by showing velocity and PD/100ft on a check layer, engineers could check work and easily scan and review a job for errors.

Many breaker panels of old and of new has the ability to put a single, two, or three pole breaker in that takes twice as many spaces as normal. Example is I have a panel I have to represent that has a 2 pole breaker that takes position 36-38 and 40-42. It also has a 3 pole breaker in it that take 24-26,28-30,32-34. I have no way of circuiting the device and still have it on phase A, B, and C.

Often, I need to "start over" on a panel that I've assigned fixed loads. It would be handy to have a button that would clear every fixed load on the panel. Or even be able to select several circuits and clear those circuit's fixed loads.

When inserting fittings or piping the software will go through a regeneration process after each item is inserted. When files are small this is not a big deal. On large projects there is a noticeable delay and the software zooms out to the extents and then back into the area you are working on. Rather than do this on every change, include an option to only do this when the drawing is saved (and possibly when the drawing is opened).

Be able to sort schedules by different fields instead of just the default field.

In the various DM schedules (light fixtures, receptacles, diffuser, etc), add the option to link the entry to a PDF file. The PDF could be opened from the schedule, or there could be an option to include it as a hyperlink on the device so it can be opened from the AutoCAD drawing.

Be able to change the size of the arc-flash labels to fit a specific size.

Be able to show new and existing circuits on different layers in a panel schedule. The existing circuits would be on a lighter layer and the new circuits would be on a darker layer. The rest of the schedule could be on either the new or existing layer.

We need a way to link two family instances together so that when you update one of the instances it updates the other.

Add leader for duct text like it does when you add a grille, diffuser, or light fixture

Add features to support PV design, such as inverters, combiners, and a string calculator.

We can assign layers based on one-line (panel) or circuit or devices however not all parts of circuit are on the same layer. I may run some in the slab and some in the walls. Having the ability toi use the manual loop tool to change the layer system would be helpful. Also having the ability to assign a device to multiple layers would be helpful as well.

Or have some of the loops new and some existing.

When you generate a one-line diagram, if you have panels that have a vertical bus, their branch breakers end up at the bottom of the bus and are vertical. The look like main breakers--not branch breakers. A work around for this is for every vertical bus panel, generate a riser diagram starting with that panel. Even this work around is not perfect, as you have to resize the vertical bus and fiddle with the branch breaker.

Be able to swap circuits in Revit like you can using the "Move Circuit" command in DM Electrical for AutoCAD.

SIngle button to change from IP to SI in a drawing.

When printing load calculations, have a Select All/Unselect All check box. It's a bit tedious to do manually.

Modify design load calculations to more accurately size/select VAV boxes. The revised calculations would take into account the heat required to overcome the additional air supplied to the VAV box that is over and above the minimum required in the heating calculations. This will help since the additional air is typically at 55 degrees and will actually add heat load to the space in addition to that required by the envelope and minimum supply air. In some cases this can be a significant load.
