Which is more difficult to learn, CAD or photoshop, and where is it used?

The two softwares are used in different fields, but personally, CAD is more difficult to learn. PS is more difficult to use

CAD is abstract and involves some professional knowledge, such as projection, three views, 3D space and so on.

PS is more intuitive. PS is an extremely personalized software, which can create completely different works for different people.

So CAD depends on your technical literacy,

And PS depends on your artistic accomplishment!

CAD is mainly used in engineering design, such as machinery, architecture, clothing and so on.

And PS is mainly graphic design, such as posters, magazines, web pages, printing and so on.

Influence, this has not been investigated. Ha ha.

User base, it is estimated that PS is bigger! Read the computer newspaper, then you know PS ~

I hope my answer is helpful to you ~!
