Where you are now
You created a new map that uses the object class definition (page 313) file you
defined. You queried in objects to the new map.
To continue this tutorial, go to Lesson 5: Create and Edit Objects Using Object
Classes (page 159).
Lesson 5: Create and Edit Objects Using Object
Classes
You can use object class definitions as a shortcut when you create or change
classified objects. In this lesson, you create and edit objects using object classes.
Exercise 1: Create objects using object classes
When you create a new object using object classification, the new object
inherits the basic properties for its
object class (page 313) with default values
for those properties. You can change the values as needed.
When you query in objects from a DWG file to a map, any styling information
is lost. Since the points are not styled, you cannot see them in your new map.
To see the signal points, assign a point style to your map.
Once the signals are visible, you create a signal using the Signals object class.
NOTE This exercise uses the map you created in Exercise 1: Create objects using
object classes (page 159).
