Point-Cloud FB

When should I use a Point-Cloud FB?

Add and edit a Point-Cloud FB to import a “cloud” of or data points, and fit a Curve (with a harmonic series) to the data. We can plot and differentiate the Curve.

You can use a Point-Cloud FB to import the shape of a Cam and find the motion of a Follower.

Terminology and Definitions

Point-Cloud :

Data-points that represent the planar shape of a body. The data-points must be cartesian () or polar () coordinates.

Curve :

A smooth, continuous function that we fit to the Point-Cloud that we can use to replace the data-points. From the continuous function, we can evaluate the coordinates of the planar shape at any machine-angle.

Point Cloud FB :

Add to a Part.
Use the Point-Cloud dialog to:

•import coordinates of a planar shape, and to

•fit a Curve to replace the coordinates
