Since I don't have much time invested I might consider going a different route if there is something with a quicker learning curve for 2D. I will be using it as a layout tool to determine angles and dimensions for simple jigs and fixtures. Any suggestions? Doesn't have to be free, I have no problem paying for the best tool for the job.
I find angles and getting the relationship right between faces and features difficult in sketchup.
There are several other GJ threads about cad and 3d software.
Draftsight is a full feature, Autocad level program from Dessault systems. It is entirely free for personal use. I think it is just as hard to use as Autocad too
LibreCAD (free) and DeltaCAD always get votes too. DeltaCAD has been around forever and is fairly straightforward.
If you are working with solids, autodesk has some free choices too. Check out

I don't think there is any reason to pay for design software unless you are using it professionally, and even then... if it doesn't violate the license, why pay more?
For years I paid to keep TurboCad current, but not anymore...
Honestly, the fewer features, the quicker you will be working in it. When you find things your free software just won't do, then upgrade to paid.
Depending on how involved the drawings are, Visio from Microsoft might be a good choice too. I use it all the time for floorplans and layouts. It's really easy. (But paid. I think you can get a trial online from MS.)
There are tons of online diagramming tools too. Just google 'visio online' and you'll get a ton of hits.
If that didn't help, ask again and I'll try some more
