在商业上，许多用户会寻找 AutoCAD DWG 和 Bentley DGN 格式.虽然不是免费的，但可以从 开放设计联盟

Commercially, many users will look for AutoCAD DWG and Bentley DGN formats. While not free, libraries for producing these formats can be found from the open design alliance

GIS 社区将形状文件用于矢量化 3d 模型，这是一个免费的 SDK可以在此处找到形状文件.OSG 库也是免费的，支持多种矢量图形格式.

The GIS community use shape files quite a bit for vectorised 3d models, a free SDK for shape files can be found here. The OSG library is also free and supports a number of vector graphics formats.
