You deleted her but never 'purged' the scene, Purging will remove materials.

Open your component Browser and look at the "in model" tab. It will show that there is still at least 1 component in the model. It is not being drawn anywhere in the model, but it still has a component definition saved in the model, so the model still considers the colors as being used.

Note: model.materials.length also include materials which Image element uses.

Say you have 2 materials listed in SU's material browser:
Material1
Material2
And you also have one Image element in the model.

Then model.materials.length will report 3.

Even more:
Sketchup.active_model.materials.each { |m| puts m.display_name } Material1 Material2

Notice it only lists the two material visible in the material editor.

This on the other hand:
(0...Sketchup.active_model.materials.length).each { |i| puts Sketchup.active_model.materials[i].display_name } Material1 Material2 Image1

Now you get full access to all the material - even the ones that belong to Image elements.
Be careful! I've had models where image materials has been applied to other geometry - which has lead to problems as you can't select or interact with the material in the Material Browser. So in most cases you want to iterate using .each.

To get a count of just the materials available in the material browser:
m_count = 0 Sketchup.active_model.materials.each { m_count += 1 }

Cool... except that I purged and there is still one material left - "0135_DarkGray". What's up now?

You have it selected. The currently active material will not be purged. Select the default material before you purge.

I see... is there a way to find/change the currently active material thru Ruby?

Sketchup.active_model.materials.current = nil

Chris Fullmer

material.current is not in the API docs. Do we have that in the thread of things for Scott to fix?

thomthom

Sorry, it's model.materials.current

Chris Fullmer

Sorry, I could have checked that....

Is that being checked by Scott still?
I'm a bit confused if we're supposed to comment in the API docs...

There is a reported difference between materials.current on PC and MAC.
On a PC it's the currently selected material
On a MAC it's the last used material and this ignores what might now be selected IF it's never been used...
