The copper is extruded along the same path so it's no extra effort to do, two clicks actually. All components must be visible, copper thread included, it's gonna be a layered pic in flash where you can turn off insulation layers and see what's inside.
I had to rebuild the thing, an engineer buddy said the coil density was way too high. So it looks more realistic now. Lighting is default, looks cheap i know but i had enough.
