Without more details and information it's impossible to narrow it down to the actual cause of your problem.
Check if your pipe has all the features it needs as well as it's design table
Check your fittings if they have all the features it needs as well as their design tables.
Seeing that in your example you only used T's and not once a flange kind of indicates that you are at a loss and most likely have no training in the field of piping.
Please read up about Routing or even better see if you can get a course from your VAR.
Routing isn't like sheet metal or weldments, where even if you don't know the first thing about that line of work you can create something which at first glance might be acceptable. Not even if you have an actual piping background there is lots of things that one needs to learn and find solutions for so as to make Solidworks Piping behave.
Peter, the first para of you response is very positive but the 2nd para is not at all. I do not need to mention my piping background as this is just a straight software configuration issue rather than lack of piping and fittings knowledge. However I would highly appreciate it if you or someone else can advise how to configure the pipe routing properties or database to avoid reoccurrences of such issue. I'm also ready to answer any specific question to help those who are willing to support in clearing up this issue.
If the second paragraph sounded a bit harsh then it's because time and time again I see someone asking questions about Routing/Piping because someone's boss thinks that if one has a mechanical background then they can draw piping, not knowing that it's a complete different field with different standards, different ways of doing things and is in fact a highly specialized field.
If you do have a background in piping and for instance know the difference between and the meaning of FOF, TOS, BOP, Exc. Red. BF, random lengths and how to prevent hydraulic shock or why Lyra-bends get used then that's not just great to hear but it will help anyone trying to help you because then we know how to formulate certain things or anticipate further questions or that we won't have to explain why certain things are a certain way.
The Solidworks routing module is a special beast with very particular and at times peculiar rules. If you don't know how to configure pipe routing properties then the question isn't what you don't know but how limited is the knowledge that you do have. This is not meant to be mean or insulting but just to point out that we can't know what you don't know and there for we have no clue what to ask you to help you and seeing that you have no clue what you don't know you can't ask questions with the right vocabulary. Which is why I advised you to read up on it or even follow a course at your VAR, especially if there's no one around that can take you under his wing.
Else the best I can do is advise that you do read the following couple of great succinct articles that covers the basics and should help you figure out what is going wrong or at least bring you up to speed to help you ask specific questions.
Have a nice one,
I can only thank you a lot for the two links attached here, they are very useful and put me on the right track. I wish you had made may day and posted them in the first place as the benefits of the other nice articles do not support or worth the time spent to correspond with them. This is what I would expect from such a great forum and what I would exactly do if I were in your shoes.
Thanks again and much appreciated.
I believe that your Pipe.sdlprt file either lacks nominal size values or has their definitions broken. If you attach your Pipe.sldprt file, then someone with current version may be able to inspect this. That would not be me.
Or provide us something to inspect. A pack & Go of that assembly could also help, as from the image we cannot tell what you have, or how it was done, or what IS working correctly.
I recommend you also read How do I do this SOLIDWORKS Forum thing? . Peter's comments were entirely justified and valid in response to the limited context which you had provided in the original post.
Thanks a lot Tom.
