Burak Korkmaz 0 Report post Posted March 17, 2017 Hi,I would like to find the angle between two arbitrary lines.The plane in which curves positioned is rotated in x,y and z axis simultaneously.Please refer to the image that I've attached. The red curves are the lines I am mentioning. Magenta line is the normal to the plane.Best Regards,Burak Share this post Link to post Share on other sites
Mr. Klaus Straka 0 Report post Posted March 19, 2017 Hi Burak, you can use the tangent vectors of the two lines to calculate the angle by means of the dot product. I attached a small example. Hope this helps. Cheers,Klaus calcAngle.fdbc Share this post Link to post Share on other sites
