Hi everyone,
I am a newbie with FreeCAD, using it a week or so now.
This is my first post and I am not a mechanical engineer, so please excuse
if I still use wrong expressions or are not clear enough (such as the somewhat bulky subject).
My config:
FreeCAD 0.19.23578
Assembly 4 workbench
Windows 10 20H2 64bit
I design a table, assembly "Multifunktionstisch".
It is made up of several sub-assemblies: "TischplatteAssembly" (has a small table plate and a big one), and "TischbeinTopAssembly" (the legs, actually will need 4 of them, each leg has a square tube and the leg top plate).
I created 2 LCS, one on subcomponent "TischplatteKlein" (small table plate), and one on "Deckplatte" (leg top plate).
I want to use those 2 LCS to position the leg to a specific location at the table plate.
See pictures, blue lines for assembly hirarchy, red lines for LCS.
My questions:
1) When I link TischbeinTopAssembly into MultifunktionsTisch, then in the "Place linked part" dialog I see none of the LCS I had defined on sub-component level. I noticed that LCS created on components don't seem to propagate through assembly hirarchies.
Is that on purpose or am I doing something wrong?
2) What is the best way where to define LCS to attach subassemblies to each other? On a component (model, body) that a subassembly is made of?
Or on a higher level (assembly)?
3) Why is LCS_TischbeinVorneRechtsAttach placed directly under element TischplatteKlein, and
LCS_TischplatteAttach is placed under Model under Deckplatte?
I guess I made a mistake in activating the correct element in the first place.
Where should an LCS be placed within a part?
4) If I try to drag the LCS to a different location inside the same assembly element, then it changes the hirarchy of the other
elements (pad, body) depending on from where to where I drag and drop.
I don't understand why.
Thanks in advance for your patience and support!
Jens

Re: How to use LCS of parts in different sub-sub-assemblies to attach under new assy?
OK, I need to import the datum (LCS) into the sub assembly from the linked part, before it is selectable by the next higher level assembly.
