For our further exploration of the TS software functioning, we have to
examine the snapping tools. The snapping tools aim to facilitate choosing
the right geometry types for the physical snapping of the objects during
any structure modeling. Thus snapping indicates the points' or objects'
position at the geometry. There are several snapping tools. You can read
their descriptions by pointing the mouse cursor to any snapping tool icon.
Familiarize yourself with all of them.
Activate all the snapping tools, except for “Snap to lines and edges”.
