Blender has no object joining modifier. I think it would be useful to somehowe achievce it. Can anyone suggest a method for properly doing it? I would like to retain the objects transform, like when simply joining objects, but of course with all the previous modifiers and the two original editable meshes kept non-destructively.
If I want to join A with B, I can add an Array Modifier to A with zero count, using Object Offset with B and setting End Cap also to B.
If A is not centered, scaled or rotated, the two B objects will not align.
I can add a C object and use the End Cap method two or more times, with A and B and other objects I like to join together.
