Creating a Template
Select the appropriate template from the Template toolbar, then left-click on the canvas, where you would like to put the structure. The template appears on the canvas.
Appending a Template to Another Structure
Select the appropriate template from the Template toolbar, then push the left mouse button and drag it on the canvas. A gray structure will appear to show the position of the dragged template.
When the dragged substructure element gets so close to the other molecule fragment, a purple highlight appears on the atoms concerned. If the left mouse button is released now, the two fragments are automatically merged.
You can append a template to another structure by selecting the required template tool, then clicking over the bond ...
It is also possible to append a template to another structure by electing the required template tool, then clicking over the appropriate atom.
When clicking on an atom with the selected template, the template automatically sprouts from that atom (the template will be connected to the atom with a bond). You can position the template by dragging the cursor before releasing the left mouse button.
To rotate the template around one bond on creation, follow the steps below:
Select the template.
Press the left-mouse button over the object (atom/bond) you would like to add the template to.
Press the Shift button (as many times as necessary) before releasing the left mouse button.
Once you put the template onto the canvas it can be deleted as other structures.
