Revit 2020
Windows 10
I am trying to insert a road into a site I created in Massing and Site via the Stedesigner addon for Revit 2020. I have created the copy topo surface using "Set Base Toposurface". When I attempt to insert a road using either predrawn reference line or drawn line I get the message in a Windows 10 error box "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" Screenshot attached.
Can anyone advise on how to resolve this error. I havent yet tried removing the site designer addon but that may be a fix although I suspect on reinstall it would pick up whatever data is causing the current problem?
Sure hope to hear from someone.
