Change Connection Type

The Change Connection Type command is used to change the settings that are used when a diffuser connection is made. These settings affect newly inserted diffuser connections only. Diffuser connections that are made before you make changes are not affected. You have to manually change those ducts using the Query Duct command.

These values can also be set in the Options->Diffuser Connections section.

To change the default settings for diffuser connections, go to

DM HVAC->Diffuser Connections->Change Connection Type

Default Diffuser Connection Settings Dialog Box
