Add some way to quickly change between tick mark configurations in the "Insert Tick Mark" command. Either templates that the user creates, or a set of commonly used configurations.

If you do vote for this, it would be helpful for you to leave a comment listing most common configuration of tick marks you use.

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

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.

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

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.

Add 3 more custom load types.

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.

When editing multiple devices, be able to select from a list in addition to being able to select from the drawing. Equipment currently works this way. Expand it to other types of devices.

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

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.

When a feeder neutral is doubled, DM simply adds a second neutral wire. NEC 310.10 does not allow this for wires less than 1/0. Update this calculation to correctly resize the wire when appropriate.

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.

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.)

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.

Add an "Edit Multiple" command for pipe risers.

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.

Create a ventilation schedule that corresponds to what is required by the IMC.

Be able to specify a custom description for the voltage on light fixtures when they are set to "Universal". Currently DM lists all the voltages that are used on the fixture. This feature would allow you to override that and specify custom text for the voltage in order to better match the manufacturer's cut sheet.

This command would be invoked from the panel circuiting dialog box, and would highlight all circuits fed from a particular panel.

Be able to create recurring meter banks and recurring panel instances that increment their numbers automatically. For apartment buildings with identical floors. Model one floor, then be able to reuse the model for the other floors.
