Easily create and use templates with the upgraded Templates widget in ChemDoodle 2D v12.10.

Executive Summary

Version 12.10.0 is a feature update for ChemDoodle 2D. Major additions include a much more powerful and easy to use Templates widget and system, an updated UNO plugin for round-trip editing with the latest LibreOffice builds on Windows, macOS and Linux, and new settings for finer control over drawing functions.

Additions

  1. The Templates widget has been redone and is much more powerful and easy to use. Management of templates and sets is now performed directly in the widget, and the disparate menu items have been removed. A template may now be composed of several different molecules and shapes. Many of the template sets have been enhanced with better organization and improved drawings. New templates include Newman projections and sawhorse projections. Please see section 3.7.11 of the ChemDoodle user guide for more information.
  2. A new updated UNO plugin (v2.0.0) for round-trip editing support with the latest builds of LibreOffice. Now works on Windows and macOS, as well as Linux. While functionality is still available with OpenOffice, we are no longer testing OpenOffice. Please see section 16.7.5 of the ChemDoodle user guide for more information.
  3. A new setting (Settings>Controls>Bond Angle Increment) has been added to draw in 15 degree incremements outside of the optimize zone. You can now more easily create chair conformation diagrams. This is the default value and you may switch back to the 30 degree value.
  4. A new setting (Settings>Appearance>Show Drawing Measurements) has been added to always show relevant drawing statistics when using the drawing tools regardless of whether angles or lengths are fixed or not.
  5. A new style is added (Styles>Shapes>Pushers>Nucleophile Hint) to render the bond-to-independent-atom arrow shortcut as bouncy, with a dashed line (Marvin-style), or with the Cambridge swoop.
  6. Changing the type of file viewer in Settings>Save Settings no longer requires a restart of the application.
  7. Improved support of MarvinSketch MRV files, including MRectanglePoint subobjects in polylines, read/write of MEFlow pushing arrows, and shape line and background color support.

Fixes

  1. Improvements to the electron pushing results function for single electron pusher cases.
  2. Fixed issue where "N2O4" expands to H5N2O4 because N2 is also an abbreviation and therefore it is not recognized as a formula which would avoid H addition. This abbreviation has been added, also as "NTO".
  3. Fixed bug where expansion of a repeat unit, then undo, then copy and paste resulted in a structure without the repeat unit and missing atoms and bonds.
  4. Fixed unintended stereochemical configurations created when reading InChI undefined and unknown stereochemical flags.
  5. Read of beautified cwc.js files is now possible.
  6. Reviewed round trip editing functionality for iWork applications and updated user guide, as it is now functional again.
