Sheetcam doesn't see outer line of drawing

I’m not sure what’s going on, but on my drawing from autocad. I draw them in 1 layer, export them as a dxf file. Open it up in sheetcam but now for some reason, it doesn’t recognize to outer line of the part.
Any help would be greatly appreciated

Double-check the layer and make sure it doesn’t have any breaks. I turn all of mine into shapes.

it was drawn in AutoCAD as a circle. Sheet cam just doesn’t see it now.
I opened a previous drawing from 2 weeks ago that i was cutting parts with and it’s showing the same thing, doesn’t see the outer line.
To the best of my knowledge, no setting were changed
