Would make sense to add a note field in the equipment connection creation form or in the circuiting form to tag individual breakers with specific requirements, possibly with a superscript which refers to a box of notes attached to the bottom of the schedule.

Add support for annotative scale factors for blocks and text. This would allow blocks and text to be the same size in different scaled viewports.

Add a Schedule of all blocks used in the project. This could be used a Symbol Legend for the Project.

Create a schedule of VAV boxes, similar to the diffuser schedule.

Insert the load calculation schedules on the drawing.

Be able to export building load information to eQuest or DOE2.2 using gbXML for energy modeling purposes, such as ASHRAE 90.1, LEED, and Title 24.

Premade blocks similar to what is used in both HVAC and Electrical could be inserted into the drawing with predefined fixture units. The fixture units would be stored into multiple headings with IPC and UPC fixture units. The connections would be there with predetermined heights as well.

Have a mask on all the text inserted with Design Master that will hide anything on the drawing behind it to make it easier to read.

implement Multi-Text search through out the menus.

So for example when searching through the Insert Receptacle menu and in my case we have several thousand pieces of equipment. if the equipment is called 'RX99S' instead of just allowing us to hit 'R' and starting us off at the beginning of the list of 'R' equipment allow us to type out 'RX99S' and design master go straight to the piece of equipment. this is a very simple change to the code in design master and would save tons of time on projects.

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?

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.

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

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

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