Errors can be introduced into maps in several ways – for example, while digitizing or through inaccurate scanning. You must address errors by using the drawing cleanup tools before you can create topology or perform map analysis. AutoCAD Map 3D has several tools to help you clean up and edit your maps so that they are accurate and suitable for topology, mapping, and plotting.
You can manually clean geometry in a map by using standard AutoCAD editing tools. However, most maps are so extensive and complicated that using manual editing techniques is not only tedious, but is also unlikely to identify every error that needs o be addressed.
The drawing cleanup tools in AutoCAD Map 3D automate many map editing tasks.
