Why add a CAD Control FB
Use a CAD Control FB to synchronize the positions of Parts in a SolidWorks® Assembly model with Parts in a MechDesigner model. Question: Why do this when MechDesigner is perfect to model motions? Answer: Because SolidWorks® has useful tools such as Collision Verification and Interference Detection. The Clearance Detection tool in SolidWorks® evaluates the exact gap between Parts. We can use this tool to check that a 3D-Cam we export to SolidWorks has the same Radial Clearance as we enter in the 3D-Cam dialog-box. Connect motion-values from any of the Function-Blocks to the inputs of the CAD Control FB. When you have configured the CAD Control dialog-box, motion-values that control Parts in MechDesigner are piped to SolidWorks Distance or Angle mates that define the position of parts in an equivalent assembly in SolidWorks®. |

STEP 1: Add the CAD-Control FB to the graphic area
The Cad-Control FB is now in the graphic-area and the Assembly-Tree. STEP 2: Open the CAD-Control dialog-box:
The CAD-Control dialog-box is now open. STEP 3: See CAD Control dialog-box |

Note: It is not automatic that the MechDesigner and SolidWorks® models work together. For example, angles in SolidWorks® cannot be negative, but they can be in MechDesigner. Thus, you may need to use Gearing FBs in MechDesigner to add a constant to the output values so that they have the same minimum and maximum values as those in SolidWorks®. |
