Hi Mik,

re:
> Yes, and Style named "Hidden lines" is associated with white color after run the script.

If there is an already existing style named "Hidden lines", it will use the existing one and won't change the color to white.

So if you wish to avoid getting the white color, set up a style named "HIdden lines" before you run Make2D.


> Is it possible to change this white color to be same as visible lines?

You can change it from white color to some other color but visible lines will inherit the style from the generating object and there is not a way to make hidden lines do that as well because that would pile up both visible lines and hidden lines in the same place.

Hidden lines generated by Make2D just exist in the model same as any other curves, they do not have any special attribute.

Hidden lines generated by 2D drawing construction during PDF/AI/SVG output will make use of the settings in the Line Style Options dialog.

Still not sure if I understand your question though.
