Once all the points data is made uniform and the required data is obtained clearly the image of points has to be converted into surface using various. Surface modeling provides the ability to create and edit associative and NURBS surfaces.
A surface is a 3D object that is an infinitely thin shell. There are 2 types of surfaces: procedural and NURBS.
- Procedural surfacescan be associative, maintaining relationships with other objects so that they can be manipulated as a group.
- NURBS surfaces are not associative. Instead, they have control vertices that allow you to sculpt shapes in a more natural way.
Use procedural surfaces to take advantage of associative modeling, and use NURBS surfaces to take advantage of sculpting with control vertices. The illustration below shows a procedural surface on the left, and a NURBS surface on the right.
A surface model is a thin shell that does not have mass or volume. AutoCAD provides two types of surfaces: procedural surfaces and NURBS surfaces.
