In order of decreasing emphasis บริษัท ปรีชาคอนกรีตไพล์ จำกัด on science, the key functions of all engineering branches are the next:

The whole process of generating engineering drawings is usually known as technological drawing or drafting (draughting).[1] Drawings generally comprise multiple sights of a element, While extra scratch views could possibly be included of aspects for further explanation. Only the information That could be a necessity is usually specified. Crucial data which include dimensions is generally only laid out in one particular area with a drawing, averting redundancy and the potential for inconsistency.
The 2nd basic principle—that Although scaling the drawing will often operate, a single must Nonetheless never ever do it—serves a number of aims, which include imposing complete clarity relating to who has authority to discern style intent, and preventing faulty scaling of the drawing that was by no means drawn to scale to start with (which is usually labeled "drawing not to scale" or "scale: NTS"). When a consumer is forbidden from scaling the drawing, they must convert rather into the engineer (for that answers which the scaling would look for), and they're going to in no way erroneously scale a thing that is inherently unable to be precisely scaled.
