Currently we utilize Sheet Set for managing our drawing layouts. It is phenomenal AutoCAD tool that gives us the ability to manage all of our information across multiple drawings really well.
Microvellum has some of this by way of the user defined project properties and update title block to, however it has its own shortcomings.
One thing that seems like it would be fairly easy to create is an index we can put on our cover sheet that populates from all of the rooms and categories in the project tree. We have the data already in MV, it would be great if we could make use of it instead of having to re enter this same info into sheet set.
There are other features that sheet set still has, but I'll leave those for their own posts.
