Hi,
I would use Simplified reps.
Make a simplifired rep in assembly mode and choose to show it in the drawing view.
Right click on the drawing view, choose properites, choose view display and choose the simplified rep.
Note that you cant show BOM ballons int that view that are linked to the master BOM tabel. You have to make a new BOM table conected to the simplified rep to be able to have any balloon.
The other way is to make a new layer (layer tree) in assembly mode.
Then in drawing mode. Go to the layer tree and choose the view there you whantto hide thepart. Choose hide on the layer you just made (dont forget to save layer status)
Then that part will disappar in that view.
