Add an option to automatically draw a hatch over the ductwork in 2D. Have the hatch be controlled by the type of duct (return vs supply) and layer system (new vs existing).38 votes
This feature will be included in DM HVAC 7.2.
Extract duct sizes and quantities from the HVAC database.
We're not exactly sure how this should work, so if you vote for this, leave a comment letting us know what information you would like displayed.21 votes
A final version of this, including fitting counts, will be included in DM HVAC 7.3.
Add duct top and bottom elevation tags based on the duct elevation and height. Tag would be turned on/off like duct size labels.19 votes
I’ve been waiting for a feature like this—this is something that is implemented and included in the next release of the DM HVAC. Thanks for the suggestion, now you can go spend your votes on other ideas!
This will be included in DM HVAC 7.3.
Specify a minimum size for ductwork when automatically sized.16 votes
This is completed for DM HVAC 7.2. It is implemented as a project-wide option. You cannot have different minimums for different duct sections or types. If you need anything more complicated like that, let us know.
Make a color shaded zone map simlar to load map.14 votes
This is completed for DM HVAC 7.2.
Provide option to show the dimensions for the exterior lining on the duct work.12 votes
See the “Duct Label Format Codes” section in our user manual for instructions on how to add exterior duct sizes to your plans.
Grocery stores include open refrigeration cases. These loads need to be subtracted from the cooling load and added to the heating load. Using a negative equipment load works for the cooling load, but not the heating load.
Make it so that a negative equipment load is added to the heating load.10 votes
This will be included in Design Master HVAC 7.1.
Make it so that arrowheads point in the direction of airflow in ducts.8 votes
This will be included in DM HVAC 7.0.
Omit the line that appears on only one side of a transparent duct section. Simply make the duct section transparent and allow the user to insert symbols as desired.7 votes
We have added this as an option for DM HVAC 7.0.
Be able to turn diffuser tags on and off for specific diffusers.6 votes
This feature is completed and will be included in DM HVAC 7.1.
This will be included in DM HVAC 7.2.
Add an option to size ducts to odd sizes for certain small ducts (5", 7", 9").5 votes
This is completed for DM HVAC 7.1. It is implemented as a project-wide option. You cannot have some systems size to odd duct sizes and others not size to them. If you need anything more complicated like that, let us know.
Provide a 'demolition' layer system option in addition to the 'new' & 'existing' layer options.3 votes
You can add new layer systems using the DM HVAC→Customization→Layers commands. See this support post for how to make dashed ductwork. It requires a few extra steps because of how we do hidden lines.
It could be useful if there was a Load Calculation Map which indicated when a room peaked in cooling. Perhaps two maps, time of day and which month. It may be useful when determining the zoning.3 votes
This is implemented in DM HVAC 7.2.
Have the option to assign a fixed Outside Air CFM to a zone. This will help address over-ventilation to maintain positive building pressure
Have the option to assign a fixed Outside Air CFM to a zone. This will help address zones that need over-ventilation to maintain a positive building pressure.3 votes
This is completed for DM HVAC 7.3.
Make it so that in the master configuration a user can preset which columns and labels they would like and in the order in which they are displayed. That way they are preset every time and would have save time setting up from project to project3 votes
This feature already exists. See the comments for instructions on how to use it.
Implemented for DM HVAC 7.2.8. This will be included in the next patch that is sent out to everyone.
Provide 'hot keys' for pop up dialog box.
Example: On the Duct Calculations box you could use the following.
C for Calculate CFM
D for Calculate CFM and Size Ducts
P for Calculate CFM, Size Ducts, and Calculate Pressure3 votes
Completed and will be included in DM HVAC 7.3.21.
We are having issues with permits using the ASHRAE Ventilation calculation because DM is using the calculated CFMs instead of actual CFMs on plans. We are having to tweak all the load inputs and use minimum air flows to spit out correct CFMs in ventilation calculation. The loads have actual loads print out, so maybe this is an easy fix.2 votes
This will be included in DM HVAC 7.2.
