It would also be nice if you could set the Pipe Offset to be to Center, Top of Outside (Including Insulation), Top of Outside, Top of Inside, Bottom of Outside (Including Insulation), Bottom of Outside, & Bottom of Inside. Right now, the orientation only allows for top of Inside Diameter, Bottom of Inside Diameter, and Center, and the "Offset" always goes to the center of pipe regardless of the alignment. In addition to the insulation for piping and ducting, the lining also needs to be accounted for when refering to ducting.
This would be a HUGE workflow benefit and needs to be a priority one item!!!
