Sketch a structure and Send to 3D to build it in the main viewer, or pull whatever is already in the 3D viewer back into this editor with ← Get from 3D (it also loads automatically when you open this panel). New to structural formulae? Show all atoms labels every carbon and hydrogen, rather than the chemist's shorthand where a carbon is assumed at each corner. Need the picture rather than the model? Copy image puts a PNG on your clipboard — Ketcher’s own copy gives structure data, which Word cannot show. Tip: add explicit hydrogens for a fuller model.
