Sketchup 7 setting opacity with ruby?

[HPW]

Hello,

The API doc says:

Color.alpha= is only for SketchUp 8.0 M1+

Any other way to set opacity in Sketchup 7 with ruby?

This does also not work:

color_from_rgba = Sketchup;;Color.new(material.color.red, material.color.green, material.color.blue, 128) 
material.color = color_from_rgba

Oops, just noticed:

	 material.alpha = 0.5

For materials it's Material.alpha. If you are drawing polygons to the viewport using View.draw then you need Color.alpha.
