It is possible to have plans for each sub-assembly just as we do not commonly have plans for each part that constitutes a sub-assembly.
All you have to do is open the sub-assembly and make a plan of it.
Once the sub-assembly is opened
click File ==> Create a plan from assembly.
Repeat the operation for each subset. From the global assembly you can make a plan with these sub-assemblies which then each appear as a single part. If parent-child stories speak to you.
My little comrades will surely give you a simplification by using the configurations, if you have a lot of assembly variations. I'll let them explain to you because I never use configurations.
If it's not clear, I'll give you a concrete example
I hope there are the configurations in the main assembly. If so, it's easy to call the assembly in a mep, choose the config to display (at the top in the feature manager). If necessary, you can add views of other configurations or optional S/E. The next question is what information do you want to appear in the title block.
We work with a main ASM and what is optional are sub-ASMs. For MEPs we make the bare plan and then we create the different tabs, we click at the bottom on the one we just made by doing ctrl-c then we do ctrl-v and we rename with the option that is added in the configuration and so on. A single plan with the different tabs depending on the options....
It is also possible to create several "sheets" in the same drawing file (many people don't know this), duplicate them and move them, a bit like on Excel.
As said @stefbeno the next question is the filling of the cartridge which in this type of case is not always easy to manage.
If you had some time :-) :-) A little tutorial would be very useful because what you describe as a method is very important and should save a lot of time with more reliability. The story of several sheets in the same file piques my interest.
@Zozo_mp: for multi folio, it's indeed, as @Pierre S says, like with Excel: there are tabs at the bottom of the screen:
Then, to switch a view from one sheet to another, you have to do the manipulation in the feature manager. To choose the properties to display in the title block of a particular template, you have to right-click on the sheet/property and then choose the template to use:
You're welcome, I did it quickly so succinct. You'll probably come back with questions.
Just a few small additions: - text to put in a note to display the page number / total number: Sheet $PRP:"SW-Current Sheet"/$PRP:"SW-Total Sheets" - The first page is the leftmost and the last is the rightmost. The numbering is done automatically on this basis. - you can rename (like XL tabs) your leaf tabs.
