Hi
1.You can save the Selection ( Sheets ) as A1, A0 etc..and use those selections while printing.
that will save some time.
2. You may create a folder in Revit Sheets as per Sheet size...so that you can identify the sheets easily.
3. Or name the Sheet number in such a way so that its easy to find sheet size..
4. You can print all the sheet on one size ex ( A3) using fit to page... if you really want to print all
in one go and same PDF size.. ( this will defeat the scaling, cause sheet might say 1:100 on A0, 1:50 on A1 size..
and new A3 PDF and scaling wont related....
You may place a note saying
a. Scale 1:100 at A0 size
b Scale 1:200 at A1 size
c Scale 1:400 at A3 size... something like that to identify the scaling..
But correct way is whats mentioned by @andybrack.. create separate PDF on correct sheet size and combine them..
or have combined sheets as per size.. like
A0 Sheets ( Sheet 101, Sheet 102 , Sheet 103 etc )
A1 ( Sheet 201, Sheet 202, Sheet 203 etc )
that way anyone who is gonna take physical prints, can identify the sheet size.. and wont print on wrong sheet size
with wrong scaling...
Hope that helps..
Cheers
