How do I delete all constraints in AutoCAD?

You can delete all constraints in AutoCAD by using the "Delete Constraints" tool within the Parametric tab. Here's how:

1. Select the Object(s): First, select the object(s) that have constraints applied to them. You can select all objects in your drawing to remove all constraints at once by typing ALL at the command line when prompted to select objects.

2. Access the Parametric Tab: Ensure that the Parametric tab is visible in the AutoCAD ribbon. If it's not, you may need to enable it through the AutoCAD customization options.

3. Use the Delete Constraints Tool: Navigate to the Parametric tab, then locate the Manage panel. Within this panel, click the "Delete Constraints" tool. You can also type DELCONSTRAINT at the command line.

4. Constraints Removed: AutoCAD will remove all geometric and dimensional constraints from the selected objects. Note that this command removes all constraints from the selected objects. If constraints still exist, ensure all objects are selected and the command is re-run.
