"Depends on how your original points are organized. Posting your files might help with that. That said, it will come down to a clever combination of FlipMatrix and ShiftList."

sort points in triangle grid to create independent lists of parallel curves

I have a triangular grid and I want to interpolate curves through the points as illustrated in the screen shot so that I have three independent lists of parallel curves. Im having difficulty sorting the points in a way that would allow me to do this. Any ideas?…See More

Sphere tangent to surface at divided curve points

I want to be able to create spheres that are tangent to a 3d brep at given points along a curve on the brep (sort of like in the screenshot below). Any ideas on how to do this?See More

Series of numbers where each value increases by percentage of preceding value

I'm looking to create a series of numbers where each successive value increases by a percentage of the preceding value. So starting with 1.0 and increasing by ten percent, I get 1.1, 1.21,1.331 etc. Much like the series component, I would want three sliders, initial step value, percentage increase, and total number of values in series. Any help on this would be much appreciated.See More

BBX - Divide Curve - Vector Direction Problem

Hi -- I am solving an intersection event between a referenced Brep and parallel planar surfaces. I then divide the curves from the BBX to get the tangent vectors at each point. The problem that I'm having is that the vectors at the points on the top-most curve are pointing in the opposite direction from all of the other vectors, which looks like this:…See More
