Parameters for "Marker Head in the Middle" and "Marker Head at the Ends" for Sect/Elev Markers?

Palawat — Tue, 20 Jan 2026 05:41:59 GMT

Hi,

Is it possible for a GDL marker object ( of Section Marker/Elevation Marker subtypes) to "know" if that Section/Elevation is set to show "Marker Head in the Middle" or "Marker Head at the Ends" ? Any parameter? Thank you in advance.

@Palawat I don't believe so. Although it would be a nice to have.

Thank you very much, @easyDoesIt . Hopefully someone migh have a few tricks up the sleeve. Maybe someone from Graphisoft? 🙂

Looking over the parameters of the Built-in Section Marker, there does not seem to be any parameter that would be able to return this type of information.

Also, I am not aware of any command or function in GDL that would give you this data.

It may be possible to extract this info from the model using the Archicad API, but I am not familiar with it so I cannot tell for sure.

Based on the changes I made to the original marker, I would say it should be the SYMB_MIRRORED variable.

Yes, but SYMB_MIRRORED is only helpful for when the left and the right marker should be distinguished.

Decerning if the user has selected "at ends" / "center" is not possible however as far I'm aware.

Thank you very much, everyone, for the inputs. Maybe I should just go ahead and make a wish.

Cheers!
