Does this layout show the return ducts?

No. It shows the supply trunk and branches only. Add returns in ArcSite, usually in the hall or each bedroom, for a complete layout.

Can I move a register?

Absolutely. Drag it to a new spot in ArcSite and reroute its branch to the trunk.

Can ArcSite count my duct and fittings?

Yes! Trunk sections, elbows, and registers all come out of your product library as you draw, so you're not counting fittings by hand afterward.

HVAC Duct Layout Drawing

A trunk-and-branch system is a common duct layout for a second floor, with one main line down the hall and short runs off to each room. ArcSite's HVAC duct layout drawing runs a single trunk across the floor plan and branches it to seven ceiling registers.

Seven branch ducts

Step the trunk down in size as branches come off it, so air pressure stays even all the way to the last register. Draw the trunk and branches in ArcSite, and you can check every run length before you order duct.
