Proxygraphics Variable In Civil 3D
The video discusses the importance of setting the proxy graphics variable in AutoCAD Civil 3D to one when saving or exporting drawings to ensure proper visualization in Business Center. When proxy graphics is set to zero, imported drawings appear as unusable boxes, lacking detailed information. Setting it to one retains useful data such as contours, corridors, and pipe networks, although some 3D information like feature line elevations may be lost. The video also highlights the export option in AutoCAD Civil 3D, which, especially from the 2020 version onwards, preserves 3D elevations of feature lines, making it a preferred method despite potential issues in earlier versions. However, exporting can result in the loss of curved geometry. The video suggests using a combination of CAD objects and LandXML files for comprehensive design data. It emphasizes the need for displaying elements like triangles and contours before exporting to ensure they are included. The choice between saving with proxy graphics set to one or using the export option depends on the specific data requirements, balancing between retaining 3D data and maintaining geometric accuracy.
