…and machined parts…
Skull Chopper:
Created as 1) all precision CAD NURB surfaces and solids using Alias, Fusion, and Onshape.
2) Also converted, retopologized, or rebuilt as polygons. Optimized as both Blender and Maya file versions. See details below.
Keyshot can easily import huge NURBS or Polygon files. This version has the best of both and it imports all UV maps from Blender or Maya.
Blender and Maya files created with polygons (below)
My Polygon models are almost always QUAD. Sometimes it decreases the number of polygons if you use Triangle around circular openings. The advantage of All-Quads is that you or others can subdivide it to make it smoother or edit easier. Avoid N-Gons = more than 4 sided polygons.
The Polygon version has SQ 5K PBR texture maps for basecolor, bump or displacement,normal,roughness,metallic, and opacity.
These and many other parts were machined from billet aluminum with custom attachment and sizes. Used early T-Splines and CREO for CAD and Machined by Chris Nunn at Concept Reality Parts. Raven Choppers LLC by Dan Dwyer and Chris Nunn.
Modelling techniques for precision 3D CAD. Here are a few alternative ways I used to create the Chopper tank design in 3D CAD. I often use Alias, Fusion, and Onshape. It is possible to even transfer a Quad Polygon from Blender or Maya to a 3D NURBS model.
Both the tank and skull versions below were created with a MIRROR PLANE.
