![]() So let's say I was going to make something like an incense burner with a nice dragon motif and I wanted it to have a cover that could open and close via a hinge. So what to do? Just keep it in mind while working to try to keep the workflow going from solid model to polygonal model, not the other way around. Generally, you'll end up with a solid model that's not very usable as a solid model because of the imperfect conversion of all of the facets. So, when you import something like a polygonal model in the way of something like an STL file and try to convert it to a solid there will be problems with converting all of the facets. What I mean by not very usable is, well, when you do solid modeling for a while you really really appreciate that all of those triangles are GONE! You get used to working with perfect looking geometry and the software mostly only works with perfect looking geometry. Fusion 360 can import something like the 3D printing industry standard STL ( Standard Tessellation Language created by the inventor of 3D printing Chuk Hull and his company 3D Systems) yet in most cases it won't be very usable as a solid model. Consequently, when you're working with Zbrush or Blender and want to export 3D geometry to edit in Fusion 360 you are going to run into problems. So, the good thing to know is one can convert a solid model to a polygonal model but it is extremely difficult to convert a polygonal model to a solid model. With solid modeling, mathematical formulas are used to describe 3D geometry you're modeling up. While software packages like Fusion 360, Solidworks and SpaceClaim operate via what's known as solid modeling. This works with XYZ coordinates making up points that form triangular faces to represent the 3D geometry you're modeling up. Zbrush and Blender operate via what's known as polygonal modeling.
