For large sprawling duct systems it is difficult to monitor all the duct sizes that change. When you calculate and redraw a single branch, all the ducts are erased and redrawn. This makes it difficult to know which duct sizes changed and which stayed the same.

Add indoor point-by-point lighting calculations.

If there was a way to have the export of one line diagrams go to drafting views instead of populating external dwgs?

Calculate the load based upon the length and the remote transformers.

Be able to right click or slow-double-click on a room name in the Zone Tree or Floor Tree to be able to change it

Support drawings with metric base units.

Especially for waste and vent sizing, the conversion from fixture units to pipe sizing is standard for all cases for the UPC and IPC. Generating sizing charts for cold and hot water, automatically through a series of settings possibly, would be probably more difficult to implement but equally helpful to make sizing plumbing easier.

I have lighting reps ask me all the time for an excel spreadsheet of our luminaire schedule. It would be helpful to export our luminaire schedule into excel.

DM does not currently support more than one source on the Normal side of an ATS or the EM side of ATS, however larger I-2, I-3 occupancies generally have paralleled generators connected to a switchboard. This feature would avoid cumbersome work arounds.

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.

Be able to create plumbing and piping fixtures, similar to light fixture or receptacles in DM Electrical or diffusers in DM HVAC.

MV conductor insulation is much larger so you cannot get as many conductors inside a conduit. if you're using design master to calculate your feeder conduits it will be incorrect over 600v. I don't believe this is readily apparent now.

Add the ability to specify a prefix or suffix for panel callouts when inserting them on the drawing. For example, be able to label them NEW PANEL 'LA' rather than simple LA.

Also be able to replace the panel name with a different value in the circuit callout. This feature would be used when the panel name is very long.

Also be able to leave the panel name off entirely and list just the circuit number in the homerun label. This feature would be used when there is only one panel in an area.

Be able to draw loops between devices for low-voltage lines, for connecting items like sensors and power packs.

High-leg delta panels are always unbalanced. The balanced 3-phase amps we display is not a good number to use when sizing these panels. The connected amps by phase does not account for largest motor loads or continuous loads.

Add the ability to determine the amps by phase using calculated loads. The largest motor, lighting, and continuous loads would all be calculated at 125%. All other loads would be calculated at 100%.

Add outdoor point-by-point calculations for parking lot lighting.

When selecting conduit I want to be able to select the feeder as schedule 80 so that the only size option would be based on schedule 80. Then on another feeder I could select EMT for my circuits and the only option for auto sizing would be based on EMT. Finally, I would then have the option of adding the type to my one-lines and a conduit schedule.

Be able to change voltage of a completed project for 208V to 240V and keep everything connected and circuited.

Add an option to require a set number of spare breakers on every panel. The other breakers in the panel would be listed as spaces.
