How do novice CAD drafters draw the cross-section of a cabinet?

Example: You need to draw a cross-section of a square box, but whether the box is made of stainless steel or wood, how thick are the side panels of the box, are there pillars around it, how many layers and partitions are there inside the box? What material is it made of, ------ and many more. If you don't know these, you can't draw the cross-section of this box.

So, if you want to draw the cross-sectional view of the hotel front desk cabinet, you should do two things: 1. Completely understand the external and internal structure of the wine cabinet, as well as the production process, otherwise the drawn structure cannot be made. Or the cost is too high, then this picture is a failure; 2. The cross-section markings of various materials must comply with the relevant provisions of the national standard.

To put it this way: this picture is not the responsibility of the draftsman, but belongs to the design. By the way: In the past, after manual drawing, the draftsman needed to trace the hand-drawn drawing into a base map in order to print the blueprint. Nowadays, computers are used for drawing, which can be printed directly, so there is no such thing as a draftsman.
