Geospatial features have options in AutoCAD Map 3D 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 (page 309) 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.
Exercise 1: Create a map
Create a map file.
To create a map file
1 Create a map using the map2d.dwt template.
2 Assign a coordinate system to the new map.
■ Switch the Task pane to Map Explorer.
■ Right-click the Current Drawing entry and click Coordinate System.
