Using AutoCAD MEP 2023 toolset snaps, you can automatically connect a new run anywhere along an existing duct segment or fitting. The fittings that are automatically inserted between the existing duct and the new duct are configured in the routing preference and duct layout preference.
- Open and configure the Properties palette, as explained in Drawing a Duct Run.
Starting a run
- Move the cursor over the end of the existing duct segment to display the duct end connector snap.
- Click the duct end connector to specify the start point of the new run.
The size and system for the new run matches the existing duct.
- In the Properties palette, specify a routing preference.
- To use a different size for the new run, specify a new size.
If you use a different size for the new run, a transition fitting is inserted to connect the new duct to the existing duct. If the duct layout preference is not configured with an appropriate transition fitting, you are prompted to choose a part.
- To use a different shape for the new run, specify a new shape for Shape.
If the duct layout preference is not configured with an appropriate transition fitting, you are prompted to choose a part.
- Continue specifying points to lay out the run.
Starting a run at a point along a duct segment
- Move the cursor over the existing duct segment to display the duct curve connector snap.
- Click the duct curve connector to specify the start point for the new run.
Based on the connection type configured in the duct layout preference, a takeoff or tee is inserted.
- Continue specifying points to lay out the run.
Ending a Run on an Existing Duct
- To connect a run to an existing segment, move the cursor over the existing duct segment to display the duct curve connector or duct end connector.
- Click the duct curve or duct end connector to specify the endpoint of the run and connect to the existing segment.
