ACD Labs: Chemsketch – free modelling software

It’s not really a video, but you can build molecular models and make them move around on the screen, so it just about qualifies. It takes a wee while to get used to, but is worth the effort.

Demo videos here. Manuals here.

DP Bio teachers can use it to satisfy the modeling software stipulation of the 4/PSOW form. Enjoy!

EDIT – there is a shareware ($24.95) gif to flv encoder available here. I haven’t found any free software that can convert gif animations to flv files, so if anyone can help out, please let us know.

I have put a simple Chemsketch tutorial on making and animating glycine (word 2007 doc and SMART Board notebook file) in the downloads box on the right of this blog.


The joys of Chemsketch are almost limitless. Here is proof: Mildly Surprised Surferezene

  1. Where do I find the word document for the Chemsketch tutorial on making and animating glycine? I can’t find it anywhere?

    • I’m sorry – this is a very old post. Since then I’ve moved schools, countries and computing platforms. If I do find the sheet, I’ll post it here, but glycine is the simplest possible amino acid.
