How do you close gaps in rounded shapes?

Hi all!

I'm very new to fusion 360, and try to teach all these skills to myself. I'm definitely out of my depth currently with a project I'm working on, and need help. In the screenshot, you can seem I'm working on an iron man helmet, however there's a couple of gaps in the forehead of the design. Does anybody know what would be the best way to close these gaps making it be one solid helmet again? Because I'm very lost currently. Thank yoy

Can do you post the f3d file? There are a variety of approaches for this kind of thing, but not all of them will work in every circumstance.

Hi,
There are many possible ways. I think sweep will work in this case.
Thank you.

Yeah sure, attached is the f3d file

In this case, just select the interior faces of the slots and hit the Delete key. Fusion 360 is very smart about replacing deleted geometry by extending the surrounding surfaces.

You can verify that this doesn't cause any subtle deformations of the helmet by doing a zebra analysis (Inspect -> Zebra Analysis).

Two other points

• For this type of project, you should be working in parametric mode. This captures the development of the design and allows you to go back and edit earlier steps. To turn it on, right-click on the topmost item in the browser and pick Capture Design History.
• Your design has an axis of symmetry. So just create the right or left half and then mirror the whole thing across the YZ plane as the last step. That will ensure that it stays symmetric and will minimize the amount of work you need to do.

I cannot believe the answer was the easy, thank you so much. That just made my life a lot easier.
