3D Polylines can be quite useful, but sometimes you might find them in a map and struggle to use them as 2D boundaries, wishing there was a simple way to convert them to flat polylines. The Drawing Cleanup dialog box in Map 3D and Civil 3D offers a solution. This tool is available from the Tools tab of the ribbon …
Here are a few sources of geospatial data that I have used. If there are any sources not listed that you would like to share, please share them with me and I will add them to this list. Likewise, please report any broken links below, so I can fix them. GIS Pilot http://www.gispilot.com/ Geo Community GIS Data …
When stylizing Feature Data Objects in Map 3D, there is a powerful setting that many users overlook: Scale Ranges. One example of how this setting can benefit you is using it to cause a very detailed set of features, such as a street map or a soils map to only display when that level of detail is useful, …
We’ve all been there. It’s crunch time and you encounter hundreds or maybe thousands of individual line segments that should be continuous polylines. Perhaps they are contours or tax lots, or maybe street center lines. The end points are snapped together, but when you try to select them or perform some operation on them, you …
In our book “Digging Into AutoCAD Map 3D 2011 – Level 1 Training” we cover the basics of Object Data and External Database Links. We explain the differences between these two methods of linking data to AutoCAD objects, and what types of data are appropriate for each. At some point, you might wish to do a little more …
Autodesk has added the capability to access Geodatabases that were created with ESRI ArcGIS 9 products.

Among the many enhancements and changes to AutoCAD Map 3D for 2012 are new workspace ribbons, as well as new interface tools for selecting coordinate systems and stylizing features. The first change you are likely to notice when you launch the latest version of Map 3D is the ribbon. The default workspace, and the one used for …
In AuotCAD Map 3D, when an external database is attached to a drawing, the data is not brought into the drawing file as AutoCAD Mapobjects or data. Instead, the database is attached through a Universal Data Link file. Linking records in an external database to individual drawing objects requires some setup. Much of this setup is a one-time task, …
There are many tools in AutoCAD for measuring distances. With features like Object Snap, it is a simple matter to get a very precise number of units between any two points. But is this precise measurement accurate? As I concluded in a tutorial on Accuracy vs. Precision several years ago, it is sometimes better to be approximately correct, than precisely wrong. …
