Undefined stereochemistry: simple wavy bond instead of wedged wavy bond #1682

Open MichelML opened 2 years ago

Is your feature request related to a problem? Please describe. The use of wavy wedge bonds may create some confusion when compared to the actual dashed 'down' stereochemistry bonds: image

Describe the solution you'd like It may be preferable to replace the edged wavy bond with a simple wavy bond as common in many other chemistry sketcher software: image (1)

My computational chemist colleague @fransu86 suggested the idea

Hi @evgeniiFrolov1 ! A small clarification on our request. The idea to have the wavy bond depicted as a line (fourth case in the figure) instead of a 'wedged' shaped wavy bond does not change the stereochemical meaning of the bond itself but it is a more common depiction used by chemists - essentially it's more a stylish request. Wedged wavy bonds (undefined stereochemistry) can be easily confused with dashed bonds (stereochemistry "down").
