How to edit polygon in DI ?

I have a smaller footprint on the second flr & I am trying to change the 1st
fl roof shape to match.
In Detailed Edit mode, using the component tree & the 3d view I have
identified the roof sections that need changing & their respective polygons.
I open up the polygon's properties but cannot delete the unwanted vertices -
how are these changes supposed to be made?

Hi All,

I have a residential (commercial) project that has large, multi room
residential units. Appendix G baseline calls for packaged terminal heat pump
units (PTHP) for this case. However, when I model these, the supplemental
heat energy use gets outrageously high. When I model packaged heat pump
units (residential) the supplemental heat consumption goes to a reasonable

Any idea why the PTHPs would have such an effect or how I might investigate?
Could it be that these units are primarily designed for one small space? I
have reviewed just about all the QC checks I can think of.

Many thanks,
