Hello everyone
I don't find a command to make rhino calculate the average point of a cloud of points... Could not be there?
Thank you.

in the do a group and look for the center (baricentro)?
But I don't understand the concept of "points flying", because I don't use it...

cloud of points is a group of points... .
the problem is that the centroid only makes it of areas or solids.
I think I solve this: I design so many equal spheres around each point and then calculate the center of the spheres. But it seems absurd that there is no special command.
Thank you.

a curiosity: what is it to calculate the average point of the cloud of points?

Sorry, but how does rhino or any other software calculate the center of a volume if the cloud of points a volume does not have?

then just read what the command prompt indicates after you call the command: select the solid or closed mesh 3d for calculation of volume :smile:

the center (centroid I find it a useless Englishman!) of a cloud of points is the result of a sum and a division. can also calculate excel, why should a software not be able to do it?

Hi.

then just create more simplyr a boundig box (parallelepipedo limit) that inscribes the point cloud and consequently to this extract the centerpiece of the volume.

I have reported that the special command**** to calculate the volume centerpiece does not handle the clouds of points taken as they are

** means "turn a button and do all of it"

However, it seems to me that in the newsgroup of rhino ita there is a vbscript attached to do this; you have to read the threads or do a search
maybe it was put/linked even in rhinoceros wikipages

however I wanted to make a reflection;

the calculation of the centerpiece is subordinate to the correct layout of the object; if the cloud of points is not referred to a coordinate system, for example the global axes of rhino, the boundingbox is calculated differently, as from image

Hi.
I need it as I did a series of reliefs through an acquisition system applied to a profile viewer and I rebuilt on rhino the profiles of thirty samples taken from a production lot. as I am interested in the statistical side of a share of these profiles, I was comfortable: to draw a line that corresponds to the desired quota, to identify the points of intersection of the profiles with it and to calculate the average point (or center or center of the group of points)

I read!
but I am interested in identifying the center of a group of points, not a solid or a surface. . .

I don't think that's how you calculate something else.
