Beginner question

[dsage]

I'm making this box to be 3D printed. I want to fillet the corners UNDER the lid supports as shown in the corners inside the box. The fillet would be between the side of the box and the underside of the support. The fillet is necessary to eliminate the requirement for support material. BUT how do I access the underside of the supports. they are not accessible by manoeuvring the box.

Option 1: Use the wireframe display mode and then select the edge you want to fillet using the advanced selector with right-click.

Option 2: Generate a section view from inspect, as if you were cutting the part, and you will then be able to easily see and access the interior geometry.

Great suggestions. I'll give them a try. Certainly more elegant than what I came up with while waiting for your response. I just blew an opening through the bottom of the case with an extrude cut. Did the fillets and then deleted the opening.
Thanks
