AutoCAD 2019 Essential Training: Direct Distance Entry (DDE)

Overview

• Focus of this lecture is on Direct Distance Entry (DDE) in AutoCAD 2019.
• DDE is a method used to draw accurately by specifying distances and directions.

Key Concepts

What is Direct Distance Entry?

• An input method to specify exact distances directly in the drawing interface.
• Useful for precision in drafting and designing.

Benefits of DDE

• Increases speed and accuracy compared to other input methods.
• Reduces errors by allowing direct input of measurements.

Using Direct Distance Entry in AutoCAD

Steps to Use DDE

1. Activate a drawing tool: Initiate a line, polyline, or any drawing command.
2. Point in the desired direction: Use the cursor to indicate the direction of the drawing.
3. Enter the distance: Type in the exact measurement you want the line or shape to cover.
4. Complete the command: Confirm or continue as needed to complete the drawing.

Practical Applications

• Particularly useful in architectural and engineering designs.
• Helps in creating precise layouts and dimensions.

Tips for Effective Use

• Ensure drawing units are correctly set to match the scale of your project.
• Familiarize yourself with the interface to efficiently switch between tools and commands.

Troubleshooting Common Issues

• Inaccurate inputs: Double-check that the units are set correctly.
• Cursor alignment problems: Recalibrate or check mouse settings if necessary.

Conclusion

• Direct Distance Entry is a valuable tool for improving the accuracy and efficiency of your designs in AutoCAD.
• Practice using DDE to become proficient in its application in various design scenarios.
