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.

Add an "Edit Multiple" command for pipe risers.

Convert existing ductwork and piping layer to demolition.

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 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.

Be able to automatically update the impedance in a wire based upon the conduit material type.

Currently you have to create a separate wire configuration for each conduit material type.

Be able to specify the fault at the upstream device, rather than at the current device. This feature would be useful when you want to specify the fault at the utility transformer but it is not included in the Revit model.

Set the available CFM for a piece of equipment. If this value changes, update the airflow assigned in the downstream ducts.

Be able to have labels set to right justified or bottom justified, rather than always being top-left justified. This way they will update correctly when the value changes during the design.

Add 3 more custom load types.

Similar to how you can right click to add leader lines when labeling diffusers, it would be helpful to be able to right click duct labels to rotate them instead of making this a two step process. Also, rotating it would remove the arrow that sometimes accompanies the duct label.

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

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.

Add support for calculating loads based upon NEC 630 Electric Welders.

After inserting a light fixture, prompt for the location of the light fixture callout. This feature exists for the callout style that is not directly linked to the fixture. The request is to make it work for callouts that are part of the fixture.

Add the ability for wire size callouts on the panel schedule to wrap if they get too long, similar to how circuit description wrap.

Be able to change the circuit a device is on and not remove the loops connected to it.

When a VAV zone has people diversity specified, update the zone airflow. Currently, the zone load is updated, but the airflow is not.

Add a button in the "Select block" dialog boxes to open the block customization dialog box.

When you create equipment, the information from the last piece of equipment is remembered and filled in. Add a "Reset to Defaults" button to the create equipment dialog box that would clear the information and reset it to its original state.
