We can use the dopfield expression to fetch data from the sub data's child components (Like Basic and Options), Example:

dopfield(“.”, “$OBJID”, “Position”, “Options”, 0, “ty”)

But how is it possible to fetch data from the sub data itself (Like Position from a RBD object or Geometry from a RBD packed object). Attributes like position, and attributes created from sops is stored here.

From a data structure point of view, is there a difference in the data stored on the “Basic” and “Options” records that is children of the different entries of an object like a RBD Object vs. the data stored on the sub data like Position itself?


Another thing, the sub data's record data is called “fieldName” as the parameter name for the dopfield function, but is listed as “Properties” in the geometry sheet. Are they called fields, in DOP or is it just a reference to a property as a “property field”?
