One of the advantages of using 2D drawings generated from a 3D model is that any changes made to the model mean that the drawing sheets are updated automatically. This is fine in theory.
My question is, how do people deal with drawing sheet revisions?
eg. I have 3D model A from which I generate views attached to sheets, with no revision. I can't update/amend 3D model A because these changes will propogate to the (non revised) sheets. This means that I have to copy Model A to create Model B which I then can update and use it's views to attached to rev. A drawings sheets.
Any thoughts/comments welcome.
These are two issues
One for working in the models and drawings
and One for notating the changes in the 2d files
All our work goes to the job site in 2d files so that is a major focus.
Easy way would be to submit an entire job. You would have to have some coordination with the sheet borders
Then when you start making changes tell the computer you are now working on Bulletin or Revision and it will number it accordingly.
Then all changes would be prescribed from-to a date
Then when in a drawing model it should hilite all items within that date while in the drawing model not the actual 3d file
Then you can notate and the computer keeps up witha notation level (Rev1, Rev2, etc) whichever is appropriate
Let the computer keep up which annotations are displayed (all or current revision)
Then the sheet would look to see if any revision marks are shown or NOT in the visible portions of the drawings and add that to a revision list for that sheet.
Process works with Element attributes, smarter sheets which are already needed for sheet titling and coordination, and revisions

I am in a drawing view where I need to make my Revision marks.
I tried what you suggested and nothing happens.
If I go to the model I am out of the files I am working in

Go to EDIT>SELECT BY ATTRIBUTES>BUILDING>>DATE AND TIME and you can filter out what you want as long as it is 3d TF-elements.
Don't know why it doesn't work in BV/DVs.

If by "revision" you mean "bubble" and you are expecting revisions to be listed in the title block, we do not have any of that. That said, we have thought about it, but there is no way to hook everything up and make it customizable, etc. Design History is a more basic capability that simply allows you to see differences. It is a more efficient and convenient way to make copies of your files at milestones.
If the structural guy understands design history, they will have no trouble identifying the changes in the 3rd model and in the drawings.
There are two issues here. The drafting and control of the 2d cocuments. A method to keep up and deonte the active change. (Revision 5 is bubbled and active and FOUND on all documents while all old Revisions are no longer visible. Each sheet has the total revisions that effect that sheet. And a method that no revision has gone UN-noted. And How do I know that a changes I've made are identified so that I may make annotations ie. R5
Then there are the changes and how they are visible to others workign on the drawings. If I give my model with changes made for two weeks to my structural HOW will be know what has changed in the 3d model or 2d drawings so that he makes changes to his drawings and then annotates accordingly.
