Corridor Rollover

I am working in the rollover parameters and have found that a non-material(Dead/Dummy)node, when given parameters, does not transform. If I add it to a material layer it works fine. Is there reason or method to this madness? The node was created using the requisite offset/slope instr. Curious only.


The rollover is a computation of the slope change between two surface elements - a single point that has no surface element attached to it has no slope so it cannot compute a rollover value.


Copy that; what I assumed is that as dead nodes will translate over the superelevation instruction the rollover would follow suit. I like to create non-material nodes to reflect finish features and follow with a connect instruction. It took me a minute and a scan of your rollover walkthrough to see that it just don’t work that way - rollover that is.
