So I want to draw a line of pseudo-3D boxes with a changing amount of "segments" of constant width (e.g. a box of 3 segments of 60p width, 180p in all, and one of 6 segments of 60p width, 360p in all). The depth of the boxes should be the same, so they align nicely.
Failed example (I want the z-angles of the boxes to be parallel, so I can string up any amount of these boxes in a row without it looking odd):
So far, I can only manage something like this, and my attempts to correct the viewing angle distort more than help.
To be honest, I've colored the first 3D-box and copied the others from it to save me the hassle of deleting unused areas and re-coloring each time, so perhaps the answer is "Use independent boxes and adjust the vanishing points manually", but if there's a way to set the angle between to adjacent segments of a path, it would be a lot more comfortable. Does this exist? Alternatively, am I missing an obvious other way to achieve what I want?
