Hi, I'd really like to know how to prevent ChemDraw from automatically numbering the carbon atoms in molecules brought in using the Name to Structure function. It's particularly annoying because when I delete the numbers and then move or edit the molecule in any way, the numbers reappear! |

@Agent K7 — File > Preferences > Building/Display > untick: Display IUPAC Atom Numbers on S2N/N2S To make sure the change sticks, open your default style sheet and re-save it with this change in Prefs. Close CD and then reopen it to make sure the changed setting is retained in the default style sheet. A.J. D'Ambra |

Make sure that the "Display IUPAC Atom Numbers on S2N/N2S" checkbox (in the Preferences dialog box under "Building/Display") unchecked. You will get more information from the following FAQ. ------------------------- - PKI Support |
