How can a monomer be removed from the HELM monomer user library in ChemDraw 20? The monomer editor seems to allow only for the addition of new monomers.

  Select the Monomer library that you want to remove and click the "Deprecate" button

  Hi, I cannot find this button, only "Add New". This is ChemDraw 20.0.0.41

  This feature was introduced from v21.0 so  we recommend using the current version.

  We are not sure about the product for which you have a license. If you have a subscription license then upgrade to the current version.

  You need to select  "Show HELM Monomer Toolbar" from the View menu and then click the Manage Monomers button.

  
   
   
  
   
  It will open the following dialog box, select the Library as User and the desired Type and finally select the Monomer library that you want to remove. Then click the "Deprecate" button
