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.
CAD DATA CREATOR SKIN
It offers a continuous view of 3D measurement data, much like stretching a skin over the measured 3D points. A mesh is a representation of the 3D object using a set of polygon surfaces.
In the context of 3D scanning, the point cloud represents the set of points measured on the object surface and maps the surface in a 3D space. A 3D point cloud is a set of data points associated with X,Y,Z coordinates.You’ll need to follow a step or two beyond the software supplied with our systems.įirst, some definitions of the types of data produced by Novacam systems (described in previous blog article): The answer is yes… not directly, but we can get you started
