Is anybody out there placing pipes in fairly close proximity to other pipes? Having the interference rules pop up with errors from time to time? If so, how are you accounting for collars on pipes?
I realise that wherever you maintain your 300mm/12" clearance pipe collars are not an issue. However, in some situations, such as the exsting sewer line upgrade I'm dealing with now, the laws of gravity insist that one places the new pipe as hard up against the underside of another existing gravity line (stormwater in this case) in order to get the fall. Any ideas as to how model this?
TIA,
Trevor
