Ed,
Another thing you may want to try to help manage the display is to use
layers for placing your geometry. If you are drawing 2D geometry to
represent a part, set up a group of layers for the geometry and the
dimensions for the geometry. When you start another part that will be
constrained to the first, use another set of layers. You may also want to
consider duplicating the common edges of the parts for the second part and
constraining them to the first. You will have overlaying geometry in this
case.
So now you have two parts witt duplicated common edges. If you want to
create a drawing of the assembly, Create a 2D Model view of the overall 2D
geometry. Show the layers for both parts within the context of the drawing
view placed.
If you want to create a drawing of only one part, create a 2D Model view.
Hide the layers of the other part within the context of the drawing view.
You will only see the geometry of the required part. You can then create a
new drawing of the second part and reverse the layer display within the
context of the new 2D Model views.
This is just something you may want to try. Start with something simple like
two rectangles to get the feel of the workflow.
