  • Feature Display Issue with Explorer after Solids Modification

    I refined the pier cap for the hammerhead on the right using solids modifying tools, and kept the one on the left as unmodified. When I go into Explorer and turn off all supports, the modified cap stays visible, while the column and foundation connected…
  • No Active Bridge is Selected

    I have an OBM model built in a separate 3D file (File A). I referenced that dgn into a new dgn (File B) to create multiple drawing and sheet models. I have created mutliple 'drawing' models within File B with no problems. However, for the past few days…
