To remove an individual wire point at a structure, open the 'Wire Manager' from the Linear Draft toolbar.
The 'Wire Manager' form will be displayed.
Select the wire, from the 'Selected Wire' drop-down menu, that contains the wire point that you want to remove.
The wire point will be associated with a structure. Locate the structure from the 'Structures' section of the form and click 'Delete'.
This will remove the structure from the list and the graphical elements of the wire point will be removed from your model. The structure will remain, only now without the equipment.
The image below shows an example of a structure with its wire point removed.
N.b. The structures immediately before and after have not been affected and the catenary wires will bypass the structure from which you have just deleted it from.
