  3. Start a new Civil 3D drawing from acad.dwt of other template (you may have a template with preloaded styles, settings)
  4. In Settings tab, assign coordinate system, units and scale identically as from your original drawing
  5. * Optional: Run IMPORTSTYLESANDSETTINGS command to import all your styles and settings from your original drawing
  6. Then Insert (Explode upon Insertion) the WBLOCKED file you created in step 2
  7. To get your layout tabs you right-click on layout tab in the drawing and used “from Template” option to import DWT or DWG file. Choose your DWG file. – This will insert layout tabs into your drawing
