Oloid script

 From: bemfarmer 5 Oct 2013  (1 of 14)
 While researching Cones and developable surface, came across an Oloid. The Oloid shape is used in mixers, and as a toy which I never got to play with. Have to get a 3d printer some day. There are additional remarks in the script .js, regarding loft, mirror, and boolean union. http://www.heldermann-verlag.de/jgg/jgg01_05/jgg0113.pdf May try a torse "unwrap". Here is a script to create an Oloid, based upon portions adapted from Lineweb script, and ToroidHelix script. Using a higher line number will improve the Oloid "accuracy." 500 lines almost looks like a surface. Loft makes them a surface. - Brian Attachments:

 Not very exciting, but here is a script to make the 2d path, (unroll), of the oloid. - Brian Attachments:

 6211.5 In reply to 6211.4 This last one can be made by a simple 2 arcs circle + Transform / Array/ Dir ;) --- Pilou Is beautiful that please without concept! My Gallery

 6211.6 In reply to 6211.5 Hi Pilou. I cannot get a 3 point circle to match the curves, although it is pretty close, which suggests that the track is not quite of circular arcs? :-) - Brian

 6211.7 In reply to 6211.6 Yes you right max gap following middle along the circumference between a circle of 1 m radius and the oloidtorse is something like 0,0129 m so like 1/100 so sure not exactly the same! But for illustration that can be used ;) EDITED: 8 Oct 2013 by PILOU

 6211.8 In reply to 6211.7 :-) I copy pasted an oloid to Geomagic Design, stitched it, and exported to .bip, for keyshot3 (/4). I would try to do a "gomboc," but there apparently isn't any parametric equation. One link said it was "Constructive Solid Geometry." Did locate an .stl reduced version. There is a US design patent granted April 20, 2010, which lasts for 14 years. - Brian EDITED: 8 Oct 2013 by BEMFARMER

 6211.10 In reply to 6211.8 Hi Brian, here's an interesting 4 side screenshot from Rhino, of a gomboc. (please scroll down to the end of the page) Maybe it's useful for reconstructing the shape in MoI... http://totallyepic.net/mossy.html Regards Stefan my 3D doodles

 Thankyou Pilou and Stephan. There is supposed to be an infinite number of such shapes, but they are all also supposed to be within a few percent of spherical.
