Capture Walk-through 2: Creating Parts
This walk-through demonstrates several ways you can create and add parts to a Capture library. After you complete this topic, you will be able to:
- Copy library parts and paste them into a new design library
- Rename and edit a library part
- Create a new part and add it to your design library
To follow the instructions presented in this tutorial, continue using the design you completed in Capture Walk-through 1 or use the included design file, CAPTURE TUTORIAL 2_CREATING PARTS.DSN under the ‘materials’ tab.
