I have created the following shape.
When deleting an edge, the top face is also deleted as expected.
When I draw that line again, Sketch Up creates a face using the outer shape without taking into account the inner one.
It’s not possible to select the area formed inside the inner shape. The only way to go back to the original model is to redraw one of the lines of the inner shape (so that a face is formed) and then I can delete it.
Is this the normal way to achieve this?
