You can draw a duct run that is offset at a specified distance from existing geometry, such as from a wall in a referenced drawing. The geometry can be AutoCAD lines or blocks, AutoCAD MEP 2024 toolset building objects, or AutoCAD MEP 2024 toolset objects, and the geometry can exist in a reference drawing. You can select points on the geometry using AutoCAD MEP 2024 toolset snaps.
- Add a duct and begin a duct run as explained in Drawing a Duct Run.
- In the Properties palette Placement
Justification, specify the offset.
To... then... offset the new run at a horizontal distance (X or Y direction) from the geometry; the geometry and duct run are at the same elevation for Horizontal, specify a value for Offset. To offset the new run in a positive X or Y direction from the existing geometry, enter a positive value. To offset in a negative X or Y direction, enter a negative value. offset the new run at a vertical distance from the geometry; both have the same X-Y dimensions, but are at different elevations for Vertical, specify a value for Offset. To offset the new run in a positive Z direction from the geometry, enter a positive value. To offset in a negative Z direction, enter a negative value. - In the drawing, select a point on the geometry, using object or Offsetting Duct From Existing Geometry snaps.
- Continue selecting points along the geometry.
