How to Use Duct Handles in New Revit 2019 Features
When you select a duct segment in the view, multiple handles will appear. These handles allow you to adjust the size, length, elevation, and slope of the duct segment. Note: The slope of the pipeline network is only applied during routing. You cannot apply slope to the entire duct system through the slope editor. The length of the duct segment is shown as a temporary dimension at its midpoint.
The elevation at both ends of the duct segment is displayed near the connectors at each end.
You can drag duct segments and access a context menu by right-clicking on them.
Use the option to convert temporary dimensions into permanent ones. For more information, please refer to the temporary dimension annotation.
The slope direction of diagonal ducts is indicated by a slope value displayed at the center of the duct. This value represents the slope height-to-length ratio, angle, or percentage, depending on the project’s unit settings and HVAC regulations defined in the “Slope” parameters dialog box.
Dimension control handles allow you to select ducts in the drawing area, revealing duct controls and offset values.
To adjust the length, click the temporary length control above the duct segment, enter the desired length, and press Enter.
Elevation controls can be used to display duct controls and offset values by selecting ducts in the drawing area.
Click on the elevation control at each end of the duct segment, enter the elevation value, and press Enter.
If you enter different elevation values for each end of the duct segment, a slope will be applied across the segment.
Slope controls also allow you to select ducts in the drawing area to view duct controls and offset values.
Click the elevation control on one end of the duct, enter an offset value to specify an elevation higher or lower than the other end, and press Enter.
Use the slope control at the midpoint near the reference endpoint to indicate the slope direction, pointing toward the reference endpoint of the duct. If the slope value changes, the reference endpoint maintains its current elevation. The slope control value at the duct’s midpoint represents the slope height-to-length ratio, angle, or percentage based on the project units and HVAC regulations defined in the “Slope” parameters dialog box.
Click on the angle displayed at the midpoint of the duct.
This angle will flip to point toward the opposite end of the duct.
To set an absolute slope, click on the slope value at the midpoint of the duct, enter the desired slope value, and press Enter.
The input represents the absolute angle, slope length, height, or gradient of the pipeline, depending on the project units and the settings in the “Slope display” parameters dialog box.
