CAD Operator Aichi and WinSchool

Hi there. Foreigner living in Aichi close to Toyota city. My child is gonna born soon and when my wife returns to her workplace she is gonna have only weekends off. I work on the service industry and I have to work on the weekends, I want to avoid give my wife more work that she already have with the child so I am looking to change work for a place that at least gives me sunday or saturday off.
I dont have a background on IT or Engineering but I am thinking as option to study for a while on WInSchool and get to use CAD software. Since Aichi is a industrial prefecture maybe is a good option on the long term. I've research about it but I've got mixing information. If there is CAD operators here or people who really understand Id like to ask some constructive opinions about it.

Thanks for reading.
