]I see. I think you can assembly the whole thing with nothing but the plane alignment constraint. The plane alignment constraint has a property named 'Offset' to let you customize your positions. Three plane alignment constraint for each pair of parts can completely fix them in any relative position. Be aware though, three plane constraints is in fact over constraining the parts. The solver can handle some redundancy. In case it fails, you can try set the Assembly container's 'AutoRelex' property to see if it helps.
thank's for the tips ! I will keep the "AutoRelex" in mind. I might not use it here, but I think in some future project, it will be really usefull!
About the sub-assembly, think it this way. For these kind of DIY product, you'll need some kind of assemble instruction. You treat each manual page as an sub-assembly. This will make it easy for you to later on trace back the parameters, like the offset value mentioned above.
I think I got it, so I will first try to make a "savage" assemblie and then I will redo it with sub assemblies.
BTW, I noticed 3 "bugs"
First and I think easy one to fix, is that when you select a face, every edges more the face are highlighted. It wasn't the case in the previous release.
Second that I can't reproduce (and that have really no consequencies but I report it, just in case) is that after creating constraints, all the faces I used were highlighted in red (magenta?) and my model looked like a shrimp. Restarting FreeCAD solved it, and as I can't reproduce...
Last one, more disturbing, is that I cant select a face of a 2 similar face.
I joined the files, like that you can test it. (I think sub assemblies should solve the problem, I will try just after that post)
I want to make a plan alignment constraint between the two part highlighted. To Highlight them, I cheated, and selected the face to constraint for the first one, and an edge for the second
