Moving from UPV to UDiTH

Step 1: Prerequisites for the Evaluation/Installation of UDiTH

  • Use a dedicated computer on which no UniversalPlantViewer, UniversalPlantViewer Builder, or Adapter is installed.
  • If UPV models already exist, ensure that this computer has appropriate access to a UPV model for the purpose of initial testing.

Step 2: Accessing an Existing UPV Model Using UDiTH

  • Install the UDiTH Viewer.
  • Create the licence file udithlicense.txt, containing only the UDiTH licence key provided by CAXperts.
  • Copy this file into the \Data directory of the relevant UPV model.
  • Access test: Launch the UDiTH Viewer and open the UPV model using the newly added UDiTH licence key to confirm proper functionality.

Step 3: Updating All UPV Models and Workstations to the UDiTH Viewer

  • Add the UDiTH licence file udithlicense.txt to all centrally and locally stored UPV models.
  • Uninstall the UniversalPlantViewer from all workstations.
  • Install the UDiTH Viewer on all workstations to replace the previous application.

Step 4: UDiTH Capture Station – Creation of UDiTH Models

  • Install the Adapters and the UDiTH Builder in version 2026.X.
  • Open either an Adapter or the UDiTH Builder and activate the UDiTH licence via the Help → Update Licence dialogue.
  • Conduct an initial data conversion test using an Adapter for 3D data (e.g. AdapterForE3D, Ifc, LaserScans, Navisworks, or SmartReview).
  • Perform an initial model creation test using the UDiTH Builder.
  • Open the generated UDiTH model with the UDiTH Viewer to verify successful creation and compatibility.

Step 5: Scripts (Command Line Mode) for Model Creation

  • All model creation scripts must be updated to reflect the installation of the UDiTH Builder and its revised installation directory structure.

Step 6: Updating Additional UDiTH Capture Stations for Model Generation

  • The Adapters (version 2026.X) and UDiTH Builder (version 2026.X) must not be installed concurrently with Adapters or UniversalPlantViewer Builder versions 6.X or 7.X.
  • Uninstall all Adapters and UniversalPlantViewer Builder versions 6.X or 7.X prior to installation.
  • Install the Adapters and UDiTH Builder in version 2026.X.
  • Activate the UDiTH licence using either the Adapter or Builder via the Help → Update Licence dialogue.
