  • Modified: account of sign variability for automatic generation of DCL coefficients.
  • Modified: presentation of soil pressure diagrams (Ry and Rz) for bars.
  • Modified: images from Graphic Organizer are saved correctly (error was found for Windows Vista only).
  • Restored shortcut keys in the mode of arbitrary plane triangulation ('Triangulation' dialog box, 3rd tab).
  • Added: automatic generation of exterior contour in the modes of 'Triangulation of plane contour' ('Triangulation' dialog box, 2nd and 3rd tabs).
  • For 'Dynamic plus' problems, it is possible to open 3D window from the mode of analysis results evaluation.
