Improvements / Changes

  • The Alignments Coordinates by Interval calculations are much faster.
  • Exporting a large number of ASCII or DXF points is much faster.
  • More multi-page calculation results are touch-scrollable.
  • The maximum zoom level for plotting points and shapes was set too low, small-dimension shapes now display larger on the screen.
  • Intersections input forms now retain entered data when a "Invalid Input" error is thrown.


  • Intersections Bearing-Distance would display two possible solutions, however the direction to one or both of the solutions could sometimes be off by 180°.
  • Resolved issues that caused the app to terminate unexpectedly under specific conditions. Affected programs included Subdivide Area by Sliding Direction, Fit Points to Straight Line, Fit Points to Circular Curve, Average Points and Helmert Coordinate Transformations.
