Again, I think the answer is no. Without drawing relations, there's no way to control this. You also cannot access the total sheets external to the drawing. In a situation where you have two completely different audiences with two different sets of information, it's begging for two different drawings. I don't think that a drawing relation gets you to where the ideal answer should be. I think you need something more like a "drawing simplified rep" where you can define a configuration for the intended audience but still share information between the representations so you don't have to create duplicate views, dimensions, etc.
There are two more possibilities I can think of, but I've never tried them:
- Drawing representations. Has anyone dealt with drawing representations? I don't have the time right now to test it out, but if you can turn sheets "on" or "off" then it could be useful in a case like this. A quick scan through the help files didn't turn up any sheet based commands. I might test this out later when I have more time.
- Drawing program. You may be able to control variables in a drawing using program but I've never done it. I think it's only used to control states, and with that maybe you can turn sheets on and off.
Am I correct in assuming that the manufacturer still needs sheets 1 & 2?
