Hi Graham -

Your file doesn’t contain any geometry that can be used to cut out a crater. It does look like, however, that it contains the result of a Boolean operation between a cone and a surface. If you used the BooleanDifference command, the result might look like a union, but that is because the surface is open and the normals are pointing in.
