Nested linked block selection

Scripting
,
1

Hi,

I am having trouble with sub nested block selection : when using sub object selection I can select any child block, but when running a script asking to pick select blocks, only the parent block can be selected.

Is there a way to keep sub object selection effective while running a script ?

rs.GetObject() allows the subobjects=True parameter, but it looks like rs.GetObjects() (plural) does not have that parameter. If you need to select multiple sub-objects, you may need to use the Rhino.Input.Custom api (https://developer.rhino3d.com/api/rhinocommon/rhino.input.custom).

import Rhino

def select_multiple_subobjects():
	go = Rhino.Input.Custom.GetObject()
	go.SubObjectSelect = True
	go.SetCommandPrompt("Select subobjects")
	get_result = go.GetMultiple(minimumNumber=0, maximumNumber=0)
	if get_result == Rhino.Input.GetResult.Object:
		selected_objects = go.Objects()
		return selected_objects
	if go.CommandResult() != Rhino.Commands.Result.Success:
		print(go.CommandResult())
	return

Thanks for your quick response.

Your example led me to the solution, I tried SubObjectSelect but it didn’t work because of the following line :

go.GeometryFilter = Rhino.DocObjects.ObjectType.InstanceReference

Once removed it work as espected. I link the code with the commented line as example.
