If you just study CAD, it can be said that it has no future, because it is the most basic tool for all those who study architecture-related majors, and it is as simple as an ordinary calculator for related majors, but if you can play CAD to the extreme, it may still be very promising. If you can only use CAD, you can be a cartographer, but the salary is very low. According to the size of the city and the company, the salary is basically around 1500-4000.
