![]() ![]() The mesh is created by resolving these points into variably sized triangles by connecting the dots. A mesh model is typically created when a part is 3D scanned, which results in a copious amount of data points (dots) that comprise a point cloud. showing impact of tessellations on fine detail image from: Mesh ModelingĪ mesh model, on the other hand, is a collection of small triangles (tessellations) that make up a surface. IGS HOME DESIGN 3D SOFTWARETypically, parametric modeling software (such as 3D AutoCAD) utilizes feature-based modeling tools to allow the manipulation of a model’s attributes. The implementation of parametric modeling originates through the CAD software’s programming, which determines the dimension and shape of the solid model. Parametric modeling is a process whereby the shape of a model’s geometry is automatically changed when a dimension value is altered it’s based on designing features and constraints of a solid body or assembly. In 3D modeling, a parametric model is one that consists of solid blocks or vectors that have both magnitude and direction. IGS HOME DESIGN 3D PROPro tip: For an in-depth review of each format, check out our article on 3D file types.ĬAD files may also be distinguished based on the method by which they were created and how they are structured: They are useful for sharing files across two or more different CAD platforms, but they result in a small amount of fine detail loss when converting to a neutral file type
