Cloud to Swatch

The Point Cloud to Swatch relationship can be thought of as a surface point analysis tool. It is an even more specialized cloud to surface face relationship that also takes a reference point on that surface as an input.

When a swatch point is built, selection is performed in a couple of separate steps:

The Filter process

Swatch Points monitor the relative position of a point cloud and the the reference point on the CAD. They dynamically extract and build a mini proximity cloud based on specific settings found in the Swatch Sample Extents dialog.

These proximity settings define a cylindrical zone on the surface of the CAD model centered at the reference point and using the local normal from the CAD face to define the cylinder axis.

The resulting computed point uses the average distance values in the cloud swatch to compute the point offset. This ensures that the offset is correct even on curved surfaces.

Use the Cardinal Point Location button to define the output collection and group for the computed point.
