Point-Cloud FB

Why should I use a Point-Cloud FB?

You can use a Point-Cloud FB to, for example, reverse-engineer the shape of a Cam and then find the motion of a Follower.

Terminology and Definitions

Point-Cloud :

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

Curve :

A smooth, continuous function that we fit to the Point-Cloud 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 :

A Function-Block that you add to a Part.
Use the Point-Cloud dialog to:

•to import coordinates of a planar shape, and

•to fit a Curve to replace the coordinates

Add Point-Cloud FB

STEP 1Add a Point-Cloud FB to a Part

Add Point-Cloud FB

1.Click Function-Blocks menu > Point-Cloud

The Command-Manager has one selection box. You must select a Part.

2.Click a Part in the graphics-area or Assembly-Tree

3.Click OK-tiny-11-15 in the Command-Manager

The Point-Cloud FB is now in the graphics-area.

STEP 2Open the Point-Cloud dialog:

1.Double-click a Point-Cloud FB in the graphics-area or Assembly-Tree

OR

See How to Open a dialog.
