Yup, it might be but we don't know until we ask
It should be, as I said "based on the degrees of arc".
I'm not sure size matter here. If the base of a building is only seen in the background at the size of the cross section of a pipe, it may only need 24 sides. Alternately, if the cross section of a pipe is viewed with such precision that only a few degrees of arc are visible, then it may need 96 sides.
I hope the DWG importer gives you this setting
