Longplot reverse chainage

Post by Jacinta McArdle »

Hi
I am trying to display my longplot from CH2000 to CH0, instead of CH0 to CH2000 as is usual.
Can anyone help please

Why?

If the chainages are irrelevant you could reverse the primary string and the longplot will reverse. Alternatively you could plot to a model and then apply a factor of negative 1 to reverse the image but that might screw with your text. Not sure if you could do something with chainage equalities.

set your Super_alignment start chainage to -2000
(actually you can change the chainage mode to END_POINT and set that to zero, or pick a control point so it doesnt keep moving on you)

ignore the sign on your plots or create chainage equalities
