Add Point-Cloud FB

Why should I use a Point-Cloud FB?

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

Terminology and Definitions

Point-Cloud :

A Point-cloud is a discrete set of data-points that represent the shape of a planar or spatial body. The data can be Cartesian or Spherical Coordinates.

Curve :

A smooth, continuous function that we fit to the Point-cloud to replace the discrete coordinates of the Point-Cloud. 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

OR

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.
