This paper reports on solving geometric constraint
satisfaction problems involving incidence and tangency constraints
in 2D. A variational geometric constraint solver based on a
constructive approach is used: the main goal is to keep the present
set of rules as small as possible. Defining tangency conditions as
distance and angle constraints allows solving fixed radius
configurations. Non-fixed radius schemes are also characterized and
a new set of constructive rules is proposed.
