Navis Simulate is having the problem of not reading MEP Fabrication (TSI) objects. When we first switched over to Autocad MEP 2013 and Navis 2014 we were able to see the Fabrication items. After the first issues of Navis not reading the Fabrication(TSI) items, the latest object enabler was run on the computer and the objects appeared. About a week later they stop showing up. We then loaded the capmep19x64.dbx into autocad allowing the fabrication objects to be visible. Again about a week later the fabrication objects are no longer visible. Has anyone that works with MEP Fabrication (TSI) and navis simulate or manage had this problem and how were you able to fix it?
