My team working on interopreability program is affected by the problem as described below:
In Navisworks 2012 when it opens the ifc file exported from Tekla Structures, there is a GLOBALID property field in IFC tab; however in Navisworks 2013 that field doesn't exist anymore. Our previous wriiten code relies on that field to transfer information betwwen Tekla Structures and Navisworks. I have attached a screenshot for the question. Can anyone help me on this, thanks!
