It is written in manual that after selecting bond I can change it's length in "Structures -> Measure -> Set bond length", but I could see only "display bond length" option. What am I doing wrong?

The same question about bond angle - how could I change it?

In fact I want to rotate one cycle (in naphthalene) about C-C bound between cycles and calculate bond energies in new configuration. But I did not find tool to make it.. So I need to move atoms manually but bond lengths are not fixed (while I do not want to change them, only angles).

Thanks in advance for any help.

I managed to change bond length by printing new value in table with actual length, but for angle in cycle it does not work.

When you click on Structure > Measurements > Generate All Bond Angles a table is displayed on the left side.

This table allows you to display each angle individually. Additionally, you can edit manually the Actual value of each angle in order to make the change.

Hope this helps.

You may need to reinstall the software. If that doesn't work please submit a ticket to our support team here:

It will not help anyway. Draw naphthalene and try to change angle C(7)-C(1)-C(6) - you will not able to. I meaned exactly this.
