How Do I Turn Off Constraints in AutoCAD?

by

AutoCAD is a powerful software used by architects, engineers, and designers to create precise and detailed drawings. However, there are times when you may need to turn off constraints in AutoCAD to have more control over your drawing. In this tutorial, we will explore different methods to disable constraints in AutoCAD.

Method 1: Using the ‘Dimconstraint’ Command

If you want to temporarily suspend all constraints in your drawing, you can use the ‘Dimconstraint’ command. Follow these steps:

  • Step 1: Open your AutoCAD drawing.
  • Step 2: Type ‘Dimconstraint’ in the command line and press Enter.
  • Step 3: Select the objects that have constraints applied to them.
  • Step 4: Press Enter to confirm the selection.

This method will remove all dimensional constraints from the selected objects, allowing you to edit them freely without any restrictions.

Method 2: Disabling Constraints Individually

If you only want to turn off specific constraints instead of all of them, you can do so by following these steps:

  • Step 1: Open your AutoCAD drawing.
  • Step 2: Select the object that has a constraint applied to it.
  • Step 3: Right-click on the object and select ‘Show All Constraints’ from the context menu.
  • Step 4: In the Constraints palette, locate the constraint you want to disable and click on its checkbox to turn it off.

By disabling specific constraints, you can maintain the integrity of other constraints while having more flexibility to modify the selected object.

Method 3: Using the ‘CONSTRMODE’ System Variable

If you want to permanently disable constraints in AutoCAD, you can use the ‘CONSTRMODE’ system variable. Here’s how:

  • Step 1: Open your AutoCAD drawing.
  • Step 2: Type ‘CONSTRMODE’ in the command line and press Enter.
  • Step 3: Set the value of ‘CONSTRMODE’ to 0 and press Enter.

This method will turn off constraints for all future drawings as well. If you want to enable constraints again, simply set the value of ‘CONSTRMODE’ to 1.

In Conclusion

Turning off constraints in AutoCAD provides you with greater control and flexibility when working on your drawings. Whether you need to temporarily disable all constraints, disable specific ones, or permanently turn them off, these methods will help you achieve your desired results.

Remember, understanding how to manipulate constraints is essential for efficiently using AutoCAD and creating accurate designs. So make sure to practice these techniques and experiment with different scenarios to master this aspect of AutoCAD!
