Which Mapping Products Are “Better”, ESRI’s Or Autodesk’s?

I’ve heard the question many times, and I’ve heard a lot of answers. “ESRI’s products make inaccurate maps”, claim some AutoCAD users, while some ArcGIS users feel that “AutoCAD ruins our coverages”.  In reality, BOTH families of products are excellent for certain tasks, and not so good for others, but the gap is closing and […]

Converting & Tracking Map Coordinates

If you are using Civil 3D or Land Desktop, it includes a version of Autodesk MAP, which provides a number of methods for dealing with digital maps from multiple coordinate systems. In addition to a wide variety of advanced import and export features, MAP 3D also provides the ability to convert coordinate systems through queries, automatically converting […]

Thematic Mapping

With the introduction of the Display Manager in Autodesk MAP 3D 2005, you now have a better way to create thematic maps from your AutoCAD drawings.  A thematic map uses properties like color and line width to display objects by data classifications. An example of this is a map of pipelines where you use different […]

Trimming and Breaking Objects

At one point or another, we are all faced with the tedious prospect of breaking or trimming a lot of drawing objects on different layers.  TheMAP > TOOLS menu offers two great utilities to make these tasks easier: Boundary Trim and Boundary Break.  The dialog boxes that control these two tools are very similar. This tutorial shows how Boundary Trim works. Simply substitute […]

Save the Current Map as a New Drawing

One of the many powerful features of AutoCAD Map 3D is Thematic Mapping, which allows you to quickly alter the way AutoCAD objects appear.  For instance, you can use it to display all of the lines on a sewer pipe layer using different colors, representing the size of each pipe. A major benefit of Thematic Mapping is that it does not permanently […]

Vexed by 3D Polylines?

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 […]
