I'm currently trying to use SolidWorks to work on the geometry of two vertebrae and the disk between them. I got a model from grabcad (at the following link: GrabCAD - CAD library). However, I need to get rid of the bridge between the two edges of the vertebrae. But I'm not sure if I can edit this model or how to do so. I haven't used SolidWorks in almost a decade, so I have a hard time distinguishing a part that can't be worked with and a part I don't know how to work with. If it's possible, I'd like to make a cut straight down from the line in the image below (or one similar to it) all the way through the vertebra. Is this possible, and if so, what's the best way to do it?
