Magnetic-Joint
See: Add Magnetic-Joint.
A Magnetic-Joint makes a circular profile in a Part become in continuous contact with an irregular* Profile in a different Part.

The Magnetic-Joint dialog-box has two separators: Curve Following Options... Radius Control |

☑'Enable Magnetic-Joint' check-box is active The circular Profile is in continuous contact with the irregular Profile or Point-Cloud. ❑'Enable Magnetic-Joint' clear the check-box. The circular Profile is not in continuous contact with the irregular Profile or Point-Cloud. |

Optionally, edit the effective radius of the Cam-Roller. ❑Not Overriding Circle Radius (default) The circular Profile moves along the irregular Profile. The Radius parameter is 0mm and Read-Only ☑Modify Circle Radius Click the check-box to let the circular Profile overlap irregular Profile. Radius •When the Radius parameter is '0mm', the center of the Circular Profile moves along the Irregular Profile as normal. •When the Radius parameter is '3mm', the center of the Circular Profile is 3mm inside the Irregular Profile. |

This is useful if you use a CMM machine with a probe diameter that is different to the Cam-Roller, and the CMM software does not have 'Probe Compensation'. When the CMM data does not compensate for the Probe Diameter, you would use Modify Cycle Radius to recreate the contact between the irregular-Profile and the Cam-Roller. Offset Profile Radius = Radius of Actual Cam-Roller – Radius of CMM Probe R = Rcf – Rp Rcf = Cam-Roller Radius; Rp = CMM Probe Radius. |
