I can’t find a way to make a simple thing with only few comand, that would take me hours if I have to do it one by one.
I have a point network created from projection on a surface (precisly a city model). I just want to place solid cubes by the midle of their up face on each point to create a cubic simplification of the city volume.
I hope I’m clear enough (and excuse my writing I’m french) but maybe this exemple can help :
This is an exemple of the aspect I want ti create.

Sub Main()
Dim arrsurf, origine, arrpt,strpt,endpt
arrsurf = rhino.GetObjects("selectionne les objets à copier!")
origine = rhino.Getpoint("Selectionne le points d'origine!")
arrpt = rhino.GetObjects("selectionne les points d'arrivés!", 1)
For Each strpt In arrpt
endpt = Rhino.PointCoordinates(strpt)
Rhino.copyobjects arrsurf, origine, endpt
Next
End Sub)
The above is not a python script, it’s a VB Rhinoscript. You can run it with Runscript, not RunPythonScript. Or, you can try this python script “CopyObjectToPoints”
“CopyIbjectToPoints” is a solution but only for one object at a time. I need to do the same for many objects at the same time, each of them having their own point to move to. Maybe the VB Rhinoscript can be a solution but unfortunatly I can’t run it, when I try there is a message “Command: -_NoEcho”
The question is how are you establishing the relationship between each ‘cube’ object and the point it has to move to? That is to say, how do you tell Rhino which cube goes to which point?
Your right excuse my imprecision. Each cube have to move vertically, to a point above him. Each cube have his own point above him. Maybe a picture can help. (when there is no point, the cube don’t have to move and I will not select it when I execute the command)
I think you have to learn python scrippting…
it’s a simple script to do, but it take time, and when you start to script, you can’t stop…
en français: lance toi dans le python, ça marche fort, et ça ouvre pas mal de possibilité!!!
Aha… that’s a totally different problem. There are several ways to approach this, for example project the points downward and see if they intersect with a cube and if so move the cube from the bottom most or top most intersection point back up to the original point. Grasshopper seems ideal for this, but a script can do the same. I don’t have time this afternoon unfortunately.
I know and it’s a thing I wanted to do, I began for other projects on other platform but like you said it take time. I’m wanted to see if someone had the same problem before but don’t worry , I’ll dive myself in it one day. Merci pour le conseil !

##point used once, remove from list - faster if many pts
pts.remove(pts[i])
#jump out as point has been found

Thank you so much both ! Each one of your code work, but I have to say that @Helvetosaur made one that is instantaneous and all my volumes in one command. You made my day !
