Forcing Isometric onto 1 sheet that contains a loop

[Chavez79]

Is there a known bug when forcing an iso onto one sheet that has a piping loop? It will either fail or produce an iso that is unreadable every time. We are running 2014 with extension 2. If someone knows how to get this to work, please let me know. The hand editing is a killer.

Thanks,

Mike

Yes. Loops aren't always generated correctly when shown entirely on one sheet. With normal splitting, they are split so they do draw correctly.

We're working on it.

Is there any update to this bug?  Has it been addressed in 2015?

It is still a bug in 2020 😉 I am experiencing this today.

This is still a bug in 2021. I haven't tested the latest two versions though. 

So how in 2014 "We're working on it." - Autodesk  and in 8 years its still not fixed?

This is a common thing to bypass a large valve with a small bypass to allow for re-pressurization. To get the iso to generate we need to add break points to move the bypass to a separate drawing.

If there is a loop it either fails altogether or it squashes the parts together into an unrecognizable mess. There is also no indication what caused this error, it was only through trial and error we discovered what was causing it. 

We have been using this work around for years, so would be really helpful if we don't need to deal with it.

I switched to Isogen mainly because of this bug and the speed with which drawings are created. At least they do fix bugs for Isogen eventually... but with my life long experience with Autodesk I do not expect any significant number of bugs and problems get fixed.
