Pressure network IFC export problem

[adam.krug]

What should I do to properly export a pressure network?

Currently I use IFCEXPORT command with default IFC2x3 settings but when I open my exported IFC, I see fittings but pipes are gone.

I'm using Civil3d 2019.

Interesting, did you do the extract solids from pipe network command before the export?

[adam.krug]

No I didn't. Is it required?

Yes, you may use that command (ConvertTo3DSolids) to export your pipes to solids. Also it's recommended to use PropertySetDefine to your 3D solids (to add property of your solids from your pipes data). IFC don't support Civil's pipes ... in IFC 5.0 as stated it will be perhaps

thanks @georg.grebenyuk - works now.

@georg.grebenyuk , How does one actually use PropertySetDefine to  3D solids to add property of your solids from your pipes data?  

Is there a workflow that uses pipe network data and converts it object properties?

Thanks,

Michael,

As I know, User create new empty PropertyDefineSets and write to them property from object [f.e. pressure pipes]. Option or solution that will done it automatically may be do only with programming\dynamo... I don't competent in customization, sorry.

May be other experts can say more about automatisation that process.

I don't know if it works for pressure pipes but I had a similar issue and tried some of these workflows. MAybe they will aid you as well?

I played around with dynamo for civil and I can definately say it was simpler to understand and control than controlling propertysets in a dwg with VBA-code (the links I provided in a previous post discussed this approach). This is ofc only my personal current opinion. I was able to create a script which by a few clicks generates solids with the wished pipe properties as extended date (property sets). This for both structures and pipes. The property sets need to be predefined in the dwg, but once you've done this it is a fairly straight forward process...

With a little tweaking I got the same data as an excel export. I strongly suggest trying dynamo if you have access to civil 3D 2020. The package you will need is the autodesk civil3dtoolkit.

H, Autodesk,

I found "EPN" Command on Civil 3D Autodesk forum Screen Cast, it seems developed by Autodesk developer Paolo Serra.
"CivilConnection - Civil 3D Pipe and Pressure Pipe Networks in Revit" by Paolo Serra.

As per my understanding it attaches required Civil 3D pipe/pressure network properties in Property Data Set.
And Revit Plug-in, which imports that Civil 3D file to Revit with Civil 3D properties as Parameters. 

No information found in that video that where we get this EPN command and Revit Plug-in

I am suggesting that Autodesk should come with Built-In Command that will attach Civil 3D properties to respective property dataset, which are relevant to IFC fields, and should be automatically refreshed when any changes in the network.

Raj
