What is a Point-Cloud?
In general they term Point-Cloud is used in the engineering community to describe a set of coordinates that specify the solid surface of a 2D or 3D object.. In MechDesigner, the coordinates are usually of a 2D-Cam, and the coordinates are frequently measured with a Coordinate Measurement Machine (CMM). Point-Cloud FB dialog-box We use the Point-Cloud dialog-box to import the Point-Cloud data. We also use the Point-Cloud dialog-box to fit a smooth curve to the data. The curve is mathematically smoother than the data in the original Point-Cloud. 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 identify the motion of the Cam-Follower. We can redefine the motion with an improved motion. WE can use that motion to redefine the 2D-Cam. Finally, you can recalculate the cam-coordinates and export them for cam manufacture. |
