How to cut extrude a 3d sketch in solidworks

Working on a pair of sunglasses fit for 3d printing, firtst time for me.
For CNC, I dont need to draw the groove for the lenses, but for 3d printing I do.

I have drawn a 3d sketch on the edge of where the lens has to be. I want it to cut extrude 1mm to the side and 1mm into the frame, creating a 1x1mm groove for the lens. i am able to get a preview when i use a cut sweep, but i get the Zero Thickness error :(

Anyone an idea for a solution?

A part of the contour of your sketch must be outside of the part.

Here is my approach. I think the frame should be modeled around the head(eyes) and the lens. You can't "bend" the lens, therefore the frame must follow the lens too.

Hi Maarteen,
Another approach could be used to remove material and make the groove : If lens is defined in place, copy its surfaces and choose remove from surface, this should work. Not enough time to test by myself, sorry.
