When you copy an equipment group, copy all of the equipment connections in it, too. (Currently the group is copied and the group settings, but not the actual pieces of equipment in the group.)

Be able to set a different layer for the schedule header and subheaders.

Be able to break the loop going from an equipment connection to a disconnect.

It would be nice if you could add layer control commands for the associated photometric calculation layers (both general and egress) to turn them on and off like you have for room layers and duct centerlines. The boundaries, foot candles and contours can really clutter up the drawing. Also make it so that when you need to run a general or egress calculation the respective layers will turn back on automatically.

For takeoffs, provide a way to separate overhead and underground wires and provide lengths for each type.

Be able to specify a pressure drop in the ductwork that changes based upon the airflow in the ductwork.

We currently allow you to lock a specific pressure drop but it does not change as the design changes. Instead lock an equivalent duct length or something similar that would change based upon the airflow.

In the diffuser definition dialog box, designate whether it is a 1W, 2W, 3W or 4W diffuser, then attach that number of arrows. When placing the diffuser, allow the user to rotate the diffuser to align the appropriate air flow direction.

Be able to custom the wire callouts used for feeders and branch circuits.

Create feeders with a 5th wire (dedicated neutral) for computer/technology panels. These are typically routed to "K-Rated" dry-type transformers.

Be able to customize the "N" and "G" label in feeder callouts to different text. Likely you would change it to "NEUTRAL" and "GROUND", but give you the option to choose whatever you would like.
