Does anybody know how to use AutoCAD or Autodesk Inventor to measure the volume of an exported .obj file? I have been trying to for a while now but I’m stuck.
You might have better luck converting the OBJ to an STL file, which is also a type of triangulated mesh. Then there are some avenues to turn the STL into an Inventor native solid https://forums.autodesk.com/t5/inventor-forum/how-to-edit-an-stl-file-in-inventor-2016/td-p/6400751
Obj files are more for visual than calculation. What kind of volumes are you looking for… and of what? The site offers DXF, XYZ and LAS… LAS goes right into Inventor.The are a ton of programs out there, just depends on what exactly you are trying to accomplish.
