I am trying to make a pocket watch based on a file I got from Thingiverse but it only came as a stl but I cannot open the download to alter it any ideas?
You can check this, see image. Solid body/Surface body instead of the default Graphics body.
As Ingvar mentions, you can use the Solid Body option but that will only work if your object has approx 15,000 triangles or less.
If you have Scan to 3D in your license, you may have some additional options. If your object has more triangles, or you don't have Scan to 3D, you probably will have to look at a poly modeler to make the changes (ie Blender, 3dStudioMax, Modo etc.) since SolidWorks is not really designed to work with meshes.
15,000 triangles are almost nothing... I don't understand the utility of 3D to scan if Soldiworks can not open STL larger then 15,000 triangles
Kaitlin... I've done it many times and imho.. it's a painful process... to convert.. The best option is to get what you can (xsections/profiles).. and re-create the part from scratch.
btw,.. what pocket watch is it...?
