Hi, V5 if a number of points are expected to fit a circle (or vice versa !) there is the circle through points option. Obviously if the points are random we dont even contemplate it. Likewise its possible for an elipse to fit points. I see no option for this though and need to plot an elipse th…

I’m trying to use this to rebuild an ellipse from a mesh make2d. any suggestions? [image]

Hi, [image] attached an example of need for ElipseThroughPoints command as easily selected as circleThroughPoints. I have to establish the size of an eliptical tank and can only see indication of its welding onto a bulkhead. Anyone care to solve the fit of the eliptical tank weld I can see trace…

Do you know enough about the dimensions of the real object that you could model it in an orthographic view based on circles then rotate it in space to derive your ellipse using Make2D? Dennis

I know its width but not height, how would I do that, create a circle at 90 deg to the elipses plane then rotate circle3d whilst looking at it in a different ortho until a visual match, how do I get it to fit points, visual ? When CAF is a mathematical geometry sort of thing, visual seems a little…

Hello! I know this is an old thread, but if anyone else in the future is looking through this thread for an answer, I would suggest this tool. [image] Ellipse given 5 points v.1 A Rhinoceros plug-in for drawing an ellipse given 5 points I use it for tracing …

Hi, thanks for this. I see rhp and also rhi files, not sure which I need. (need to remind myself how to apply this file after downloaded) V5 I also could do with best fit elipse through a number of points., where clearly the points form an elipse, as in my initial image. Steve

This must be a record for ‘blast from the past’ post!

if you have points and you want to fit an ellipse to it. there is no option in grasshopper/rhino to do it directly so i wrote a python script in grasshopper to do it. I have attached the files also here is the github too: Grasshopper_ellipse_fit_code.py (14.3 KB) example_gh_elliplse_fit.gh (11.8 K…

Hi, yet again I need to fit elipse best fit to points I want an elipse for and I know its sort of elipsey in shape. I dont have grasshopper. Thanks for the Grasshopper offer though. Surely there is a way of best fit elipse through elipse shaped points distribution. Now trialling V8 should anyone…

Rhino V8 comes with Grasshopper.

[image] AlW: Rhino V8 comes with Grasshopper. As did 7, 6 and 5. In V4 you had to download it separately.
