Design Master Wish List

The current releases are DM Electrical RT 2.0, DM Electrical 8.6, DM HVAC 7.3, and DM Plumbing 4.1. We are not adding new features to these releases.

The next releases will be DM Electrical RT 2.1, DM Electrical 8.7, DM HVAC 7.4, and DM Plumbing 4.2 We are actively working on these release and using this wishlist to guide which features we implement. Features marked as "Planned" will be available in these releases.

  1. Diffuser Airflow Patterns

    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.

  3. please show velocity and PD/100ft

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

  4. HVAC Load Calc Graphics for Windows/Glass

    Provide a graphic for windows/glass located on walls so you can see easily and quickly figure out which windows have been entered into the load calculation.

    Additional idea: Make it a dynamic block so that when you change the width (using a grip) you can stretch the window to change the actual width. The width x height would display above this graphic.

  5. Automatically add Diffuser Arrows for 1W, 2W, 3W & 4W

    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.

  6. Equipment Schedules

    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

  8. Equipment in takeoffs

    Display equipment information in takeoffs. (Currently the equipment blocks are graphical only, mainly for 3D drafting).

  9. Provide Weight or Area of Ducts in Takeoffs

    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.

  10. Actual Tonnage for HVAC Equipment

    Add an option to specify the actual tonnage for HVAC equipment in the zone dialog. Use this value to display actual CFM / ton and other values.

  11. Duct Continuation

    There may already be an option (please inform me as I am not aware) for a 'duct continuation symbol/fitting'. Currently I have to go back and Pline a goofy looking thing to indicate continuations in the ductwork. Any thoughts?

  12. Use correct fittings

    The pressure drop calcs indicate the wrong fitting types in some cases. For example, a fitting that begins with "SD" stands for "Supply/Diameter" and "SR" stands for "Supply/Rectangular", etc. If you have a duct system that is all rectangular, there should not be any SD fittings indicated. Likewise for round systems, there should not be any SR fittings indicated.

  13. Dialog Boxes to View and Edit Load Calculation Settings for Entire Building at Once

    Currently to view the ventilation and load schedules the report is run and appears in an html file. If for instance the outside air % is too high I then have to exit the report go back into the rooms with the high percentage and manually overventilate.

    It would be great if there was a screen that combined all of the room information, areas, CFMs, etc. (similar to the load report) but this screen allowed you to manually modify the CFMs, system static pressure, outside air percentage, etc. and by doing this all of the room information is updated at…

  14. Modify design load calculations and output to accommodate VAV system selection

    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.

  15. Create training material for the HVAC section.

    The tutorial doesn't get into enough depth or cover everything, specifically the master schedule and project schedules and how they affect the project.

  16. Add Static Regain that balances duct system correctly

    Current Static Regain calculation does not seem to calc and size ducts to balance system. The static regain should balance the system where the ducts split.

  17. Provide Minumum air flow calculations

    If the minimum air flow is set in the calculation bases on a parameter such as air change rate, cfm/sq ft or a set cfm it would be nice to have that as a column in the calculation output.

  18. Import Ductwork from Past Project Databases

    Import ductwork and equipment from other databases. This facilitates additional projects at the same location. The thought is that if we can import the ductwork as existing from old projects, it would allow us to add/remove/modify ductwork much easier and quicker then re-drawing the existing ductwork from the previous project.

  20. Match Runout size to GRD Neck Size Automatically (without running CALC)

    Would you please consider an option to size the runout the same as the diffuser connection, without having to use the CALC function? That feature would be a big timesaver!
