Creates duct transitions for possible combinations of change to shape, size, and orientation.
The contents of the ribbon depend on the feature that you select.
Properties
Opens the Transition Settings dialog box with properties for the inserted transition feature. For more information, see Duct Transition Feature Properties Dialog Box.
Start Transition
Click to identify the start point of the transition. If you do not define a starting point, the software uses the current location of the object as the starting point.
Offset Transition
Click to identify the offset location for the transition.
Finish
Ends the placement of the transition feature. Click this button after you are satisfied with the editing that you have completed.
Plane
Plan Plane
Defines the work surface as the XY plane at the depth of the active end. You also can press CTRL+1 to select this option.
Elevation Plane: East-West ( Z Plane: X-Axis)
Defines the work surface as the XZ plane. You also can press CTRL+2 to select this option.
Elevation Plane: North-South ( Z Plane: Y-Axis)
Defines the work surface as the YZ plane. You also can press CTRL+3 to select this option.
Plane by Turn/Branch
Defines the work surface as the plane defined by an existing turn or branch. You select the turn or branch to set the plane. You also can press CTRL+4 to select this option.
Plane by Three Points
Defines the work surface using three points that you define. You also can press CTRL+5 to select this option.
No Plane
Clears any work surfaces. The software does not project points that you place to any plane. You also can press CTRL+6 to select this option.
Width Plane
Defines the work surface along the width of the duct. This option is available when Shape is defined as Rectangle or Flat Oval, and Type is defined as Turn or Miter Turn.
Depth Plane
Defines the work surface along the depth of the duct. This option is available when Shape is defined as Rectangle or Flat Oval, and Type is defined as Turn or Miter Turn.
Run
Defines the name of the duct run associated with the transition. If you select New Duct Run, the New Duct Run dialog box opens. The New/Continue Run option automatically activates the duct run of the selected feature.
Type
Defines the type of transition feature. Options include Straight Parallel, Straight Slanted, Turn, and Miter Turn.
Shape
Defines the shape of the duct. You can change size and orientation, as needed. Options include Rectangle, Round, and Flat Oval.
Width
Defines the width of the new rectangular or flat oval cross sections. Values stored in the reference data determine the list of options. Also, you can enter an amount for the width.
Depth
Defines the depth of the transition feature. The Depth box displays for rectangular and flat oval features. Values stored in the reference data determine the list of options. Also, you can enter an amount for the depth but the amount must be less than or equal to the width.
Radius
Defines the corner radius of the feature. The Radius box displays only for rectangular transitions. Values stored in the reference data determine the list of options. Also, you can enter an amount for the radius.
Diameter
Defines the diameter for a circular transition feature.
Orientation
Defines the orientation of the duct run by specifying the angle between the local axis of the duct run and the width axis. A value of 0 results in a duct run with the width horizontal and the depth vertical. A value of 90 degrees results in the width vertical and the depth horizontal. The value for an angle ranges from 0 to 360 degrees.
Align
Defines the transition alignment. Options include Align Centerline, Align Top Left, Align Top Right, Align Bottom Right, Align Bottom Left, Align Top Center, Align Right Center, Align Bottom Center, Align Left Center, and Not Aligned.
Length
Defines the length of the transition.
Throat Radius
Defines the radius of the transition throat. The Throat Radius box displays only if the Type option is set to Turn.
Lock
Turns on or off the lock for the angle constraint. The icons show the status of the lock (on or off).
Angle
Defines the angle of the turn transition and is available for turn and miter turn transitions.
Miters
Defines the number of miters for the miter turn transition feature. The number of miters returns to the default value whenever you modify the angle, either directly or indirectly. The value can range from 1 to 99.
