CAD View
Shows what the original
CAD work looks like using the CAD colors.
It can be very useful to come back to the CAD view from a rendered view when you are working up a rendering.
For example you may have some objects underneath an area fill that cannot be seen in the rendered view, but are clearly visible in the CAD view.
You can select the object to find out what layer it is on using the info tool and then move its position in the Layers list.
