AVEVA E3D Design Model Extraction

During the model extraction, the COLUmns are the first set of GENSECs that are scanned. Hence their end points and JLDATU are taken as the reference node positions. Following the COLUmns, the BEAMs are scanned and the BEAM end points are merged with the COLUmn reference node positions. The BRACes are the last GENSECs to be scanned. They take reference from the COLUmn and BEAM nodal positions.
