Sine Error

Hello all,

I have been stuck for some time with a design of mine and I suspect there is perhaps a bug here - or perhaps there is something wrong with my maths...

I have two lines that are mapped using a sine function - one floating above the other. One is however an inverse function of the other.

When I try to sweep along these paths - the resultant geometry is misaligned in the sense that one of the sweeps is shorter than the other. Is this something wrong within grasshopper that is causing this behavior or whether it is me misusing the components that is leading to these results?

I have attached the appropriate definition.

Thanks,

Sash

I don't know either. The amount of shortcoming differs as the rotational angle differs. In fact it seems as though the sweep only goes as far as the projection of the square start/end point onto the rail.

If I bake the curves and perform the sweep in Rhino I get the correct result.

I'm not sure what to suggest except to generate more sweep profiles.
