Drawing the structure

To draw a structure with Ketcher:

• Click on the desired Drawing tool icon. The selected icon is highlighted.

• Click in the drawing pane to place or use the item.

• Repeat for all elements of the structure.

Connecting elements

For the elements to properly combine into a coherent structure, you need to carefully select the location for the new element.

• Place the first piece of the structure in the drawing pane.

• Select the drawing tool for the next item to insert into the drawing.

• Point at the exact location where the new element connects to the existing drawing. A visual indicator appears at the exact location on the existing structure where the new item will connect.

• Click.

Note: To select amongst a single, double, or triple bond, point to the middle of the bond to modify and click through the bond types until the desired one displays.

Deleting elements

To remove the last element inserted, click on the Undo icon.

Deleting the complete structure

If you are still in the drawing application and realise you do not want to keep the structure you were drawing, click the Clear button in the upper right corner.
