Thank you, Lazur. I found a good choice of parameters in ’Parametric Curves...’ : -1.0 3.0 on -10.0 10.0 -10.0 10.0 200 off t/12+cos(t/4) sin(t/4) off off off These parameters give us an exact one cycle of spring. By using it and putting it along a path, I could draw a smooth spring curve as desired...

Thank you, Lazur. I could draw a spring by courtesy of you. My goal is to draw a spring along an arbitrary path. I cut one cycle of this spring, and by 'Path Effect Editor' -> '+Add' 'Pattern Along Path' put it along a path, then the generated image is as shown. I've adjusted this image: Fuse nearby...

Hi, I want to draw a spring(gluon) by 'Parametric Curve'. I clicked 'Create rectangles & squares' :tool_rectangle: and created a rectangle(square), and clicked 'Select & transform objects' :tool_selector: two times. First I followed Beenwu's method. http://gfif.udea.edu.co/web/tiki-index.php...
