Please, post comments here!
Thanks for making this app! Any chance that the ability to generate the name of a molecule could be added in the future? I’m a high school teacher and am using this to help make worksheets and practice problems in organic chemistry.
Not that I can’t generate the names myself, it just saves time.
Thanks for your great feedback. I am a chemistry teacher too and it’s good to hear that my program seems to be useful. I have already thought about a name generator, but it’s not on top of my list of new features for MoleculeSketch. Mostly because I think, that it’s not an easy task to program. Anyway, I will keep it on the wish list. Just let me know, if you have other suggestions.
Hi Stefan, just bought your program and I really like it.
My needs are simple – get structures, formulas and reactions into an article, and your app delivers.
I have one wish though, the ability to export the selection to png, jpg.
Keep up the good work!
Thank you for the positiv feedback! I will take the possibility to directly export to png/jpg on the wish list for future improvements. In the mean time it is not too complicated to get a png or jpg of a MoleculeSketch structure. Just copy the structure and paste it in the standard macOS Preview App (in Preview App choose Edit in the menu bar an copy from pasteboard). You can then do whatever you like.
Structure can also be pasted in any other (office) programs that support pdfs. This has the advantage, that you can scale the structure without loosing quality.
Thank you Stefan, good tips there.
I’m having a very, very hard time figuring out how to use this program unfortunately! Like, if I want to create N2, how do I do that? Is there a shortcut way to add elements other than selecting them with the mouse up in the toolbar? Do you have videos explaining how to use molecule sketch? I have been through the support documentation, and haven’t had much luck learning how to use the program :/ It looks like the functionality is great though and I really want to learn to use it!
I am sorry, that the use of MoleculeSketch is not as intuitive as it should be. I am developing this app on my own and do not have a lot of time in my spare time to work on tutorials and how-tos. At the moment all my effort is focused on developing an iPad version of MoleculeSketch, which will hopefully be finished soon…
To answer your troubles:
– to draw a N2 just choose the nitrogen atom in the toolbar and click in the drawing area. Then double click on the atom symbol. You can edit the symbol now. Just click after the “N” and type a “2”. When you click somewhere else in the drawing area you should get N2 (with correct subscript).
– any atom in your structures can be edited by double clicking. You can even type complex functional groups using special formating commands, that are described in the second chapter of help under “editing atoms, adding functional groups”. If you want to add greek letters, just type the characters in latin letters, mark them and right click over the selected text. You will find an option “convert to greek characters” in context menu.
I hope this will help you. If you have more questions, just ask.
Hi Stefan I downloaded your programme and it is really quite useful, but is there a possibility to convert the msf file into another one for example xcd?
Unfortunately it is not possible to convert the msf files into other formats. But I will put it onto the to-do list!
Sorry for the inconvenience.
Hi Stefan, I too find this to be an excellent program. I have a collaborator who uses Chemdraw. Is there anyway to read these files with Chemdraw and vice versa.
Thank you for your positive feedback. Import and export capabilities of MoleculeSketch are unfortunately a bit restricted. You can import files in the MDL mol format (V2000). Chemdraw may be able to export to this file format. MoleculeSketch on the other hand has no export function (yet).
I think this is a great app but I still have some problems trying to figure out some minor details.
In the pictures you see in the App Store, there apear equations with subscripts and superscripts.
How do I insert them in the textbars?
Also, it would be nice to have a little more liberty with changing colors.
Apart from that, I think it’s all good.
Thank you for your time,
To insert sub- or superscripts in textboxes, just choose the text button (“abc”) in the menubar and click in a textbox or double click in a textbox with the selection tool (crossed arrows), then select the text you want to format and right-click on the selection to reveal the context menu. From there you can choose different format styles or change the font of the selected text.
Element labels can also be formatted. Just double click on an atom label and type into the appearing textbox. There are special markup commands that can be used to format the label. You can find more information about this in the Help section “Editing atoms, adding functional groups”. I hope to find some time soon to develop a more intuitive UI implementation for the label formatting.
Hi, I’m having big problems with the new version on my mac. When I paste from one file to another the pasted items only partially appear and then when I try to save I get amessage that the model configuration used to open the store is incompatible with the one used to create the store. I cannot then save the documents.
I am sorry to read, that you have some problems with the new version of MoleculeSketch.
I tried to repeat the copy/paste problems that you described in your message. Unfortunately I was not able to reproduce the same errors you found.
From what you wrote, it seems that there is some mismatch with the new and old program version. When you open a file that has been saved with MoleculeSketch prior to version 2.0 you should get a message, that the file has been converted. If not please check, if the file has really been opened in the new program version. You can check this by clicking on MoleculeSketch in the menu bar next to the Apple Logo and then choosing „About MoleculeSketch“. In the appearing Window the current version number 2.0 (43) should be displayed. If not, it seems as if the program has not been updated or as if the old version of MoleculeSketch is still present. In this case try to locate and delete the program in your Applications folder or redownload it from the AppStore.
If this does not help, could you please send me more information about how the error occurs or even a file that produces these problems.
This is a wonderful app! I am only having one problem: When I go to export the backbone of my molecule disappears. Are there ways to circumvent this?
Thank you for the positive feedback.
The problem that you have when exporting, seems to be a bug. I tried to reproduce the bug, but was not able to do so.
Do you have more information when or how exactly this is happening? To which file format are you exporting? Do you use the latest app version (on macOS 2.0 and on iOS 1.0.1)? Do you use the mac or iPad version of the moleculeSketch?
Hopefully I will be able to solve this export bug soon.
