### Cad Grid Size for Pointcloud Cad Auto Alignment

When doing an Auto Alignment of a scanned cloud of points to its CAD model, PC-DMIS generates a temporary pointcloud from the CAD model. This entry usually defines the distance between points in that grid. This helps improve some alignments in certain circumstances. For example, if your part has a large planar face that is not scanned, defining a negative value here generates a temporary pointcloud using default CAD model vertices (usually OpenGL vertices), resulting in a better Auto Alignment since planar faces are in general represented by a lot less vertices than other types of faces.

Entry Name: CadGridSizeForPointcloudCadAutoAlignment

Entry Type: Double value.

- The default value is 0.0. With this value, PC-DMIS uses a default distance between grid points that is calculated internally based on the size of the bounding box of the CAD.

- If the value is less than 0, PC-DMIS uses the vertices of the tesselated CAD model and generates a temporary pointcloud to compare to the actual pointcloud.

- If the value is greater than 0, PC-DMIS uses this value as the distance between grid points.
