   The New Stub Pole option is only available if the currently selected pole does not already have an adjacent pole connected to it.

9. Enter values for the attachment pole:
   • Existing Pole
     1. Select the existing adjacent pole in the Type field. Take care to choose the correct pole as poles in the main profile will also be included in the list of available poles.  
     2. Enter the attachment height. OHDA outlines the field in red to signal an input error if the Attachment Height is greater than the pole height.
   • New Stub Pole
     1. Selecting New Stub Pole adds a potential pole to the canvas shaded in blue and creates a secondary profile.
     2. Set the values for the new pole in the Pole and Line Angle sections. See the add adjacent pole section for more details. 
10. Click Create. The guying is added to the canvas. If an adjacent pole was created, it remains on the Profile view canvas as a blue dotted outline and shaded blue in the 3D view. 
11. Click Calculate to analyze the updated scenario. If a stub pole was created, it is added to the scenario in a new profile with the blue shading and outline removed.

      2. Enter the attachment height. OHDA outlines the field in red to signal an input error if the Attachment Height is greater than the pole height.
    • New Stub Pole
      1. Selecting New Stub Pole creates a secondary profile and adds a potential pole to the Profile view canvas outlined in a blue dotted line.
      2. Set the values for the new pole in the Pole and Line Angle sections. See the add adjacent pole section for more details.
12. Click Create. The guying is added to the canvas.
13. Click Calculate to analyze the updated scenario.

Follow these steps to edit guying in a scenario:

1. On the Poles tab, select the pole with the guy you want to edit attached.
2. In the Components list of the currently selected pole, double-click the guy you want to target for editing. Alternatively, you can double-click the guy to edit directly in the 3D view canvas. This opens the Edit Guy form.

   Arm guying is associated with its attached assemblies, so you must expand the assembly's list of attachments in the pole's Components list to select.

3. Edit values as needed. Values that cannot be edited are disabled.
4. Click Calculate to analyze the updated scenario.

Click the red X next to the guying you want to delete in the Components list on the Poles tab. The guying is immediately removed from the canvas.

Any anchors associated with the deleted guying will turn red in the Poles tab but will remain on the canvas. The abandoned anchors must be deleted or connected to new guying before you can analyze a scenario.

Arm guying is associated with its attached assemblies, so you must expand the assembly's list of attachments in the pole's Components list to delete.

OHDA assumes that forces spread across multiple guy wires attached to the same pole in any configuration are equal.
