In professional CAD systems, geometry is not stored as triangle meshes but as mathematically defined surfaces (such as parametric and NURBS surfaces).
Triangle meshes are only generated as approximations for rendering.
This is analogous to vector graphics (SVG/EPS) versus raster images (PNG/JPG). Any serious manufacturing will work require a STEP (or something equivalent) which stores these parametric surfaces rather than a mesh. |
