To make sure a complex model is up-to-date:

1.Click Rebuild Now.

2.If enabled, click to disable Auto Rebuild, and then click again to enable Auto-Rebuild.

3.Move the Master-Machine-Angle to 0. Do ALT+H or Run menu > Home.

4.Edit a Part, then exit the Part-Editor. This also rebuilds the model.

5.If there is a 2D-Cam in the model, edit the 2D-Cam, then close the 2D-Cam dialog.

6.Click Rebuild Now again.
