I have created a long capsule shape and I want a large number of arches to be spaced along it. The capsule shape bends along both the y and z axis, but all the arches should be aligned to the x axis with no rotation.
With dupliframes I got them to follow the shape of the capsule, but because it bends, while they are all oriented along the x axis, they weren't as wide as they should be at the far end. It doesn't seem to be a tool where I can add something on to also scale the x axis of the arches further along the curve. With an array modifier set to fit curve they turn to align with the curve.In that setup I could use an empty to scale the ones further down, but only if the arches can be made to align the right way.
The arches should align with the green highlighted arches. Is there a way to do this? Otherwise I think I'll break the curve into sections and create an arch with the right dimensions for each one, and an array for each. The structure is very large, there will be something like 600 arches, so it makes a difference.
