Blocks set automatically to points (Stadium seats) Solved


Hello I need your help.
Is there a possibility to set a block reference to selected points automatically.

I’ve divided my lines into points with Grasshopper.
Now I have about 15000 points and would not like to copy the blocks manually to every single point. The points may change again.

Can you do it automatically, with Rhino or Grasshopper … or is there an alternative

Hope someone can help,



no idea if this works but it looks maybe like what you need.
its from @dale

it seems you dont need grasshopper for this part.


As far as I know, you cannot use blocks in Grasshopper.

Pretty much similar to the script linked above, I generally use for this purpose this Python snippet:

import rhinoscriptsyntax as rs

pts = rs.GetObjects("Select points ...", filter=1)
blockName = rs.GetString("Name of block to copy ...")

if pts:
    for pt in pts:
        if rs.IsBlock(blockName):
            rs.InsertBlock(blockName, pt, [1,1,1], 0)
            print "No valid block name entered."
    print "No points selected."

(“Tools > Python script > Edit” to run a script)
