也许还有人不知道，AutoCAD Map 3D 2011已于近日发布。下面是这一版本的主要功能介绍：
Highlights & Enhancements
Point Clouds（点云） – Import and visualize large sets of point cloud data, such as 3D laser scanning/LiDAR data sets with billions of points, in AutoCAD Map 3D 2011 with the Point Clouds feature. With the Point Clouds feature, you can:
· Import LiDAR data in LAS and ASCII file formats 导入LiDAR数据
· Stylize point data based on LAS classifications, RGB, elevation, and intensity 对点云数据按照分类、高程、反射强度等进行样式化，即设置不同样式
· Filter point data by spatial extent and LAS classification, elevation, or intensity按照空间范围、分类、高程、反射强度等进行数据的过滤
· Snap to points within the point cloud using standard AutoCAD® software tools 可以对点云使用AutoCAD的捕捉工具
· Export surfaces as digital elevation models (DEMs) in GeoTIFF and ESRI® ASCII GRID file formats 以多种格式导出DEM模型
· Export point cloud layers to LAS, ASCII, and SDF file formats 导出点云数据为多种格式
3D Surfaces（三维曲面） – Generate 3D raster surfaces from point clouds and survey data – even via FDO connections. 从点云和测量数据生成三维曲面
§ Visualize terrains in 2D or 3D 地形的样式化
§ Drape raster data over surfaces 曲面上的光栅图像叠合
§ Fully integrated into the user interface 完全集成到用户界面
New FDO Providers（新的FDO Provider） - Help save time & effort by directly accessing the data you need in their original formats. 快速无需转换的访问多种数据格式
