Help needed

I would really appreciate a little help with my grasshopper file...

1.) The original red colour that you get from your grasshopper components in Rhino has now gone to this see-through red that makes my rhino file look very confusing. How do I return it to the original red colour?

2.) I have coloured in the base rectangles of my houses in green and I have a long blue rectangle that I have created for my river and I would really like them not to overlap, I have used several region trim and even attempted several boolean components and nothing seems to work. How do I make my green rectangles not overlap my river?

3.) When I make the river wider, some of the red houses are not removed or that become distorted... help?

I think that covers all my faults.... *embarrassed*

I would be very thankful for however little help someone is willing to provide.

1) the default material of GH previews is ghosted red and green. If you had a solid look, that usually means you were displaying multiple instances of the same geometry. Each instance makes the look more solid and dark.

2) and 3) made some cleanup... could be optimized more

It's always a good idea to update GH.

You need the current SR for Rhino 4. You can download it here: Rhino 4 SR9

Oh, ok.. to be honest, I didn't check up on your post while trying to fix your definition. Since your def. was names "new york grid", I totally accepted the river to behave like the the Broadway does on the grid of Manhattan.

You are dispatching the base points for your grid squares based on a tatic slider. This already works to kill all squares close to the river. I made the threshold be half of your rivers width plus half the diagonal of the grid square. This works well for a nearly diagonal river but cuts a wider corridor for angles close to parallel to the streets. While this is not ideal, it's fast and has no inpact on the rest of your def.

You could dispatch at this place checking for intersection of grid square with river footprint... but right now it's too late for me to figure out how how to test for null items. You'd need this test after the intersection of (grafted) grid rects with river to keep all the curves, that do not intersect with the river and thus return null.
