How to Regenerate Model in AutoCAD?

Understanding Model Regeneration in AutoCAD

Regenerating a model in AutoCAD is a crucial process for ensuring that all elements of your drawing are accurately displayed. This process refreshes the drawing’s visibility, updates object locations, and improves performance within the current viewport.

What Does Regeneration Do?

When you initiate a regeneration using the REGEN command, the following occurs:

1. Recalculation of Object Locations: The command recalculates the position of all objects within the viewport, ensuring they are displayed correctly.
2. Visibility Updates: Any changes made to objects, such as visibility toggles or layer adjustments, will be reflected immediately.
3. Database Reindexing: It reorganizes the drawing’s database, optimizing object selection and overall display efficiency.
4. Area Reset: The command resets the panning and zooming capabilities, enhancing the navigation experience in the viewport.

How to Execute a Regeneration in AutoCAD

To regenerate your drawing, you can follow these steps:

1. Using Command Line:

   • Open AutoCAD and ensure your drawing is active.
   • Type REGEN or RE into the command line and hit Enter. This will trigger the regeneration.

2. Using Menu Options:

   • Navigate to the View menu.
   • Select the Regen option from the dropdown list.
3. Using Toolbar Buttons:
   • Locate the Regen tool on the View toolbar (identified by a specific icon).
   • Click on the icon to activate the regeneration process.

Navigating Common Issues with Regeneration

Sometimes, you may encounter scenarios where regeneration does not perform as expected:

• Check Display Settings: Ensure that hardware acceleration settings are compatible with your system.
• Update Drivers: Outdated graphics drivers can interfere with the rendering process.
• Inspect Drawing Integrity: Verify that the drawing does not contain corrupted elements, which could hinder regeneration.

Controlling Automatic Regeneration

AutoCAD typically regenerates drawings automatically when changes are made. However, you can manage this feature to optimize performance:

1. Disabling Automatic Regeneration:

   • Type REGENAUTO into the command line.
   • Set the value to OFF to turn off automatic regenerations.
2. Manually Triggering Regeneration:
   • Whenever necessary, you can manually trigger regeneration using the steps outlined above, allowing for greater control over performance.

Recovery of Drawings in AutoCAD

If your drawings become corrupted or are not displaying correctly, AutoCAD offers commands to restore them:

1. Using the Recover Command:

   • Enter RECOVER in the command line.
   • Select the affected DWG, DWT, or DWS file and click to open. AutoCAD will attempt to repair the drawing automatically.
2. Accessing the Drawing Recovery Manager:
   • Open the Drawing Recovery Manager within AutoCAD.
   • Browse through the backup files and select the most recent version for restoration.

Frequently Asked Questions
