Understanding Architectural Drawings（理解建筑图纸）.pdf

CHAPTER 1 Understanding Architectural Drawings THE FOUNDATION OF ANY 3D visualization is the linework found in its architectural drawings. Just like a contractor needs drawings to erect a building, a 3D artist needs drawings to create a visualization. Understanding a set of architectural drawings is critical to efficient and accurate work in 3ds Max, and without knowing exactly how drawings are put together and what each component of a draw- ing indicates, a 3D artist is likely to spend a great deal of time trying to make sense of the madness that can be a set of architectural drawings. Today, nearly all building projects utilize CAD to create architectural drawings, and more specifically, AutoCAD. However, many visualization projects begin long before the final construction drawings are generated. Construction drawings are the final set of drawings submitted to a city or county building department and supplied to contractors that intend to bid on the project. These ’final’ drawings often lead to addendums and on-site adjustments, but construction drawings will always have a certain acceptable level of quality and engineering. The same cannot be said for the drawings that those of us in the 3D world are often forced to work with. Since our work often begins at the design development stage or before final construction drawings are generated, we often face the challenge of working with incomplete drawings containing numerous errors or conflicting data. Whatever the case maybe, architectural drawings can be a difficult thing for many 3ds Max users to grasp, especially for those that haven’t had the benefit of working as an architect, engi- neer, or draftsman. I decided to make the first few chapters in this book a discussion on architectural drawings and AutoCAD because many intermediate level users in 3ds Max do not have a solid background in architectu
