Joining Hex Cell / Ngon Patched Surfaces

The above image shows the result of a grasshopper pattern made from a bunch of patched surfaces from a series of hexagonal polylines. They seem to be perfect until I was having trouble joining them together. From a closer look, the resulting patched surfaces are actually not perfectly touching each other. Does anyone have an idea of how to solve this? Below is the code.

I’ve found a solution to this and this is by manually patching the hexagonal closed curves one by one and do a bit of mirroring to speed up the job. So apparently there is a difference between how grasshopper patches and rhino patches because they are using the same hexagonal closed curves to patch. Or perhaps I’m just missing something in the gh parameters.
