Changing Duct Offset in the Middle of a Duct Run

Posted on January 28th, 2011. Last updated on October 29th, 2018.

Ductwork in Design Master HVAC can either be centered, flat on the left side, or flat on the right side. See Inserting Eccentric Transitions for more information.

When the offset changes in the middle of the ductwork, the ductwork will look like this:

To prevent this, insert a transparent duct at the break where the offset changes. The transparent duct centerline is drawn in red in the following example.

Duct-Mounted Diffusers

Design Master HVAC does not have a command specifically for inserting or connecting duct-mounted diffusers and grilles. However, you can approximate them by inserting the diffuser close to the duct to which it is mounted.

Ductwork Double Lines Are Overextended

If double lines are being drawn past where the duct centerline ends, you may need to straighten some of your ducts.

How to Hatch Ductwork

You can display hatches on ductwork using the Layers customization command.

Connecting Ducts Between Floors

Depending on whether your floors are on the same drawing or different drawings, you can connect ducts between them by either drawing a transparent duct or using the Insert Drawing to Drawing Connection command.

Labeling Ducts and Diffusers in Metric

You can set your duct and diffuser labels to metric in the customization options.

Loop in Ductwork Error

Design Master HVAC cannot calculate the CFM for ductwork loops. You can solve this by running the Coordinate Drawings and Database command if you have no loops on the drawing, removing the loop, or modeling the loop differently.
