I have two low cost options for you.

The first is to join the Experimemtal Aircraft Association EAA for $40 per year. This gives you access to one year of Solidworks Education Premium. This is a full featured version of Solidworks which also has 2.5 D integrated CAM.

The second option is to sign up for a one year educational access to Autodesk software, which incidentally includes access to Fusion360. I am a retired engineer taking just a single class at the local community college, and I was able to sign up for the Autodesk educational access. Alternatively you could get access if your children are in high school or college.
