"okey, problem solved. It was for using MoveObject instead of CopyObject. In GH the transformations generate new independent objects but seems that doesn't work that way in Python. The translation vector was applied to the same point…"

Hi everyone.I've been doing a script with the Python modules of GH and after the last Rhino 5.0 update yesterday all rs.Distance orders have stopped working.I' ve written a simple distance between…Continue

Hello guys. I've been trying to generate a set of randomly twisted spirals around a curve with python but there's something strange about it. Basically is a set of division points of a initial curve with their respective lists of tangent and perpendicular vectors. I'm trying to rotate randomly this perpendicular vector around the tangent axis at each point and generate another point for the spiral curve. It's suposed to generate spirals around that first curve at a fixed distance (the lenght…See More

sometimes GH's tolerance of input parameters can be misleading."

Systemiq replied to David Andres's discussion Circles around a curve + DivideCurve : changes in orientationDavid Andres replied to David Andres's discussion Circles around a curve + DivideCurve : changes in orientation"Thanks for posting. The PerpFrame gets the same result. I've manage to do it using as you said CurveCp and Seam, with another reference curve to get always the lowest coord Z point. It does the work.
If anyone know a simpler way to do it…"
Hannes Löschke replied to David Andres's discussion Circles around a curve + DivideCurve : changes in orientation"The tangent vector isn't enough to define consitent frame (coordinate system). CNR guesses the plane on which to create the circle on fron the world coordinate system.
The PerpFrame constructs a perpendicular frame from tangent and curvature…"

Simple question that is driving me crazy, how can I avoid this to happen?The vectors are oriented in a single direction, but the circle is drawn with a different orientation depending on the vectors direction. I was doing this in Python in order to make several spirals around a curve but I'm blocked…See More
