It sounds like you usually use AC10, but are on 9 for some reason.
The difference is that you simply save your project file (PLN) which has your elevations etc defined as views in the view map, similar to AC10, then in PM place your elevation view in a layout refering to the PLN file as the source, saving PLN and updating in PM as changes are made.
Does this make sense?
(Some people (a minority I would think) still created PMK files and placed them in PM, but I found that unnecessary in AC9. A leftover from earlier versions)
