3D drawings I am in charge of a task that make sure our company can get a totaly set of 3D models of a project design which always express in 2D drawings. There are a lot of difficults to reach that target. The first one is that designers are too habited using 2D design tools to use 3D drawing software. Further more, 3D softwares are not so ripen for drawing right now that designers always make complaint about that. In addition, standards of 3D drawings are such lack in the industry that it's difficult to judg the quality of the work. No matter there are so many difficult, I will devote myself to get the task done because I had been sufering problems of 2D drawings in all my projects for a long time before I learned the pros of 3D drawings, such as plenty of contraries between different 2D drawings which could take your about 90 percent of your work time to sort out and solve.
