Sweep many rails with single profile
9 Replies

I have a profile curve that i want to sweep across a series of curves.  I can't get anything to sweep unless the profile curve is oriented on the rail curve (making it impossible to sweep many curves…Continue

I'm trying to apply 5 attractors to a scene, but the only method i know for attractors is by the distance between 2 or 1 and a centre point. Why can't i just assign 5 points instead of one? Seems…Continue

"Thanks!  Worked like a charm.  One question, what is the "starting parameter" of a curve?  It worked regardless but this would be valuable to know."

"Here's the definition with some explanation. The reference point for the section curve was the center of the circle but it could be any point depending on what you want as a result.  I went with a symmetric example for simplicity. Chris"

"I deduced that top curve input is the profile curve and the battery beneath that holds the multiple rail curve inputs.  Can you please explain which points are used for the reference points?  Also, are there any other values set directly…"

Sweep many rails with single profile

I have a profile curve that i want to sweep across a series of curves.  I can't get anything to sweep unless the profile curve is oriented on the rail curve (making it impossible to sweep many curves at once).  I am sure I was able to achieve this in the past.  Could it be that the newer versions of Grasshopper have eliminated this?See More

"Thanks for the help, Manuel! All my points are on the same plane, so i am not sure what it will take the distance from? This seems promising but i cannot tell exactly what i am getting as my output (p)"
