They are easily editable because if you want to change the shape of a surface, you're just changing the math of the curves that generated it. Since they are driven by mathematical curves, and not a subdivided mesh, they don't have a 'resolution.' A good analogy is raster:vector graphics polygons:NURBS.

'Surfaces/NURBS' are shapes described by boundary curves. And when they send a file to be 3D printed, that is also a polygonal mesh. Many engineers don't realize that when they model in Solidworks, they are really looking at a polygonal approximation of their 'solid' model, generated by their graphics card. A model can be smoother and more refined the more polygons you pack into it. Since there are faces, you can store information additional information such as color and 'flow' of the model. Polygonal models are extremely versatile and are the backbone of CGI, 3D printing, etc. Those triangles have edges (the connectors) and faces (the filled-in triangle). 'Polygon meshes' are points in space connected together to form a 'mesh.' They consist of points which are connected into triangles. There's not much you can do with these outside the realm of scientific experimentation/measurement/visualization. Looked at together they form a 'cloud' of separate points. 'Point clouds' are extremely basic: points in space literally represented exactly where they are, (usually) with no additional information. This revolutionizes the way organizations conceive, develop and realize new products, delivering competitive edge through innovative customer experiences.There are 3 primary ways to store 3D data: This enables multiple disciplines to leverage powerful and integrated specialist applications across all phases of the product development process.ĬATIA’s Design, Engineering and Systems Engineering applications are the heart of Industry Solution Experiences from Dassault Systèmes to address specific industry needs.
