ZWCAD licenses do not expire
ZWCAD licenses are permanent and do not require recurrent payments to continue to use them.
If desired, Maintenance can be purchased together with the license for an approximate cost of 20% of the license cost. This is a recurrent payment on an annual basis and allows you to have the latest software updates.
If the Active Maintenance Service is not purchased, the license can be updated by purchasing an Update for a cost of approximately 30% of the value of the new license.
