a question

I want to have a number of points on a surface which their distances are not more than a specified lenght. Could you help me?

Thanks

Have a look at this thread...

I am reading the materials which are on this thread. Thank you. As I've found out up to now, it is about disturbuting objects evenly through a surface. It somehow differs from what I want, for I'm thinking about disturbuting randomly a specified number of objects through a surface which their distances would be in a adjustable range.

Hi Maryam,

I take it you are referring to a freeform surface, in that case one option would extract isocurves form the surface and then divide the isocurves with points by distance.

these won't give a regular grid and you may need to insert extra points because it is not possible to know the distance between points on a freeform surface based on surface parameters as the mean curvature impacts on this.

I remember seeing a video from Daniel Piker using kangaro to create a force driven distribution on a freeform surface, this would be a much better solution.

Hi Maryam,

It was done on GH 7.059, (also works on 8.001)
Forget the rhino file, just attach your surface to the Srf component on the definition.

I hope this helps!
