How to draw a secondary operation drawing on Solid

Hi experts,

I need your help drawing a secondary operation drawing. I am relatively new to making a drawing on SolidWorks.

We have a vendor who machines a piece of aluminum block into a shape that we design... (Drawing A)

We have a secondary vendor who machines the (A) into more details.. (Drawing B)

Drawing A is a complex design, so we make a lot of A first into stock. Drawing B instructs the secondary machining vendor to machine the block for further modification. The secondary operation is usually a very simple change but very necessary.

Traditionally we have made drawings (for B) by doing the following:

1) Put the top view of the A

2) Overlay the top view of the B on top of the top view A

3) The difference is cross-hatched to tell the secondary operation vendor that is where to be machined.

4) repeat for side/bottom view

This has been done until now because we have been using a different CAD software (but much older) the software let us do that. But now with SolidWorks, I am stuck as to how to do it.

It would be nice by posing this thread to the community, I can know the following:

1) Is there a industry standard secondary operation drawing format? If so, can SolidWorks let us do it easily?

2) Is it possible to overlay one view from a part with another view from another part? And cross-hatch the difference?

3) Is our way totally out-dated? Is there a better SolidWorky way of achieving this?

Thank you in advance,
