How to Delete Part of a Circle in Fusion 360?

Understanding Circle Manipulation in Fusion 360

Working with circles in Fusion 360 often requires modifying or deleting specific parts to achieve the desired design. Here’s a detailed guide on how to delete a segment of a circle within your design.

Step 1: Access the Sketch

To begin deleting part of a circle, open the sketch containing the circle you wish to modify. Locate the sketch in the timeline or browser panel on the left side of the Fusion 360 interface. If the sketch is incorporated in a component, be sure to expand the component folder to find it.

Step 2: Activate Edit Mode

Once you have identified the relevant sketch, right-click on it and select "Edit Sketch" from the context menu. This action will take you into edit mode, allowing you to make changes to the geometry contained within the sketch.

Step 3: Select the Circle

Take a moment to identify the circle you want to edit. Click on the circle to select it. If the circle is part of a larger pattern or set of sketch entities, ensure that only the desired circle is highlighted for manipulation.

Step 4: Choose the Trim Tool

To remove any unwanted sections of the circle, activate the Trim tool from the Sketch dropdown menu in the toolbar. You can also find this tool on the right-click context menu. The Trim tool allows you to cut away portions of the circle simply by clicking on them.

Step 5: Delete Unwanted Sections

With the Trim tool active, hover over the section of the circle you wish to delete. Once highlighted, click on that segment. The Trim tool will erase that specific part of the circle, while leaving the remainder of the circle intact.

Step 6: Finish the Sketch

After trimming the circle as needed, you can finish your modifications by clicking on the "Finish Sketch" button located in the toolbar. This step exits edit mode and returns you to the main workspace, updating your design to reflect the changes made to the circle.

FAQ

Q1: What if I accidentally trim the wrong part of the circle?
If you make an unintended trim, you can undo your last action by using the Undo command (Ctrl + Z on Windows or Command + Z on Mac). This will revert the last change you made.

Q2: Can I trim more than just circles?
Yes, the Trim tool in Fusion 360 can be applied to any line or curve within a sketch, not just circles. It’s a versatile tool for modifying various types of sketch entities.

Q3: Is there a way to permanently remove a circle instead of just trimming it?
To completely remove a circle from a sketch, you can select the circle and press the ‘Delete’ key on your keyboard. This action will erase the entire circle rather than just a section. If you wish to keep a part of the circle and remove only specific segments, use the Trim tool as described above.
