though if you scale it very small you will have to thicken the parts or they are to thin to be printed

1. How in the world are you going to print that? The corrugated sheet metal wall thickness is less than a sheet of paper.

2. Here is an idea - if you use Autodesk Inventor Professional and set to Stitch - it is automatically stitched to solids when opening.  If you are a student you can get Autodesk Inventor Professional for free.
