In my experience scripting in Vectorworks, there was a way of ‘moving’ an object from inside a container to another one, a function called SetParent. I would like a method to move a Group inside a ComponentInstance, like a user would at the Outliner window!

I need to point out an error in your thinking. Component Instances do not “have” entities. It is Component Definitions that “have” (or “own”) an entities collection. All instances of a certain definition will share the parent’s entities collection. So you’d actually move a group instance, into a …

Thanks Dan! I understand your point, the container is the ComponentDefinition not the Instance (a mere reference placed in the drawing). I’m doing exactly the .add_instance thing, using group.entities.parent for versions before 2015. Is this the only way? For instance (no pun intended), adding a …

To ‘Move’ a group into another context and keep all of its original ‘properties’ - so it appears you have haven’t actually ‘Copied’ it - you make references to them apply them to the new ‘instance’, then erase the original group… grp ### the reference to the original group newgrp = cdef.entities.ad…

Wow! Thank you so much for the code!

[image] TIG: newgrp = cdef.entities.add_instance( grp.entities.parent, grp.transformation ) Am I wrong or does this Bugsplat if cdef is not Sketchup.active_model?

[image] hank: newgrp = cdef.entities.add_instance( grp.entities.parent, grp.transformation ) I suppose that depending on what cdef actually refers to it might BugSplat, and that would be a bug because SketchUp should trap and reject illegal operations. But I tried setting cdef to be the Comp…

I’ve never had such a bugsplat and I quite often add instances to groups and components.

Are we talking about add_instance or add_group now? I’ve gotten the latter to crash by passing entities not in the active drawing context, but never the former.

Correct. You can add_ geometry etc, or instances of component definitions or groups into any entities context - i.e. to the model.entities, model.active_entities, and group.entities and definition.entities A new group can be added to any entities context using gp = some_entities.add_group() If en…

Is there some kind of "set parent" method to "move" a Group inside a container?

Really? But what about…

@ TIG Move all entities to new group

Maybe I misunderstand what is being warned against.
