I did this previously with a spline at each floor level and a 2SArray set to 1 floor height, these splines were segmented and given ID for specific facade units, the seperate colours were controlled by 3 seperate Railclone objects with different materials assigned. The different building height were controlled just by copying up the splines by the number of floors required for each block.
I'm sure there must be a neater way to do this, need to be able to control the heights to specific value, and the colours. Can someone give me a nudge as to a better way of doing it? Can the height of 2SArrays be controlled by some parameter on the base object? Either that or I think maybe I could at least link each RCobject to a master style, so I'm only editing one object?
Any thoughts on best practice appreciated.
