 Hi Rainer, The method Michael mentions is the way to go, here's a quick run-down for you and anyone else who's interested. Create a regular Helix, 'Draw curve > More > Helix' Draw a line (Green) perpendicular from the start of the Helix to the centre. Sweep the Green line along the Helix 'Construct > Sweep' and use 'Flat' in the Twist option drop down. Create a Sphere 'Draw Solid > Sphere' from the centre of the helix and use the end point of Helix for the size. Then use 'Construct > Curve > Isect' to create an intersection curve between the Sphere and Swept surface, and you have what I call a 'HeliSphere' Then have fun with it! Cheers ~Danny~

 Yeah Michael, I was happy with it too! The curve is good as is, but further refining with 'rebuild' and you get a nicer curve with evenly spaced control points. Cheers ~Danny~

 4084.6 In reply to 4084.3 Danny, How did you cut the curve perpendicular to the surface in the rendered example? Thanks, David

 4084.8 In reply to 4084.6 Hi David, > How did you cut the curve perpendicular to the surface in the rendered example? I actually swept an arc profile which is the same radius as the sphere (in blue) to get the result in the rendered picture. Is this what you mean? Cheers ~Danny~ Attachments:
