Protecting your Blender work

Your Edit

After A Later Sync

An object you moved

Stays, until the element moves in Archicad

A material you assigned

Not replaced when only the surface changes (first material slot)

A mesh you edited

Kept if Archicad also changed it; the incoming change is skipped and logged

An object you detached

Never touched again

A saved .blend, reopened

Objects are re-adopted by GUID, not duplicated
