Sloped Sanitary Pipe

[Stadtler]

What is the procedure for moving a branch pipe (with pipe and fittings) upstream or downstream of the current point of connection on a sloped main?

I cannot seem to move a "group" of sloped piping (getting an error) and really don't want to erase all the branch piping and redraw it in the new elevation/location.

Basic question is - what is the procedure to make changes in a sloped piping system which reflect relocated plumbing fixtures, floor elevation changes in part of the building, and offsets vertical and horizontal for branch piping - in other words, how to handle "REAL WORLD" sloped piping situations where the architectural model changes?

I will be watching this thread because, if someone has a simple way to make these changes I want to know about it.
Now, a couple of possibly obvious things to watch out for.
1. you cannot have any constrained points in the piping you want to move
2. (sim. to above) cannot be connected to the fixtures
3. most importantly, alterations to sloped pipe systems sux

So what you are telling me is that Revit MEP can handle sloped piping almost as easy as OTB Autocad but you have to pay the high premium for the privilege of experience all the associated headaches.

i tried the autocad plumbing package in 2004 but my partner in crime here did not wish to learn it and we were still only creating 2D lines and circle so I abandoned it. I have no knowledge of what AutoCad can do with sloped pipe.
So, what I am telling you is we (I) do not use the sloped pipe in Revit. I had made a few attempts but have not taken a project to completion with sloped pipe. The closest I came to success was by sloping after I was fairly certain that the project was done morphing.

As a work-around, I have found that one can move sloped piping after first grouping it AND linking it. You can then align the group in the horizontal plane as needed and once this is done, bind the group (unlink) and then deal with the vertical alignments. The group as a whole can be elevated (record/note existing elevations prior to grouping at original location and the future location POC) and once elevated, ungroup and tweak the final connection. It isn't pretty but it does work much better than redrawing an entire branch system.

I am still looking to ADSK to fix the issue of sloped piping or at least be a little more up front about what the limitations you will encounter if you look to utilize it.

thanks Stad, I think
i truly believe one of the greatest problems @ ADSK is they don't have a real life, **** on his boots, plumber to help them understand the real world of plumbing installations. it seems that the sloping issues has been a problem always. hope this doesn't sound like sour grapes or whining. just stated the facts from my prospective. i love Revit's potential. i love what i see in hvac, arch and structural.
not part of this thread but, paper CD production is my biggest issue because until we are delivering only BIM digital models and not paper it needs to be easier to communicate to the contractor the construction requirements in a visual format that is at least close to what the construction world is accustomed to.

BTW the starred out word in my last post is not what most would think it is. the word is c-r-*-p. thought that would me allowed sorry augi. i have been a plumber with stuff on my boots and apoligize if I offended anyone.
