Defining the Bend Angles of a Segment

You can define the bend angles of a segment without impacting the two adjacent segments directions using the Manage Angle without Network Impact command. The modification of these two bend angles can be driven by some constraints linked to the length of the segments, or to the direction. The minimum and maximum values of the angles are displayed, which enables you to choose a permitted value following the design of the route.


Before you begin: Open a product containing a route with two bends.
  1. Double-click a route.
    You switch to the HVAC 3D Part Design app and a yellow symbol appears on each node of the route.
  2. Click the middle of the segment for which you want to define the bend angles.
  3. On the context toolbar, click Manage Angle without Network Impact .
  4. In the Manage bend Angle Without Impact On Network dialog box, select one of the following modes:
    Mode Description Available Parameters Comments
    Angle and length You can modify both angles, only one angle or the length by locking or unlocking the bends. To lock or unlock the bends, click on the symbol in the 3D area. When the symbol is green, you can directly modify the angle value. When the symbol is red, the angle value is modified accordingly to the length modification of the adjacent segment.

    • Angle A
    • Angle B
    • Length of adjacent segment A
    • Length of adjacent segment B

    Note: You can set only two of the four parameters listed above.

    The two symbols are green: you can set both angles. You need to select one of the angle A or B in the dialog box to set it as main angle. The main angle drives the maximum and minimum value that the other angle can have. You can modify both angles only if they are in a different plane.

    One symbol is green and the other one is red: you can set only one of the two angles as well as the length between the bend angle with the red symbol and the previous node.

    Both symbols are red: you can only modify the lengths between one of the bend angles with the red symbol and the previous node .

    Straight length You can modify the length of the segment and one of the angle. Under Angle and Length, select the angle you want to modify and set a value. Under Straight Portion, you can choose to modify the straight length or the spool length.

    • Angle A or B
    • Length

    This mode is available if the bend angles are in a different plane.
    Minimum straight length You can modify only one of the two angles. The minimum straight length of the segment has the value of the straight length of the segment.

    • Angle A or B
    • Length

    This mode is available if the bend angles are in a different plane.
    Dry stacking The straight length is set to 0mm. - This mode is available only if twice the value of the bend radius is higher than the straight length between the two nodes.
    Vertical The segment is built to become parallel to the Z axis and all the spinners are disabled. - This mode is available if the vertical solution is possible.
    Horizontal The segment is built to become parallel to the X axis and all the spinners are disabled. - This mode is available if the horizontal solution is possible.

    A preview is available for each mode when a solution for the selected mode is possible. You can change the selected mode and its parameters until you find the right design.

    The length of the segment can be defined as straight length or spool length.

    Notes:
    • The modes are available in the list if the design allows this capability.
    • If one end of the segment is a branch port:
      • Manage Angle without Network Impact command is available for rigid or flexible branch.
      • Only Angle and length mode is available.
      • A double green arrow is displayed to let you choose on which segment you want to work.
  5. Click OK.
    The segment nodes move to the new position defined by the required inputs.
