![]() Here is PolyWorks Inspector tutorial video on this subject. You can also impose constraints on the extracted geometrical features – for example, some features can be made coaxial, parallel or perpendicular to each other – to bring their aspects closer to what an original (CAD) design would be. ![]() It provides tools for extracting geometric features such as cylinders, cones, planes and spheres from the 3D point cloud. The PolyWorks InspectorTM GD&T software, which Novacam offers as an option with our systems, can be used at this stage. Various software – both professional and free – exist to help in this step. To convert a 3D point cloud to vector-based graphics, you must first start by segmenting the point cloud, i.e., identify groups of points as representing geometric forms such as cylinders and planes. Step 1) Extract geometric forms from the 3D point cloud So, what’s involved in making a conversion to CAD?Ĭonversion of a 3D point cloud to a CAD model is basically a 2-step process. ![]() It typically includes information such as dimensions and tolerances. A CAD model is commonly defined as a 2D or 3D representation of a mechanical design of an object drafted using vector-based graphics.Novacam system software can also output the acquired 3D scan data directly in mesh (STL file) format. The mesh can be created from a 3D point cloud by, for example, connecting adjacent points with triangle surfaces. It offers a continuous view of 3D measurement data, much like stretching a skin over the measured 3D points. ![]()
