Remove layer doesn't work?!

sdafasdf

hi

sorry if this is a simple query, but it has me stuck.

I've added a layer to my model with

Sketchup.active_model.layers.add("test")

which works fine. The API reference says this should remove it,

Sketchup.active_model.layers.remove("test", true)

but it errors

Error; #<NoMethodError; undefined method `remove' for #<Sketchup;;Layers;0xc8649c4>>
(eval);81

anyone got any bright ideas?!

thanks
bob

Layers.remove is new in SketchUp 2015.
The API docs show the version of SketchUp methods were introduced.

Prior to version 15, you need to do it using Layers.purge_unused after moving or deleting any geometry on that Layer.

TIG posted some code here: http://sketchucation.com/forums/viewtopic.php?p=166985#p166985

thanks Jim, I hadn't spotted the 2015+ in the docs

I have (hopefully) one more layer question. Is it possible to set the layer opacity and then turn on "color by layer"?

thanks again

Jim

For Color by Layer, see the Rendering Options[1]


Sketchup.active_model.rendering_options['DisplayColorByLayer'] = true

I do not think the transparency can be set from Ruby.

Jim is correct.
If, via Ruby, you give a layer a color with transparency it is ignored and it renders opaque.
Sp currently you can only change a layer's color through the API - there is no alpha OR texture support within the API, although of course you can do both of those manually...
