Years ago I was pretty comfortable with a 2D CAD program called DesignCad.

Would like to find something for home/hobby use today.

Do not want to make the necessary time investment to learn something that is free today, but could either disappear tomorrow, or become expensive.

Curious what members here are using...

No experience with 3D CAD. Probably only need 2D. Perhaps 2D is archaic now?

Willing to learn...

Recommendations/insight highly appreciated!

(I did try the search function but came up empty handed. Perhaps I need help there too?)
