Inventor sketch will only extrude as a surface

[243204]

The DWG file I imported looks like it is an enclosed shape, but the extrude tool will only let me extrude the perimeter as a surface. I attached the file below, so any advice would be appreciated!

Try to run a Sketch Doctor (while editing a sketch) and see if there is a report on Open Loop in there. If there is - close the loop.

Inventor 2022.2 was able to extrude it as a solid (attached), despite issues pointed out by the Sketch Doc:

If I don't want to spend time repairing the imported sketch I try 1 of 2 things.

Try and create a surface patch, which will then give you a closed profile.

Or extrude as surface(s), then stitch the surfaces together, of if there is a large gap then create a new surface to fill it, either from a new sketch of lofting from the 2 profiles on either side of the gap, then stitch.

This will give you a projected closed profile to extrude as a solid.

Or you can patch the 2 ends and stitch to make a solid.

Or, before you import the sketch you can use pedit in Autocad to close the loop!
