How to convert STL to SLDPRT: says to many surfaces
I got this STL file which I gonna build on, when I try to convert it a solid body it says it has to many surfaces. How do I do?
The helmet is symmetrical, so one easy option is to try cutting it in half. In just a moment, you'll have ~50% reduction in triangle count!
Different versions of SolidWorks may import the model as is. I've heard that the 2016 release allows for many more triangles to be imported.
A similiar option is to use the "Scan to 3D" plug-in with SolidWorks Pro. It should allow the import of large mesh files, but as Trinityscsp pointed out, the options after import are limited.
A third option is to convert the mesh to surface data. The software to do this is pretty expensive, and smaller details are often lost.
I converted a half helmet to a surface so you can see if it works for your application
