Displace Mesh along Curve on single axis I am modeling bridges and want to use a curve to shape them. However I only want the vertices to move along a single axis (like Z).



With the Curve Modifier, the panels don't hang straight downwards.
Create a constant-offset array of a single mesh edge, crossways to the bridge-curve..
Set the arrayed edge's duplication to Dupliverts
Parent the vertical elements to the array of edges?




This might not suit .. there are other options, particles on placeholder planes, parenting with constraints..
