Cut Selected

Removes the selected part from the model.

Select all

Selects and marks all atoms in the molecule, so that it can be rotated, moved, deleted, etc. This is the only chance to recover parts of the molecule that are outside the display area - select all, go into move mode and move the molecule using a visible part of it.

Hydrogens

Add Implicit Hydrogens

Selects and marks all atoms in the molecule, so that it can be rotated, moved, deleted, etc. This is the only chance to recover parts of the molecule that are outside the display area - select all, go into move mode and move the molecule using a visible part of it.

Make Hydrogens Explicit

This will transform hydrogens, which are directly connected to another atom, separate atoms connected by a single bond.

Make Hydrogens Implicit

This will delete bonds to hydrogens and add hydrogens directly to their parent atoms.

Adjust Bond Orders

Sets the order of all bonds so that every atom is saturated.

Reset Bond Orders

Sets the order of all bonds to single.

Clean Up

This changes coordinates of atoms a length of bonds to standard representation.

Model Properties

Changes properties for this frame. Current properties are: author (who generated this model), generation date and software. Additionally, a cas number and checksum can be given.
