Why when I'm updating a drawing parts are added to the drawing?

[jean-rene.trudel]

Hi!

I need to update one of my design.   I have modify, delete and add some parts.    But when I go to my drawing and I click Update (the warning sign), my parts move in my drawing an some unwanted part suddenly apear.  My drawing is complety ruined.   

I design some kind of metalic case.  Why when I update the Drawing for the door other parts appear suddenly  (they are not linked to the door in any way...)?   

I certainly do something wrong!

Thank you

Hi! The drawing behavior does not sound right to me. If possible, please share the f2d and f3z files here. The forum experts can help take a look.

Many thanks!

I notice that when an assembly is changed and the drawing updated jointed components show in their new position as well as in the old position.

Turning them on and off in the browser fixes this.
