GML2IFC translation/conversion warnings

 

I created a very simple model where I added a GML reader and I want to transform it to IFC.

When I run it, numbers appeared on the connectors. These numbers match with the number of features per feature type. I would assume that the transformation was made, although a couple of warnings appeared during the run of the model (see second image)

 

Nevertheless, when I look for the transformed files, there is nothing on the folder. When I try to inspect the resulting data using the eye, a windows pops up asking for information that was set when i first set the "writers/translator" (see third image) and when I look for the data, nothing was done.

 

I checked about these “warnings” among the FME community, and between not-updated information and broken links, there was nothing there that could help me to find out the reason or meaning or ground for this issue.

I have also checked in https://support.safe.com/hc/en-us/articles/25407793929229-GML-Writing  and here https://support.safe.com/hc/en-us/articles/25407506592653-GML-Reading but unfortunately I cannot solve my problem

I am using the version FME(R) 2024.0.1.0 (20240328 - Build 24202 - WIN64).

Thanks

IFC writing is a little more complex. You will have to write data to a couple of proper IfcClasses to get this working.

Check this tutorial to get started: https://support.safe.com/hc/en-us/articles/25407715698317-AutoCAD-to-IFC-Conversion-Example

The link from @jasperwis helps you to convert the data, but please read the documentation of the IFC-Reader as well. the actual version does not support all IFC-Entities, so you may have to be creative with the ifc syntax.

Thanks for the reply but as you already said, working with IFC it is complex. The IFC to GML does not work in the same way as GML to IFC. I already tried to do it based on IFC to Geopackage link  (which is the model I showed in my question). The rest of examples I’ve been through are not very useful either. I have to emphasize that I am a newbie on the use of this software as well as on this type of data.  If you have something more specific, like a print screen of a model made in IFC, that shows a IFC to GML flow, would be very  very very useful.  Thank you
