[Vincent B]

How to explain the body is emptying when when I drag the cube inside the part container?

Expand the body and then do the drag. Not sure what your asking.

Confirmed, objects inside the Body get removed when dropping the Cube into the Part.

Could be because of the invalid links to objects inside the body.

I don't see anything removed in my 0.18 or 0.19.20477.

I see it on this version, too:

So it predates the link merge.

I don't see anything removed in my 0.18 or 0.19.20477.

Post your full information as it might be a windows-related issue only.

Maybe a config file issue...

Nothing weird on these machines.

If I remove the support to the datum lines from the box then everything works as expected.

I am guessing that the box is improperly linked to the datum lines inside the body (red arrows on the dependency graph) and when the box is moved it drags its support (datum lines) with it. The other elements in the body that are linked to the datum lines go along for the ride.

First thing to do is get rid of the errors. There may be a bug, but start with a clean model first.

The issue occurs just when moving inside. If you remove the supports before then grab it inside, there're no problem. After that if you re-link the cube, still no problem. But if you remove it from the part and re-put inside, the bug occurs again.

This bug still here.
move the box inside the part container....the body get empty.
