I don't know. The document says that a Part is something that "cannot be further decomposed" and App::Part can be decomposed into the LCS and the Bodies/Features inside it. It also says that an assembly contains at least 2 Parts, so if App::Part is "Assembly" then having only 1 component inside it would not be in agreement with the document. The document is pretty solidly in the conceptual domain and doesn't talk much, if at all, about the implementation domain.adrianinsaval wrote: ↑Sun Mar 26, 2023 4:05 pm I'm not sure fi this is correct, from what I understood earlier I think it's not desired to have standalone Part::Feature objects directly under the assembly container, so instead this would be App:Part too.
After reading a little more, I'd like to change that translation. In the case study, the bearing seat in component A and the outer race of component B are Assembly Features. There is another entity called ParametricAssemblyConstraint that says those 2 Assembly Features are coaxial. I don't know what the right translation would be - maybe it is as simple as a Face or Edge.I think it means much more than that, in other CAD systems you do some operations in the assembly, like mirroring, pocketing and can't remember what else. I think this has been mentioned before here too.
I haven't found anything yet about "operations", only data.
