How to request values of custom properties in gdl?

talmacsi_petrolterv — Fri, 16 May 2025 15:37:00 GMT

I can request the list of all custom properties:

n = REQUEST ("PROPERTIES_OF_PARENT", "", parentProperties)

This gives the guid, GroupName, PropertyName. So I know the basic info about the required property.

But the value request requires "id", here:

mm = REQUEST("PROPERTY_VALUE_OF_PARENT","id",4,0,0,kod)

If I put the guid there, it shows an error message.

I cannot find any other approach.

Or maybe the "PROPERTY_VALUES_OF_PARENT" would be good, but that uses DICT dictionaries - and in the gdl reference guide you can't find proper examples of how to use those dictionaries.

And actually, the opposite direction would be good also: to get the gdl parameters in custom properties.

Just checking, are you creating a custom label or requesting the object's own properties?

Yes, it's some kinda label, but an archicad object (not label-tool).

I can retrieve the gdl (standard / global) variables, but I just want to get the custom properties, too.

Sorry, the answer above/below was also by me. (just missed the right browser)

If its not a Label it can not access custom properties.

As @runxel wrote, objects can’t access custom properties. The workaround is to create a custom IFC translator which maps the properties to IFC properties and these can then be queried with APPLICATION_QUERY command. I think the translator has to be set as preview translator.

The only way is to go around purely in GDL is: with save to txt the property (eg in ui script) and then load it in parameters script, but needs to be triggered.

Managed to implement your suggestion. Thanks! It works just fine.

Almost. Because you have to refresh the object to update properties (in some cases).

I can refresh them by selecting all the occurencies of the element on the active view, open & close the settings of the objects.

Do you know any other way to automatically refresh the objects?

'Rebuild & Regenerate' (CTRL + ALT + SHIFT + R on windows) is the most powerful rebuild command.

Not sure if that will update the properties or if you still need to open the object settings.

Nope. Unfortunately.

But the object works, after all; and updates with opening.

If your script to request the values is in the parameter script of the object, I think you have to open the object to force the parameter script to run.

But there is a command you could add to a menu or toolbar in your Work Environment.

That might work?

I takes a little while to run though.

Or maybe have the script in the Master script and the rebuild & regenerate might work (I am not sure about that one).

It works well. Takes a quite while; but works. Thanks!

The master script workaround is a little bit misterious to me. Never used. The gdl reference guide is not so helpful to me. Do you know a good, comprehensive summary about it?

No, sorry.

It is just the master script is always run, even on a screen refresh I believe.

The parameter script is only run when you change a parameter, i.e. open the object settings.

Most things in the parameter script work in the master script as well as far as I know.

Would you mind sharing the Master Script and the 2D Script? I'm with the same problem but can't solve this.
