Thank you for your interest
GstarCAD is available as a "perpetually licensed" product. You own the perpetual right to use the purchased license. It is more convenient than ACAD subscriptions.
Multiple Licensing Modes
GstarCAD Licensing Mode is available with both Serial Number and USB Dongle, each could be used for Stand-alone or Network license. You could choose either one based on your business needs.
Flexible Access to Upgrade
You can upgrade your license for every new version or keep using the same version. When you upgrade your license it keeps perpetual license unchanged.
