Create a box around an existing loft/shell object

[jwwhitmarsh3]

I have an existing loft/shell dish shape I am trying to not recreate, and want to add an extruded rectangle below it, leaving the shell as a dished-out portion of the resulting box. One plane is the flat of the loft/shell, and I have an offset plane from there where the box sketch lives. If I try to extrude that box with an Intersect option, it looks like it's going to work, but I end up with no extruded object afterwards. Is there a different way to do what I'm trying to do, or am I stuck recreating the dish shape after creating the extruded rectangle?

Please attach your model.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

You have a body extruded around a body.  After you create the rectangular body, use the Combine command to subtract your body from the rectangular body.  You body was not Shelled so I did it to a 1mm thickness which can be modified.  Model is attached.

By the way, you will be a lot happier modeling in Fusion using Capture Design History.
