Mesh files are primarily utilized for the following scenarios: Although uncommon due to the complexity and tediousness of the process, a mesh may also be manually created. 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. Typically, 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. Pro 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 Neutral CAD files are open-format and not copyrighted intellectual property of any system or CAD program.

They contain the most detail and functionality because they don’t consolidate or gloss over areas of a 3D CAD design file for 3D printing Native CAD files are copyrighted intellectual property of the system/CAD program for which they are utilized.There are, in general, two main CAD file format categories: Native Complex 3D printed part printed by a Fictiv manufacturing partnerīefore we review the steps for CAD file formatting for 3D printing, here’s a brief overview of the different CAD formats. This article will help you understand the difference between these file types, and which are best for uploading to a 3D printer’s CAD software or sending to a 3D printing service.

From STEP files to STL files, to IGES and more, it can be difficult to differentiate between them.

There are a lot of CAD (computer-aided design) file types out there, each with its own names, formats, and parameters.
