Thanks. I can't see any differences between when "back edges" is turned on or off. CB.

You are correct. I filed a beta bug report, and Simone logged it as internal bug 2916316.

Additional comments, and ideas I posted:

OK.. I looked at this a bit further, and my conculsion is that...

RenderingOptions[’EdgeDisplayMode’] needs to be updated.

The setting is tied to Edges

Currently the value of the RenderingOptions[’EdgeDisplayMode’] key is 0 when both are turned off.
Toggling Edges ON adds 1 to the value. (BUT.. if BackEdges is ON, and you turn Edges OFF, the value remains at 1.)

We need toggling BackEdges ON to add 2 to the value, so that:

RenderingOptions[’EdgeDisplayMode’] :
0 = both OFF
1 = Edges ON && BackEdges OFF
2 = Edges OFF && BackEdges ON
This may not be used (rendered,) meaning that mode 3 would be enforced, but we should still be able to test for mode setting 2 (the state of checkboxes in the Styles dialog, and the menu item check states.)
3 = both ON

thanks, but
in ruby console

Sketchup.active_model.rendering_options["EdgeDisplayMode"] =

works only 1 and 2

Sketchup pro 8.0.3117

It should only have 0 and 1 values at this time.

You did not read what I said correctly. I am proposing that values 2 and 3 be added to the API so that we can know the BackEdges setting.

Sorry, i mind 0 and 1..
And how can I add it to API?

ps. my English is not good

You CANNOT.

Google must do it on the C++ side of the application code.

That is why I filed the Bug Report, and a number was assigned to it, by the Sketchup Development Team.

Any updated info for this topic?

YES. (5 years after this thread ...)

In the SketchUp 2015 release, a new key was added to the RenderingOptions hash:

The key is: "DrawBackEdges"
