In this video we take a deeper look at the Relayer Objects command available in the 3.60 release of Trimble Business Center-HCE. Using this command we will take a PDF that was published from CAD with the Store Layer property toggled off. The result of this is the vector data when imported into BC-HCE ends up on layers based on style rather than their original CAD layers. Using the Relayer Objects command we will demonstrate how to quickly fix and cleanup this data.
