Rallydaz,
You can't project individual bodies of a part file.
The philosphy of V5 is, for instance,
If you have 2 pieces of plate that get welded together,
then you model them as 2 individual parts and insert them
in an assembly and constrain them together.
The philosphy being, when creating your design model, you should be building it up exactly how you would make in real life. (ie, individual pieces welded, bolted etc together)
Then when you create your drawing you can use Overload Properties to control what you see in the view.
Unfortunately using Overload Properties only lets you select one part at a time and if you have a large assenbly this can be time consuming.
You can use SCENES to control what you see in views.
You can select assemblies and single parts in the SCENE to
not be shown when you project the drawing views. (Quicker !!)
I have found that if you start to delete elements fron the drawing views the Drawing file size increases dramatically.
So try to avoid deleting too many elements from the views.
But as catiajim said, you can get the deleted elements back
but ALL !!!! of them come back and you have to do it all over again.
Hope this helps,
Jakey
