Hi,
I'm trying to define our work flow for OPM at the moment and I've found something I would call a bug in OPM SS6. Due to the size of our piping model, I've determined it's best to have each pipeline in its own model. So essentially, in a design file, there'll be multiple models. Each model will have 1 pipeline defined and modelled in it.
For example, say my DGN file has 2 models: A and B. Model A has pipeline X defined and modelled inside it, and model B has the definition and model for pipeline Y. So when I switch between model from A to B, I would expect the standard preferences dialog to update the pipeline list accordingly in its dropbox. However, that's not the case, the standard preferences dialog still has pipeline X as the active pipeline. Meaning now I'm in model B and the active pipeline is still X.
So when I proceed to place any piping component, an error message would show up. The component can still be placed, but it is now assigned to the pipeline X, instead of Y, and hence doesn't appear in the Pipeline Manager dialog, which only shows pipeline Y as is the case for model B. Below is the snapshot of the error message.
So everytime I switch models, I have to restart the standard preferences dialog, which is really a drag. Can someone from Bentley take a look at this and advise if there's anyway to fix this bug for SS6? I can confirm that this is reproducible in standard OPM build using Bentley delivered spec.

Hi Tuan,
Unfortunately, we do not support multiple models in the DGN file in OpenPlant Modeler. If you want to break the model, then you will have to create separate DGN file and then attach it as a reference file into master DGN file.

Hi Harpreet, I think we can live with 1 DGN per pipeline. However, how would I go about having the correct connection details in the following scenario: Say pipeline A is connected to pipeline B. So in pipeline B model, pipeline A is referenced in and used to create the bolt and gasket which are part of pipeline B. Since pipeline A doesn't have any reference to pipeline B in the first place, so it won't know that it is connected to pipeline B. I can reference in pipeline B, replacing the connecting flange (moving existing flange doesn't seem to create connection to referenced pipeline). But then OPM will add another set of bolt and gasket for pipeline A, essentially doubling up on bolt and gasket. Any suggestion?
By the way, is there a sample workflow that considered best practice that I can refer to? Best regards, Tuan
You can cross-reference both DGN files i.e. reference DGN A to DGN B and vice versa. To create a connection between two pipelines modeled into two DGN files you need to follow the steps below.
Like this you can maintain connectivity across the different models.
Hope this helps!
