Piping set up for multiple drafters

[Anonymous]

We are looking for recommendation for the best practices for setting up piping for a large chemical facility where many drafters will be working on a model.  In the end, we will need to use Isogen.

The facility has few different buildings with multiple floors. 

Is it best to set up all the equipment and create an xref for each piping system, such as Chilled Water?  Or do we create a model for each building floor with multiple piping systems?

It entirely depends on how many people you have on the project, what size of the project etc.

Obviously, the different disciplines would have their own model, so at least one Piping Model, one Equipment and one Structural.

From that, how many designers are on the project? Are you getting one group of designers doing the Equipment and Piping models, and then another group doing the structural?

Lay it out on paper first as a rough draft, and get an idea of how many people to how many models required. Without seeing the project, maybe make one structural model for each building, one equipment model (or two? separate equipment models for each floor?) for each of these buildings, and maybe a couple of piping models for each building?

You don't have to make a different piping model for each service, but its up to you. In my dealings, it was easier to have a piping model for an area with all the services in it, its just easier to route pipe and work out accessways, access to valves etc when they are in the one model.

Thank you.  That is would we have done it in the past with MEP but we have not had to do isogen before.

If we set up a piping model for each floor for say a 5 story building, there are 5 models of piping.  If a chilled water pipe main went vertical and had a tee at each floor, there would be 5 section of the same pipe (one for each floor).  Would they all retain the same line number as the PID?  How would Isogen look at it?  Would it see one pipe or 5 pipe sections?

Thanks

Depends on how you want to Iso it, it can be one line, or you can Isogen each floor separately. If you have a look at my attached images, the first image is one model with pipe in it, and the 2nd model XREF'd into it and attached to the elbow. The lines are numbered the same (9999) and when you Isogen it, it comes out as one, if you want it to.

We have a webinar coming up in a few weeks that might be of interest to you. The topic is large assemblies/models in Plant 3D. We'll be discussing how to streamline a large project for optimal performance in Plant 3D.

Hi Jason,

Im pretty interested in the webinar however...In Australia its on at 3am.

Will it be available as a recording for download the next morning?

I'd be interested in seeing that webcast, but the timezone isn't friendly for me!

HI,

I made a  3 route line in the  same 3D continous  line  and when I use create ISO option , the program made 3 iso ( sheets) but  these not are a logical continuance.

Ex:

Line AD 01

       AD 02

       AD 03

I will must have logical connection like in the square not like in the red connection( made from program).

What is rong?
