How to Delete Fillet in AutoCAD?

Understanding Fillet in AutoCAD

Fillets are rounded corners or edges in design, essential for enhancing aesthetics and reducing stress concentrations in mechanical components. In AutoCAD, creating or modifying fillets is a key action, especially when precision in drafting is required. However, there may be instances where you need to delete or remove a fillet from your design. The following steps detail how to effectively remove fillets in AutoCAD 2025.

How to Delete a Fillet in AutoCAD

To delete a fillet in AutoCAD, follow these structured steps:

Step 1: Access the Fillet Tool

Begin by ensuring that you are in the relevant workspace of your design. Navigate to the Modify panel in the Home tab. Here, find the Fillet command. If you prefer command line accessibility, simply type “F” to activate the Fillet tool.

Step 2: Select the Fillet to Remove

With the Fillet tool active, you can select the fillet you wish to delete. Click directly on the fillet itself. If the fillet is attached to a complex shape, you may need to click near it or use a selection box to ensure it is highlighted. Make sure the carefully selected fillet is the one intended for deletion.

Step 3: Utilize the Remove Option

Once the fillet is selected, navigate to the Fillet drop-down menu again. You will see an option for “Remove.” Click this option to proceed with the deletion. For command line users, you can type “R” to access the remove command after selecting the fillet.

Step 4: Confirm Deletion

After selecting the Remove option, you may need to confirm your action. Click again on the fillet or use a crossing selection to finalize its removal. The fillet will be deleted, and the remaining geometry will adjust accordingly in your drawing.

Step 5: Verify Changes

Inspect the modified section of your drawing to ensure the fillet has been successfully removed. You may want to zoom in on the area to check that all aspects of the geometry align with your design requirements.

Additional Methods to Remove Fillets

Sometimes, alternative methods might be applicable depending on the context.

Method 1: Delete Command

If you want a quick removal, select the fillet and press the Delete key on your keyboard. This action will delete the fillet without needing to navigate through menus.

Method 2: Modify the Features in the Properties Palette

If the fillet is associated with parametric features, you might want to explore the Properties palette. Right-click on any object near the fillet, select Properties, and adjust the settings related to the fillet. You may find options to reduce or remove the fillet radius there.

Frequently Asked Questions (FAQ)

What happens to the geometry after removing a fillet?

When you remove a fillet, the corresponding geometry will revert to its initial state, typically resulting in sharp corners that can create stress points where two lines intersect.

Can I undo the fillet removal if needed?

Yes, if you accidentally delete a fillet, you can use the Undo command (Ctrl + Z) to revert the action and restore the fillet to its previous state.

Is there a way to revert changes made to multiple fillets at once?

To revert multiple fillets simultaneously, consider using the Undo command or access the History feature if you are working within a step-managed environment. This allows you to step back through multiple actions taken in your drawing.
