Designing a polymer

[Elsaid]

Dear all,
I want to build up a long polymer chain of 300 of the monomers ethylene glycol C2H6O2. I can design one molecule or two but might there be a command or tool to make the repeats.
Thanks.

Dear Elsaid,

we just released an update of the editors which makes it possible to use the current selection to build. This should make it easier to build any polymer you want by repeatedly adding larger and larger groups.

When using the Rectangle selection editor (the default editor, shortcut R), show the context menu (either by right-clicking in the viewport, right-clicking in the Document view, or clicking the green selection widget in the Document view). The third context menu action is Use selection to build:

Clicking this action automatically switches to the Add editor ands use the selection as a building fragment:

The Use selection to build action is also available in the context menu when the Add editor (shortcut A), Edit bonds editor (shortcut B) and Edit charges editor (shortcut C) are active. Here it is for example in the Add editor:
