Hi All.

I am new to SolidWorks, and to CAD in general. By day I work in the electronics industry, by night I'm your typical try anything hobbist.

My employer has recently given me the opportunity to expand my capabilities into new areas by providing me with a SolidWorks license, which I've been using to (attempt) to draw up random fixtures and gadgets that would make some of our operations better. I have learned a lot from reading through this forum and watching youtube videos and I have been amazed by house easy much of this has been to learn. That said, I have run into my first true roadblock that I have not yet been able to solve.

What I am attempting to do is to model a traffic cone that has an access hatch in the side. I have been successful in modeling the cone with the hatch cut into the surface perpendicular to the axis of revoloution of the model, but I have not yet been able to figure out how to draw the hatch so it is perpendicular to the to axis of the surface, not the axis of body rotation.

What I've done is draw the 2 outlines for the hatch on separate sketches, and then I am attempting to make the shape by using the 'Offset from surface' and 'start from surface' options in the extrude cut menu, but the only success I have had is by getting it to cut perpendicular to the model axis.

What I was thiunking would be a good way to do it was to project the two sketches (I'm using two sketches so I can generate both the hatch and the lip that the hatch sits on) onto the surface of the cone, and then cut from there, but it won't allow me to use the projected curve as the cutting sketch for the extrude cut. 

I've attached an image of what I have now, if there is anything I need to explain better please let me know. I'm still very new to this so I'm very interested in what ever ideas you might have.
