Relations - Does the exists condition work for parameters existing in the material file?

[BillRyan]

I can't seem to get this condition to work.

IF EXISTS(material_param("MTL_MATERIAL_SPEC"))

MATERIAL_SPEC=material_param("MTL_MATERIAL_SPEC")

ENDIF

I'm starting to think the software is not capable of checking for existence of parameter in the mtl file.

If anybody has an alternate Condition / solution to make this work, let me know.

I think by parameters it means only such entities defined in a part or assembly. A material file is neither so this function is not valid for it.

Yeah, I think the only solution is to have some j-link app running in the background to populate the material file attribute when it is missing...
