I have created some Precast concrete pipework and Circular Manholes in accordance with BS5911 (See attachments), these all have the wall thickness for the pipes and the total wall thickness (Wth + 150mm concrete surround) built in.

The pipework works fine but there seems to be some kind of bug with the manhole sizes, they seem to be displaying the overall diameter slightly smaler than it should be.

In most cases it's 65mm less than the actual diameter, can anyone see why this could be? I have set it up as SBSD = (inner diameter + Surround * 2) but it does not seem to like it at all.

It could be something else such as a style issue.

Cheers
