You create sub-meshes that you later extract as analytic or non-analytic surfaces.
The goal is to separate areas of specific design intent, for example: areas that are planes, cylinders, cones, b-surfaces, etc. Each specific area must be its own sub-mesh, as indicated by the different colors. You then refine the design intent using paint tools to split sub-meshes or join separate sub-meshes. Areas designed for b-surfaces require more attention to remove inappropriate curvature and jagged edges.
Automatic Painting
| Select sub-mesh to decompose |
Activates Automatic Painting for the selected sub-mesh.
|
| Sensitivity |
Dynamically updates the preview of the selected sub-mesh when you move the slider. When you first open the PropertyManager, the entire model is pre-selected, so Sensitivity affects all sub-meshes. This is the only time that all sub-meshes are group selected, so be sure you have adjusted Sensitivity as desired before you click Apply.
Sensitivity sets the maximum angle of incidence permitted between triangles, measures the angles, then joins or separates triangles based on the setting.
