How to correct Normals for DupliVerts? I have been trying to align objects along a curve only pointing along the Z-Axis. I found i could accomplish it using DupliVerts and checking rotation, but because the mesh only has two verts, it doesn't know where to point the objects.





I can fix the problem if i extrude the mesh upwards, but i don't want to do that because now i have two sets of mesh. 





Does anyone know how to force Blender to point the normals in one direction? Any help would be awesome!
Place the pillar at the beginning of the curve, be sure to apply rotation and scale (or at least have an alignment relative to the world or the object itself, locally)  :



Parent the pillar to the curve, and set dupli as frames (uncheck the speed button) :



For the curve, set it to path animation tunes the frame count (it will be the amount of pillars) and check 'follow'.



Now add a constraint to the pillar to 'limit rotation', and check the wanted axis (here Y). So the pillar will follow the curve without rotating around this axis.
