Hi @JeoCho,

The attribute is "/ce/block/type"

And the possible values are:
"Skeleton Subdivision", "Recursive Subdivision", ... (Same as in the inspector)

If the attribute is not shown as bold in the inspector you need to not only set the value of the attribute you also need to set the source of the attribute to user.

Here is an example, I adapted it from the python docs to match your case

block = ce.getObjectsFrom(ce.selection)[0] ce.setAttribute(block,"/ce/block/type", "Offset Subdivision") ce.setAttributeSource(block,"/ce/block/type", "USER")

Hope this helps!

Best,
Jonas

Wow wow

Really thank you , really thank you

Sorry , can i question one more ?

models = ce.getObjectsFrom(ce.scene , ce.isgeneratedModel)

I generate model in a certain block

And i would like to select genrated model only

Like this

models = ce.getObjectsFrom(ce.scene , ce.isgeneratedModel)

Is that possible ?

Sorry many ask

Hi again,

Sure this is also possible. You just need to change your filter from ce.isgeneratedModel (this is no valid filter!) to ce.isModel. And then select it using ce.setSelection()

# all generated models in scene models = ce.getObjectsFrom(ce.scene, ce.isModel) ce.setSelection (models)

Shapes which have a rule file assigned but aren't generated won't be included in the ce.isModel filter.

cheers
Jonas

really really thank thank thank you for answering

i made this script

but error,

really really sorry , pls can you check this 2 script

1. this is script to select ( select generated model in selected block)

but error

from scripting import *
ce = CE()

def selectblock() :
oneblock = ce.getObjectsFrom(ce.selection, ce.isBlock)
lots = ce.getObjectsFrom(oneblock[0] , ce.ismodel)
ce.setSelection(lots)
if __name__ == '__main__':
selectblock()

2 this is layer isolate script

that is error also

from scripting import *

ce = CE()

@noUIupdate
def main():
sele = ce.getObjectsFrom(ce.selection, ce.isLayer)
layers = ce.getObjectsFrom(ce.scene, ce.isLayer)

for layer in layers:

really really sorry sorry for many ask

layer.setVisible(False)

if sele :
sele.setVisible(True)

if __name__ == '__main__':
main()

Hi again,

First script:

There is a typo. instead of ce.ismodel you have write ce.isModel.
If you want to get the shapes of the block instead write ce.isShape

Second script:

There is no layer.setVisible()
you need to use ce.setLayerPreferences() for what you want to do

Some general advice:

If you encounter errors check the message in the log, usually gives a good idea about what could be wrong
Use print statements to debug

Best,
Jonas
