Drawings

Show/Hide all C-Atoms

Decide, if all carbon atom labels should be shown

Show/Hide all missing hydrogen atoms

Decide, if hydrogen atoms should be added where possible

Show non bonding electron pairs

Enable or dissable the placement of non bonding electron pairs on heteroatoms.

Set default atom & bond attributes

Switch back to the original attributes for atoms and bonds.

Enable/Dissable position helper

When drawings bonds the position of the bond is locked on some positions

Enable/Dissable warning for to many bonds

Tools

Calculate formula

Calcuculate the chemical formule of an atom selection.

Calculate average mass

Calcuculate the average mass of an atom selection.

Add explicit hydrogen atoms

Adds explicit hydrogen atoms on atoms with free valences. The addition can be restricted by selection.

Remove explicit hydrogen atoms

Removes explicit hydrogen atoms. The removal can be restricted by selection.

Arrange

group

ungroup

separate
