Hi. I’ve been doing mechanical designs for over 40 years. I was using CDADKEY but it is not supported anymore and doesn’t load on Windows 10. I am now a senior but delve in mechanical design from time to time, i.e. sheet metal and machine parts but I like to sketch out ideas of various things from time to time. I’m too old to try and learn or even use a 3D software package, but possibly someone out there can recommend an affordable 2D package. I’d love to hear from someone who knows rather than signing up for free trials without knowing that it is what I want. Ric in Ottawa.
