Hi @bskim​,

You still need to use the AttributeExposer after extracting the IFC property sets with the GeometryPropertyExtractor, but newer versions of FME have made this much easier, using Feature Caching.

• In Workbench, choose Run from the top menu, then ensure that Enable Feature Caching is highlighted.
• Add a new AttributeExposer and connect it where desired, then run the workspace to populate the caches, ignoring the incomplete transformers warning.
• Edit the AttributeExposer, then click the Import button at the bottom and choose From Feature Cache. A dialog will come up showing all the available attributes on the cached features. I generally choose Select All, then Import.
• Click OK to save the AttributeExposer settings.

Hi @daveatsafe ,​

Thank you for the reply.

By the way, the question is whether there is a way to automatically feature caching when running in the shell, not through the workbench.

Hi @bskim​,

The attributes are always on the features - the AttributeExposer just shows them to you in Workbench. If you want to propagate the different property sets to the output feature when running in the shell, I recommend using the SchemaScanner transformer to generate a schema from the source features, then set the output writer to dynamic mode, using the schema feature to set the output schema.

Hi @daveatsafe​

Thank you for the reply.

I don't understand the answer you gave to solve the problem.

May I ask for an answer based on the attached fmw?

Update workspace for dynamic output.

Hi @daveatsafe​

I remain deeply grateful for what you have done.​

​Best of luck for your future!

Hi @daveatsafe (Safer)​ 

There is a problem that material files are not created intermittently when converting IFC files to OBJ.

This happens about once or twice out of 10 attempts.

No exact reproduction pattern was found.
