How to link object in floor plan with object in elevation

[Anonymous]

Hi,

I want to link one object in floor plan with another object in elevation using following function.

GSErrCode LinkTwoElements(API_Guid elem1Guid, API_Guid elem2Guid)
{
     return ACAPI_Element_Link(elem1Guid, elem2Guid, 0);
}

If I pass elem1Guid from floor plan and elem2Guid from elevation I am getting APIERR_BADINDEX error.

I want to link these two elements such that if I delete one another one needs to delete.

Please any one help on this please.
