### What is a Point-Cloud?

 A Point-Cloud is a set of dimensional coordinates that specify the outline of a 2D object. For example, the object is a cam. The dimensional coordinates are found by measuring a cam, frequently with a Coordinate Measurement Machine (CMM). Point-Cloud FB dialog-box Use the Point-Cloud FB dialog-box to import data and then fit a smooth curve to the data. The curve is mathematically smoother than the Point-Cloud data. Application Note: Reverse-engineer a 2D-Cam. Measure an old Cam, import the Point-Cloud and define it as a new Curve in the Point-Cloud dialog-box. Use the curve, in combination with a Magnetic-Joint and a Graph FB to find the motion of a Cam-Follower. Use the tools in MotionDesigner to replace the motion with a 'smooth' motion-law. Redefine the motion of the cam-follower with the smooth mathematical motion-law, and add a 2D-Cam. Finally, you can recalculate cam-coordinates.

### Point-Cloud FB

[Above Graphic-Area]: Modelling FB toolbar > Point-Cloud FB

Dialog-box:

Point-Cloud dialog-box

What to do:

 STEP 1. Add the Point-Cloud FB to the graphic area

A Point-Cloud is a child to Part.

 1 Click Modelling FB toolbar > Add Point-Cloud FB

The Command-Manager shows one selection box

 2 Click
 3 Click OK in the Command-Manager

The Design-Set FB is now in the graphic-area and the Assembly-Tree.

Result:

The Point-Cloud is an element that is child to the Part.

Edit:

 STEP 2. Edit the Point-Cloud FB to open the Point-Cloud dialog-box
 1 Explore the Assembly-Tree to find the Point-Cloud that is a child element to the Part
 2 Double-click the Point-Cloud FB to open the Point-Cloud dialog-box
