Hi Jim- I've moved this to the support system. Best to send questions to support-idv instead of me directly so we can better track these issues. Thanks for catching this. Did this ever work? I've always done this as a volume since IPV needs several levels. If you select 2 (or more) levels in the levels panel, you'll be able to do the slice for a plan view. However, the list of levels in the control will not reflect the levels you selected, but the entire list of levels. We're working on a fix to this.
