How to get edge/line color?

[bigstink]

Hi all,

Using Ruby, is it possible to retrieve the color of an Edge object?

I am working on a plugin and I have no idea how to access this information from the code.

Any help is appreciated

1. View the API for Edge, but there isn't anything about colors there.

2. Realize an Edge is a Drawingelement, and so inherits the methods of Drawing element.

3. Find that Drawingelements have a material property, which returns a Material.

4. See that a Material has a color property.

In Short, with a single edge selected..

some_edge = Sketchup.active_model.selection[0] edge_color = some_edge.material.color

But, if the edge has no material, this will give an error because some_edge.material will return nil. So you should check the Edge has a material before asking for the color.

Hi Jim,

Thanks for pointing me that way but it appears that the material for my lines is null/nil.

I see if I go to Windows->Styles, then click on Edit in the newly opened window, I can change line colours from there.

Is this information exposed through a different API maybe?

Yes, Style settings are accessed in the Hash-like RenderingOptions. You can view all the RendingOptions using this line in the Ruby window.

Sketchup.active_model.rendering_options.each {|k, v| puts "#{k} = #{v}"}

There does not appear to be a key for an "EdgeColor"

Ah, it is the ForegroundColor key.

Perfect, those rendering options will come in handy!

This works great, thanks Jim
