ChemDraw Magic 2 - More Tips and Tricks on ChemBioDraw13 (HD with subtitles)

[@PierreMx3]

You're very welcome. I don't know the proper path or directory, but you'll find it under "File"; "Preferences"; Directories tab, and then follow the path that ends with "ChemDraw Items". On Windows you have to turn on the option "see hidden folders", don't know if there'd be something like that on Mac.

Awesome video, thanks for that. I am searching for a function where you are able to change the settings of "Clean Up Reactions" in terms of adjusting the lengths of the arrows. Or can i somehow make all arrows the same length in a document otherwise?

[@PierreMx3]

What you are looking for is not available unfortunately. The Clean-up Reaction feature doesn't have its proper settings and the arrows will adapt in size to the reaction constituents in each reaction step

Me: Just trying to build a simple carboxylic acid in Orgo 1 ChemDrawWizard: draws a random macromolecule from heart in 0.2 seconds This was so helpful I had no idea how much of a skill this would actually be lol

[@IMattHarding666]

good question, i think i completely reloaded chemdraw, selected a new ACS document, then set it to poster, clicked ok, set it back to pages, and my page height and width numbers changed, and they never had before. i saw the configuration was landscape, so saved it as fast as i could, and it worked! so i'm still a bit in the dark as to what i did, but i now have a landscape style sheet :)

[@XcaliberII]

I study physics, but this video is mesmerizing! Having played with it in passing, I had no idea chemdraw was so flexible.

[@PierreMx3]

Thanks for your comments! For what you re describing, you need to select the atoms that look weird to you, and press Ctrl+Shift+C, or right click and go to alignment and select Center. It has to be done atom by atom. If you apply it to all the atoms, some of the displays you are used to - like NH labels - may start looking weird as well.

[@PierreMx3]

The clean-up function doesn't have that feature unfortunately. I would say that ChemDraw is mainly about 2D representations, and that the clean-up function is designed to help visualizing molecules, and it does what it thinks is the best job by stretching the bonds. I mean you can still recognize your molecule this way. If you need a more "accurate" visualization with the rings twists I'd suggest opening the molecule in ChemBio3D and hide the hydrogens for example.

[@PierreMx3]

If you just click and drag a bond between any two atoms far away, that will make a long bond. If it's that complex, you need to do some manual rearrangements with the marquee tool. If you go over a bond and by default press "f" or "b" it resp. brings it forward or sends it backwards. You could just add colors to differentiate them. You have any example in particular?

[@PierreMx3]

You normally don't need to touch the .dtd file, only the xml one. Make sure that in the generic section header there is the line: command id="TOOLMODE" description="whatever" with the proper signs at the beginning and the end. I cannot actually copy the entire string in this post. Let me know if that helps

[@mkpjayatunga]

To access ChemDraw items on Macs, right click on the chemdraw icon in applications, and click show package contents. Click on the folders; Contents>Resources>SpecialPurpose, in which you will find ChemDraw items with the hotkeys file you can edit.

[@PierreMx3]

Hello Matt, I'm guessing that you may have the document type layout to "poster". If that's the case you need to switch it to "Pages", and then redefine it as (for example) 1 and 1. Press ok, then go back to the document settings, and now try to switch to landscape.

[@PierreMx3]

Good to hear! A complete reset does have a Magic power of its own...

Hi Dr.Pierre Morieux, I am very happy after watching ChemDraw Magic videos, more useful information.I am unable to find bio polymer toolbar and some other toolbars use in ChemDraw Magic 2 video. I need a help how to access this toolbar. Thanks.

[@waauu]

Hi Pierre! I am very happy that you got hired by Perkin Elmer! I have a question regarding atom symbols, and would be very thankful if you would take the time to answer it - if you can. When drawing molecules containing two-letter atoms, bonds can be centered on either one of the letters, is there a way to make all bonds centered around a sort of "atom-midpoint"? (It looks stupid with a doubly bonded oxygen sticking out of the R in Re for example). I am using Chemdraw 12. Thank you!

[@wenjingliu2246]

when I draw mechanism, the arrow only curve in one direction, which is not convenient. Also, sometimes it is not very precise on the bond, hope some more improvement on this aspect.

