Lesson 2: Use the Resulting SDF Files

Connect to the SDF file you created and edit the objects in the map as geospatial features.

Geospatial features have options in AutoCAD Map 3D toolset that drawing objects do not have. For example, you can add properties to the feature classes in your SDF file. In this lesson, you add a constrained property. Constrained properties can have only the values you specify: values within a particular range or within a list you specify.

Note: If you import the SDF file instead of connecting to it, the data comes back in as drawing objects instead of geospatial data. Connecting to the data leaves it in its current format.

This lesson involves the following steps:

• Create a map.
• Connect to the new SDF data.
• Add a property.
