Add entities to a layer

sachi

Dear all,

i want to control the visibility of several components in my model. to do that i add a new layer to the model. now i want to assign those components to newly added layer(new_layer). how could i assign those components to the new layer?
theoretically there should be something like
new_layer.add component_entity
help me.thanks in advance

The work flow is more like:

layer = Sketchup.active_model.layers.add "My New Layer" component_entity.layer=layer

Good luck!

As Chris says...
You add an entity into an entities 'collection'.
Like model.entities, group.entities, definition.entities etc.
An entity can then be assigned a layer: entity.layer=my_layer
It's advisable NOT to assign layers to 'raw geometry.'
This will lead to confusion...

Assigning a .layer= is the same as you do to assign a .material=, .hidden=[true/false] and so on.
Layers are used to control objects' visibility, not to separate geometry - that separation is done using a 'container' like a group or definition, the container can then have a layer assigned too...

thank you very much for the detailed explanation TIG. It cleared the doubted areas about the layers.