[@PierreMx3]

Very glad I can reach out to physicists! Make sure you also watch the first one for the more technical details that make this software so flexible

[@dangerdackel]

How can you make the disulphide bonds larger. If you have several cya in a molecule and they all need to be connected, the S-S bonds all lie on top of each other, so how do you differentiate?

[@arjungontala2865]

Brilliant! Can you please provide your hotkey doc file???

[@axelkonev]

Some more chemdraw tricks from Pierre, thanks!

[@IMattHarding666]

hi pierre, i cannot get my page to flip to landscape, i click the button through document settings or page setup and neither will work, any ideas? in using chembiodraw ultra 12.0

[@BaoNguyen-ew8pj]

My hydro in NH2 aligned at the right position of the N atom, I would like to stack 2 atoms on each others, how do I fix this?

[@BaoNguyen-ew8pj]

Hey so if anyone has the same issue, try pressing N twice instead of once for auto fill Hydrogen, go to File tab and select apply document setting from.... and choose ACS 1996 and it would be better.

[@IMattHarding666]

unfortunately it wasn't set to poster, it was on pages. i even tried switching to poster and back again, so i don't know what the problem is :(, it's no massive issue, i just would prefer landscape as you get a better view of everything! thanks anyway

[@khoivan88]

Hi, first of all. Your videos are super helpful and thank you so much for that. I would like to ask if you know where is the hotkey file for CBD13 in Mac. Thank you so much!

[@PierreMx3]

Sorry Quintus I can't seem to get the structure with InChiKey resolvers.

[@PierreMx3]

You're very welcome Quintus, glad I could help.

[@kevinburgess1183]

Terrific video presentations, Pierre, thank you. I am a committed Mac user, on ChemBioDraw Ultra (13). I note that the PC version allows users to store as scalable vector graphics files, but the Mac version does not. Does anyone have an idea when SVG formats will come to the Mac version? Also, ChemBioDraw Ultra (13) slows down to a crawl after continued use (needs to be quit then restarted). Any thoughts? Why are n't the Mac versions of ChemDraw supported as well as the PC format?

[@PierreMx3]

That sounds quite weird, and no the hotkeys should be functional regardless of the version. If you have kept a back-up of the original hotkey.xml file I would suggest recreating the command lines by copying and pasting from within the xml. Other than that I don't know...

[@PierreMx3]

Can I ask you what you did?

[@dangerdackel]

Thank you very much. I tried your suggestion out and it is OK. Thanks for the video.

[@md.riadhossainsabuj4679]

I am really so amazed......

[@dhirendrabrahmchari4546]

for joining how to select two bonds to be joined together ? When the second point is selected the first one is removed...

[@PierreMx3]

You need to select both bonds with a selection tool (hold shift) and then press ctrl-j. The first bond selected won't move

[@dhirendrabrahmchari4546]

Now its working ... thanx a lot

[@PierreMx3]

biopolymer display: 15 residues per line and block, write sequence, draw S-S bonds between proper residues, select expand. Shift and double click each aa letter to select only residues you want and change bond settings and color for these, manually flip some parts of the residues. If you give me an e-mail address I can send you a printscreen

[@caatzy]

hi, how do you calculate the pKa in chemdraw?

[@PierreMx3]

Hi, select molecule and go to View > Chemical Properties

[@caatzy]

yes, but this option only shows pKa from some refrences. Is there no option to find 'predicted or estimated' pKa?

[@faroukvilla567]

what about the IR spectre prediction ?? need help

[@PierreMx3]

IR prediction is not possible in ChemDraw

[@faroukvilla567]

ChemDrawWizard thank you sir 😍😍

You're welcome Sasha

[@waauu]

Thank you so much, it was very helpful!

[@ziomp]

Does anyone know hot to change subscript hotkey from F9 to different one?thanks

[@PierreMx3]

That one cannot be changed

[@ziomp]

thank you very much for your answer;) you make my life so easy with chemdraw:P

[@PierreMx3]

Very strange indeed, at least things are working now!

[@IMattHarding666]

disregard the last comment, i fiddled around and somehow got it to work!

[@blickrausch]

awesome.

[@dangerdackel]

Its Ziconotide.

[@yazdanmaghsoud6302]

You speak super fast and not tutoring well. I really cannot understand some of the things that you are explaining cause you don't explain which keys you are using
