Ductwork

The articles in this section provide helpful tips and tricks related to the Design Master HVAC ducts and diffusers that appear on your drawings.

📄️ How to Make Dashed Ductwork

You can set your ductwork to be drawn with dashed lines using the Layers customization command.

📄️ Removing Existing Diffusers from Schedule Quantity Counts

Existing diffusers can be excluded from schedules by creating a separate schedule entry and unchecking the Include in Schedule box.

📄️ Creating a Custom Diffuser Callout Block

Here are detailed instructions for creating a custom diffuser callout block and redefining the callout block in your projects.

📄️ Inserting Turning Vanes

Turning vanes can be inserted manually when you insert square elbow and wye fittings, or you can set them to be inserted on those fittings by default in the project customization options.

📄️ Inserting Eccentric Transitions

You can insert an eccentric transition in your ductwork by configuring the horizontal alignment for the duct centerline.

📄️ Changing Duct Offset in the Middle of a Duct Run

When changing the offset in the middle of a duct run, insert a transparent duct so the ductwork will be modeled correctly.

📄️ Labeling Ducts and Diffusers in Metric

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

📄️ 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.

📄️ Duct-Mounted Diffusers

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