I am a CAD chemical designer. I usually draw process equipment and construction drawings. Now I can draw it simply, but I always feel that I haven't felt the pulse yet.

The quickest way to learn is to go to a professional place to study. CAD indoor architectural drawing is the basis of three-dimensional interior design. Generally, CAD indoor drawings will be built, and then the drawings will be imported into 3D to make a complete set of efficiency drawings. You can also consider the parameters according to the CAD size, and then build one room at a time in 3D. But this knowledge requires a lot and proficiency. It's not enough if you don't spend time. Learning 3D suggests that you go to a regular local school, which is not only fast, but also makes you concentrate more.
