Note: This function is deprecated. For dimensions or reference dimensions, if owner feature is in group, group feature is returned which isn't the originally documented, inteded behaviour. Use ProDimensionOwnerfeatureGet() to get the owner feature that directly owns that element. Obtains the feature that owns this dimension. For dimensions or reference dimensions in annotation elements, this will return the annotation feature that owns that element, but if the owning feature is in group, it will return the group feature instead
