Point Cloud

  • Occasional crashes when adding color schemes to point clouds no longer occur.


  • Occasional crashes when detaching external references in some visual styles no longer occur.
  • Occasional crashes when importing or attaching DGN drawings with some spline types no longer occur.
  • Occasional crashes when getting the UCS coordinate values from a dimension no longer occur.

Several additional defects have been fixed with the following results:


  • The image of a Web URL in the drawing displays correctly.

Model Documentation

  • No error dialog box displays after completing certain Model Documentation commands.


  • The characters show correctly when using double-byte characters with certain settings.

PDF / Plot

  • PDF files plotted using certain visual styles display correctly.
  • The plot result remains correct after changing the visual style in model space.


  • Object snap settings remain turned on during view editing commands.
  • AutoCAD startup time and network drive scanning speed are improved.
