HELP - Failed to Validate Broken Face - Fully Constrained

[jwhitten]

A MasterSketch is usually a sketch - often outside of bodies if you use it for different bodies - that contains the principal geometry, but not all the details. This sketch can then be used either by Sketcher CarbonCopy, where you then remove the unwanted stuff; or you use a PartDesign ShapeBinder and use it for external references. If you have the MasterSketch in the same body, the ShapeBinder is omitted.
In both cases you then add the details to the sketch.

For the approach you are used to, you would probably have all the details in the MasterSketch and use CarbonCopy.

Thank you for the hints. I will have to look for more information on these concepts and try them out. I think I understand what you're saying generally though. I'm not totally up yet on FreeCAD nomenclature, so I'll have to do some reading.
