There maybe an easier way. This is what I found worked.
To have the Partition walls included, under Style Manager, Walls Styles, the wall type using, Components, Dimension, Check Center.
Then insert walls dimension, do not have Parallel Dimension check next to finished button, Select your main wall, Hold Shift Key, and select all the Partition walls wanted, Click Finish, Click for placement and then angle. I hope I did not forget a step, if I did please ask.
