Part #1: Mesh to solid #1.TriceratopsPart #3: Mesh to solid #3. Voronoi cells and t-pipe.Part #4 Mesh to solid #4. Jointing problems.Consider the geometric primitive: sphere. Create a mesh and surface sphere using various variants of construction (Rhino and Inventor). Convert model into neutral format (STEP),and stereolithography(STL). The results are shown in table/I did not upload to the site Triceratops converted into a polysurface ( available on request).But believe me that the file size has increased by 55 times and is more than 500 megabytes.Conversion mesh to surface has not optimal software yet.
