To place a pole with construction, but no cables we do as follows:

  1. Click on the pole tool and place down the desired pole at desired location
  2. Click 'Add assembly' under the Attach Points heading in the properties pane 
  3. Once Add Assembly has been clicked, click on construction to make the crossarm
  4. Then model the construction and non structural components as desired. Note that multiple constructions/non structural components can be added to a single pole however, each time a different construction is desired a new construction must be made by copying the default no cable construction and editing that.
