Igor 2 Posted March 16, 2017 I have curve from external Software and I must cut it at very special position. Is there a method how I can find point that is 90 degrees to given plane? I did add Tangent to curve with polyframe SOP but how to find special position? Thank you in advance! Share this post Link to post Share on other sites
eetu 526 Posted March 16, 2017 (edited) Wouldn't that be when the tangent on the curve matches the normal of the plane? Edited March 16, 2017 by eetu Share this post Link to post Share on other sites
Igor 2 Posted March 16, 2017 Thank you eetu! I think you are right but how to find exact Position? Share this post Link to post Share on other sites
petz 431 Posted March 19, 2017 well, there are many different ways of doing it. the crude one is to just recursively sample the curve and search for the point with the smallest deviation angle. this should what works for any case. the more elegant method however, would be to use a polynomial and solve it for the position on the curve at which the angle deviation is 0. hth. petz curve_find_point.hipnc 4 Share this post Link to post Share on other sites
