Re - do you guys work in draft mode, with renderable & non-renderable edges turned on?
Personally I work in wireframe as its much faster then staying in draft, and I find working in draft with renderable & non-renderable edges turned on a bit distracting.Re - And does RedSDK give you the option to use black edges, without applying a material, or do you just go with the default matching colored edges?
Yes - well - sort of, like many things in RedSDK there are both good and bad points, some people without the lightworks plug-in use Native draw = GDI mode, which although I'd like to use it, it limits what can be done in draft render like coloured edges, and doesn't support materials, it uses openGL as its engine.
In Native draw = RedSDK mode, one can have a coloured object (pen colour), a different colour for the outline, and another different colour for the 'hidden line' parts, all in draft mode, however although that sounds good - now for the bad side, with RedSDK one has to have 'draw form building edges' turned on (no choice), which looks terrible, so one uses degenerative faceting to make it look better (even though Degen is a terrible mode compared to GDI - except when dealing with snapping to the centre of a circular face), the problem with all this is Tangent lines (no idea what they are actually called so I call them tangent), and I don't know any way to get rid of them but they spoil the look. The line colours and hidden colours are global so every object irrespective of pen (object) colour will inherit the same colours (there is a minor variation but I won't confuse things with that now).
NOTE - things change again if one uses a material (but you asked about draft
