The attached ipt file is a model of a standard Saint Gobain Water pipe fitting (Flanged 400 Radial Tee). I have modelled it about 6 times in slightly different ways and the same error occurrs every time.
I start by revolving the curved section ant then adding short straight sections to both ends. I then extrude the long straight section through the curved section from one end of the curved section.
There is a gap in the model where the end of the curved section meets the straight section (you can even fillet it as I discovered by mistake). Surely this has to be a bug. Another irritation is that where the two sections meet there should be a 27mm fillet and IV cannot do this. The reason is probably that the fillet blends to nothing but this is a fairly standard requirement.
Any words of wisdom would be welcome.
