Apart from using common automenu options described in the Edit 2D Constructs section, when editing circles, you can change their tangency parameters using the following additional options:

Allows you to select a node for the current circle to pass through. Activating the option via keyboard instantly selects a node nearest to the current position of the cursor. Upon activating the option via mouse, you have to make a click within the drawing window, which results in selecting a node nearest to the point of clicking.

Allows you to select a line or an another circle for the current circle to pass through. Activating the option via keyboard instantly selects a line of the corresponding type nearest to the current position of the cursor. Upon activating the option via mouse, you have to make a click within the drawing window, which results in selecting a line of the corresponding type nearest to the point of clicking.

If the current circle is tangent to some lines, activating this option switches between possible tangency confirations.

Selection of a tangency configuration performed via the previous option () may reset upon changes in linked element's configurations. You should set a relation with node in order to fully define the tangency configuration.   Activating the option via keyboard instantly selects a node nearest to the current position of the cursor. Upon activating the option via mouse, you have to make a click within the drawing window, which results in selecting a node nearest to the point of clicking. In result, a tangency configuration nearest to the selected node will always be applied for the circle.
