![]() ![]() To use a more simple example think of Photoshop and Illustrator. ![]() A CAD application generates a perfectly smooth NURBS surface which under the hood works like a mesh that’s density can be constantly re calculated based on a input data which normally consists of a curve network or solid modeling tools. The sculpting application is generating triangles where they are needed based on your brush input…A CAD application does the same sort of thing, except you don’t see the triangles and it’s a far more technical and less interactive process. ![]() Think of something like dynamesh or voxel sculpting. The “bad” topology you are seeing is actually a baked version of a resolution independent mesh that is generated from vector/spline data. You may already know some of this but incase you don’t I’ve collected some useful tips for importing CAD into a DCC appĬAD models are often complex and at first and can be very daunting to people who have no concept of how it all works. NURBS is often under looked in the visualization world because it is expensive and time consuming and often completely unnecessary when dealing with digital space where approximation and “cheating” reality is encouraged to save compute overhead/time/money. With a NURBS toolset you have fine control over an objects reflection quality and its relationship with the real world which is preferable when you are modeling for manufacturing. NURBS is actually a lot better suited for hard surface models or controlled organic man made objects such as cars. NURBS is an entirely different tool set that generates surfaces based on curve networks or tool objects and primitives. Don’t expect topology that resembles subdivision modeling. ![]()
