The following tools are available to help you quickly find colliding elements in complex models:
CLASHBACK
Import your Autodesk NavisWorks XML collision files into TRICAD MS and MicroStation
This add-on allows you to import your Autodesk NavisWorks XML collision files into TRICAD MS and MicroStation/OpenBuildings Designer.
NavisClashback then verifies that all of the drawings belonging to the collisions have been loaded in MicroStation as a master file or reference file and shows any DGN files that are missing.
Visualize all collisions in MicroStation at once and then edit them. Click on the listed collisions to centre the colliding elements in a predefined view and mark them with a sphere at the collision point.
