Tapered Fence?

[George]

I'm trying to recreate one of the attached fences (the taper would occur on a particular ID). The bottom height stays constant, and the top tapers down. How would I do this?

If there's no current solution, could I suggest adding the ability to set a morph amount on a per segment basis? That way I could have a morph on the left and right top corners of the wood paling, and set it according to distance along segment in an expression, etc.

Hi George,

You could achieve that effect by using a spline to define the top of the fence instead of the bottom. The using the equation (XSplineCoords.z/currentFenceSegmentHeight)*100 you calculate a scale value that will fit the fence segments between the spline and the RailClone object's position on the z axis as defined by it's pivot point. Using this technique it's possible to create not only fences with slopes but undulating curves and other shapes too 

Please see the attached file and screenshot for an example.

Hope that helps,

Paul

Brilliant! Although just to confirm, this wouldn't work if you wanted a non-constant height bottom, right?

Hi George,

You're correct, this would only work if the bottom of the fence is a constant height.

Thanks,

Paul
