Hello! I am trying to create a sort of wedge in a bnc style connector. This will be a component that connects to another component. I want to make this path (shown in blue in the image) so that as the attachment slides in, it tightens due to the friction of the shrinking walls. If anyone has advice it would be much appreciated. ALSO somewhat unrelated but I am very new to solidworks and am looking for some free sources to improve my skills and exposure to the software. Does anyone have any recommendations?
