I am having trouble making these half circles meet the end of the square they are on flush. They essentially need to end at an angle that is the same as the edge that they meet. Anyone know how I can do this? Thanks
If they are solid objects you can model a cutter at the edge of the background and use it to trim the ribs with the Solid Tools. Make sure the ribs extend well off the background first.

This looks like exactly what I need to do but Im a little confused by the directions. Do I build out that ‘border’ I see in the beginning of your video? Does it matter if things are grouped? I have never used this tool before
I drew that frame sort of thing as a solid object and I made the ribs as another solid object (group or component). That’s required in order to use the Solid Tools. Then I used Subtract to subtract the frame from the ribs.

Do you mind taking a look at my model? I cant get it to work!
Your model is kind of a mess. I’ll send you a PM shortly.
