Lesson 1: Convert Drawing Layers to Feature Classes

The Autodesk SDF format supports a schema that can include multiple feature classes within a single file. In this tutorial, you create an SDF file with a schema whose feature classes reflect the layer structure of a drawing file. Each layer in the drawing file becomes a feature class in the SDF file. Each feature class has properties that match the object data fields for the original layer.

Converting drawing layers to feature classes involves the following steps:

• Examine the original drawing layers.
• Examine the original object data.
• Export the drawing layers to the new SDF file.
