I think you are showing exactly what I need. The others seem to think I want to create a shape inside of my current shape when I was just trying to add that large radius to my edges. Can you tell me more about how to anchor to the edges of the model? This is where I am lacking experience with FreeCAD, unable to define the sketch properly, or only to the main left edge and center point, rather than define based on the actual model. I am in part design mode currently, which might be another issue.?
I really appreciate you taking the time to assist, thank you!
