Add/remove Unions

Add/Remove Unions (Previously Place Coupling)

Once again, eVolve has added another time-saving feature. Users can now draw conduit runs without fittings, using factory elbows, and at any time click a button to place couplings all along the selected run(s) at chosen increments. This feature can also be used to create bulk offsets by placing a group of Auto Couplings and changing them to offsets afterwards.

The Conduit Couplings Configuration Window

NOTE: The Add/Remove Unions' predefined selection filter can be modified via the Selection Configuration. Please see the link in the Relevant Articles below.

Place Union radio button panel
  • Entire Path - places unions along the entire run.
  • Change of Direction - places unions from the defined starting point and direction until the direction changes, like an elbow, tee, cross, etc.
  • Single Location - allows users to point and click to place a union along the run.
  • Spacing - used to specify the spacing between unions. The default spacing is 10’ - 0".
  • Minimum Length - if the length of the last straight in the run exceeds the Spacing + Minimum Length, then the union is moved back to ensure the last straight maintains the defined minimum length. For example, if the last straight section is 10' - 6" and the defined spacing is 10' - 0", then the union is placed at 9' 6" instead of 10' - 0" to maintain a 1' - 0" minimum length at the end of the run.

  • Entire Path - removes all unions along the entire conduit run
  • Change of Direction - removes all unions from the defined starting point and direction until the direction changes, like an elbow, tee, cross, etc.


Using the Auto Coupling Feature

  1. From the eVolve Electrical Ribbon, in the Conduit panel, click the Auto Coupling button
  2. From the active Project View, select the conduit run/s to add couplings to
  3. Click Finish
  4. When the Conduit Couplings Configuration window appears, select a Placement Mode, the desired coupling Spacing, and click OK.
  5. In the active Project View, click toward the left or right of the view to show which direction to implement the change. (If not Entire Path)

TIP: When modeling with eVolve Electricals advanced conduit tools, such as optimize bends and auto-couplings, we recommend using the following workflow:

  1. Model conduit runs utilizing our smart bend families. (Without adjusting them)
  2. Use Align Conduit when necessary for conduit spacing
  3. Optimize the bends using Consume Selected End and/or Consume Adjacent Ends commands and make any adjustments
  4. Use Align Couplings to align the bend couplings
  5. Use Place Couplings to place couplings along the run (We recommend using the "Change of Direction" option when using this workflow and using steps 2-5 section by section)
