Follow these steps to swap an assembly:

1. Click the Swap button just below the assembly name. This will open the Swap Assembly form.
2. Select a new assembly from the drop-down list. 

   OHDA will only display valid assemblies for swapping. Assemblies must: Have enough pins or insulators to support the number of cables strung to the current assembly. For example, if an assembly currently supports three cables, then you will only see swap options that have three or more pins or insulators. Not have a pole top bracket, unless the assembly being swapped is the top-most assembly. Not be a vertical assembly if swapping the sub-assembly of a line and buck.

3. Select Apply to All Poles to have the change affect all poles in the profile.

   The Apply to All Poles selection works with assemblies on the same vertical level. Consequently, you may have an instance where a conductor changes assembly levels in the scenario. In this instance, Apply to All Poles will not swap all assemblies that hold the conductor.

   If one pole in the scenario violates a swapping rule, then the assembly will not be available to swap on all poles.

4. Click the Swap button. The Calculate button turns red and a refresh calculations warning message is displayed at the top of the canvas. Or, click Cancel to exit the Swap Assembly form without making changes.
5. Click the Calculate button to analyze the new scenario.

Edit Assembly form

Set the Distance from Upper Level field to adjust the distance of the assembly from the pole top or assembly above. For multiple-bracket vertical assemblies, the distance from upper level value for that assembly is measured from the top-most bracket. The distance from upper level value for lower assemblies use the bottom-most bracket as a starting point.

Click and hold the red arrow on top of the assembly. Move the mouse up and down to adjust the height. Release mouse button to set. Moving a multiple-bracket vertical assembly will move all insulators

A macro assembly (line and buck) is designed to handle extreme angles in a profile. If one is available in the Assembly list, you can select it in the Swap Assembly form to accommodate profiles with line angles that produce too great a force for an inline assembly to handle.

Once you select a macro assembly and click Swap, the Swap Assembly form closes and an Edit Assembly form opens. The 3D view displays the new line and buck with both assemblies highlighted yellow. Cables are automatically distributed across the assemblies with jumpers added to continue the circuits.

You can set the angles of both assemblies individually on this form, or select the Auto Angle checkbox. Selecting Auto Angle will set the line and buck assemblies perpendicular to their respective incoming or outgoing conductors. Just as with inline assemblies, you can adjust the height of both cross arms in a macro assembly directly in the 3D canvas.

Swap Line with Buck

Press this button to swap the upper assembly with the lower one. You will notice a change only if the two assemblies are of different types.

Double-click an item associated with an assembly to open the item's edit form.

In 3D view you can target an assembly's component to edit by holding the Shift key and double-clicking the component on the canvas.

• Pin, Post, or Suspension - Set the Horizontal Offset from center either to the right or left. Select the type from the Spec drop-down list and click Update.
• Attachment Hardware - Select the Spec from the drop-down list. Click Update.

If a pin is paired, then both pins move the same distance when either is relocated.
