Does anyone know how to delete "ghost" VPI's? They only show up when you toggle line markings, but they act as VPI's and are no able to be edited in the VPI editing window.

    Never heard of anything like this Jeff. Can you send me a line as a VCL file that has this issue and highlight those VPIs with a circle or something so I can look at them here?

    This was a question a coworker of mine had asked in our TBC group and he figured it out. 

     

    See response below.

     

    The circled node you see is an elevation point based on the Horizontal edit window. Selecting that horizontal segment and setting the elevation to "?" will remove that elevation node.

    i was looking at something else today and noticed that if you use the Vertical Control Offset / Slope that the VPIs are created and will let you step to them once created but do not display in the Show Line Markings or when you edit the Linestring. They also change from Offset / Slope (with Ref Line) to Elevation VPIs which I think is also incorrect as they should retain the parametric association I think (am checking with development), so maybe these could be the "Ghost VPIs" that you are referring to - however once highlighted I could edit one of them - but glad your colleague found the solution, thanks for letting me know
