Create an "Edit Multiple" command to works on all types of devices. Include only attributes that are common to all types of devices: layer system, elevation.

When connecting a new waste pipe to an existing pipe, draw the chamfer between the two using the new layer system (not the existing layer system as it currently does).

Would be great to be able to copy all piping, including risers to other drawings. Even if you had the option to change risers to pipe I think it would be helpful and save time from having to chase down and draw all the risers a second time.

Right now, one has to edit all the blocks of a panel schedule in order to simply change the font. There should be a way to set the preferred font for all these schedules. If there is a way, I don't know about it. When I first set up DM 10 years or so ago, I do not remember having to change every block, but it's been so long ago...

Be able to show conduits feeder runs on their own layer with up and down riser symbols. Then be able to create a conduit schedule.

Add new column to the equipment schedule that would display the length of the branch circuit.

Often when circuiting I find the location DM puts the label is very poor. It would be nice if after inserting the circuit I could move the circuit text without having to stop the circuiting action, move the text, then start the circuiting action again.

When defining rooms, it is often difficult to determine which rooms have been defined and which have not, if an area gets surrounded. Adding a hatch pattern on its own layer would make it much easier to determine if you've included all room definition areas.

Label homeruns using feeder IDs like those used in the one-line diagram instead of full text wire callouts.

HVAC diffusers have air flow patterns much like light fixtures have photometric patterns.

Air Diffuser manufacturers supply the pattern shapes and provide the distances in feet for airflow velocities at 150FPM, 100FPM and 50FPM for heating and cooling.

Is there a way you can give the DM user the ability to insert their own airflow pattern (through a formatted file input) with contour lines similar to DM photo metrics?

This would be DM's start into Computational Fluid Dynamics.

When a dialog box is moved, remember the location so that the next time it is opened, it is displayed in the same location.

Be able to easily mirror plumbing plans. Risers that extend to multiple floors cause problems for the mirror command.

It would be a great tool if we can have the ability to import model information from Revit drawings which are done by architects. A simple feature would be importing the rooms. This would speed up the process and make designs happen faster.

As the word of this software is increasing in Canada, it would be a good idea to have the capabilities of incorporating the Canadian Electrical Code into Design Master.

Weight of ducts in HVAC Takeoffs provide a very simple way to estimate cost of projects.

Or, add an option to calculate square feet of sheet metal ductwork.

Remove "DM HVAC", "DM Elec", and "DM Plumb" from AutoCAD window titlebar.

Allow for equipment schedules to be created by use, such as chiller, air handlers, pumps, etc. The schedule would be populated with equipment that is drawn by DM equipment command

Make possible not only the easy DM insertion of these devices onto the lighting plan but also the ability to account for these in the panel schedule and load calculations.

Improve the "Copy and Increment" command to work across drawings. Make it easier to move everything from one panel to a different panel on the copied devices.

Add a check box to set the voltage for a building. If a building is 120/240, then checking a box will set the default for panels, equipment, etc to 120/240v instead of 120/2083p4w.
