I terms of automating construction drawings I think good templates goes a long way. One can have SU templates with all the tags, tag folders, styles, scenes already set up. The time it takes to produce a Layout document copying the viewports and setting them up for scenes is something I just accept, as this is not my main time-thief.
I dont use the condoc/ 5d+ things, as (for me) learning them probably takes more time than setting ut the document manually.
Updating x-refs / external ifc´s is my main time thief. Also distributing updated drawings is time-consuming, new dwg,s and ifc´s out there every week, and producing a set of separate pdf´s for each Layout page named correctly for each revision is very time-consuming.
Just in Layout having the option to print all the pages into individual pdf´s all at once named as the page name would be a very real production time Improvement.
