ChemDoodle 2D - Executive Summary

This update brings further advances to our 2D structure cleaning algorithm and includes the latest ChemDoodle Web Components 9 library. Several issues are corrected, improving the stability of ChemDoodle 2D v10. This update is recommended for all users.

Additions

  1. The 2D structure cleaning algorithm has seen further advancement. Spiro systems are now expertly handled and a better relaxation algorithm is used when there are inevitable overlaps with standard angles and lengths.
  2. Improved rendering of multiple order bond lines in acute angles.
  3. The built-in ChemDoodle Web Components library has been updated to v9.1.0, along with the necessary changes to the component builder.

Fixes

  1. Corrected the application of style sheets with page counts, where a change in page count would cause an error. Page counts are now properties of the document, and not of style sheets.
  2. Fixed double bond spacing value in J. Het. Chem style sheet.
  3. Fixed page size loading from autosaves.
  4. EPS output now properly defines font families with spaces.
  5. Fixed the output of ChemDoodle metadata in EPS, which caused the file to be improperly written on Windows.
  6. Tweaked automatic charge placement when overlaps with label subscripts would occur.
  7. Reduced the Twitter tweet allowed length to 270 from 280. Twitter uses text weight, not character count and this is a safer value.
  8. The DMG icon for macOS is now properly displayed.
  9. Fixed other minor issues reported.
