Need a script pleeeease? > join by layer

Rhino Rhino for Windows

Hi All,

I imported an assembly where each layer is a part, but they came as individual surfaces, not polysurfacse/solids. I’d love to have a quick way to run a script that looks at my file and joins all the surfaces on the same layer/sublayer? right now it looks like this (with lots of scrolling):

I’d appreciate the help!

Hi G,

Are you familiar with running python scripts?
Below the script that will automate what you want.
It is bare and maybe slow but that’s all I have time for right now.

I advice you to test it on a subset of your file first

import rhinoscriptsyntax as rs

def JoinByLayer() :
    layer_list = rs.LayerIds()
    
    for layer_id in layer_list:
        rs.UnselectAllObjects()
        
        rs.SelectObjects(rs.ObjectsByLayer(layer_id))
        rs.Command('_Join')
        
if( __name__ == '__main__' ):
        
    JoinByLayer()

I tried all i know about programming:

and that doesn’t do it. please don’t judge :smile:

No worries,

EDIT I just now realized you had it almost correct in the macro editor:
in your macro it should be:

!_-RunPythonScript (

import rhinoscriptsyntax as rs

def JoinByLayer() :
    layer_list = rs.LayerIds()
    
    for layer_id in layer_list:
        rs.UnselectAllObjects()
        
        rs.SelectObjects(rs.ObjectsByLayer(layer_id))
        rs.Command('_Join')
        
JoinByLayer()

)

In the Python editor it goes like this:
Open Pyhton editor Command: _EditPythonScript

Next open new tab:

Paste the code and hit run button

HTH
else let me/us know

Going to suggest a small improvement to Willem’s script… Cut the redraw to go a bit faster and a check to not run join if there are no objects selected (layer empty, all objects locked, etc…) or just one…

import rhinoscriptsyntax as rs

def JoinByLayer() :
    layer_list = rs.LayerIds()
    rs.EnableRedraw(False)
    for layer_id in layer_list:
        rs.UnselectAllObjects()
        rs.ObjectsByLayer(layer_id,True)
        objs=rs.SelectedObjects()
        if objs and len(objs)>1: rs.Command('_Join')
        
if( __name__ == '__main__' ):
    JoinByLayer()

Hi all, no luck so far:

Willem, Your script asks me “Select Object to Join” in command line after running it.

Mitch, yours doesn’t do anything

:sob:

Hi G
On my phone so not much testing possible.
Did mitch.s script get copy pasted correct?

It might be some lines got wrapped.

Probably because it ran into a layer with only one object or none…

You need to add the

! _-RunPythonScript (

at the top

and

)

at the bottom (as in Willem’s example), I don’t normally post scripts with that added.

Yeah there are layers with just one object or none (parent layers of other sublayers).

this is what I’m running:

Oh yeah, I forgot, just remove the “if name == main” line, and out-dent the line below it. Doesn’t work in a toolbar button with “if name == main”. Sorry for the disinformation…

Like so:

! _-RunPythonScript (
import rhinoscriptsyntax as rs

def JoinByLayer() :
    layer_list = rs.LayerIds()
    rs.EnableRedraw(False)
    for layer_id in layer_list:
        rs.UnselectAllObjects()
        rs.ObjectsByLayer(layer_id,True)
        objs=rs.SelectedObjects()
        if objs and len(objs)>1: rs.Command('_Join')
        
JoinByLayer()
)
