Showing model sketches in a drawing

I design textile machinery, and there is a regular requirement to show the
yarn paths through the machines.
I've been doing this by creating either 2D or 3D sketches in the assembly
models, and just using sketched liines to show the yarn paths, without the
overhead of actually creating solid geometry.
When I come to the drawing, I have to set the "view" options to display
sketches, and then I have to select each sketch in the Feature Manager tree
of the desired views and "show" it.

Sometimes this is straight forward, but on a recent job, the sketch was in a
sub-sub-assy which was patterned 40 times in the parent assy. I therefore
had to plough my way through a complex tree to find each of the 40 instances
to "show" them.

I've also tried making the sketched yarn paths as a part added into the
sub-assy, but that has the same problem. It would help if SWX had some
decent tools for manipulating assemblies, such as being able to select all
instances of one or components.

Is there an easier way to achieve this?
Just to add to my time, the next day when I opened up the drawing, all the
sketches were hidden again!!

I can't fix the problem in general, but here's how I do it: Make sure the
sketches are visible when I create the drawing view. they will be visible
in the drawing. Then I use convert entities to make permanent, linked
copies of all the sketch segments (select chain is a lifesaver here). After
that, I usually hide the orignial sketches from the view (hiding them in
the model doesn't seem to affect the state in the view if they were visible
when the view was created). If you show these lines as solid, you may not
need to hide the sketches.
