GstarCAD – DWG compatible CAD

The best AutoCAD® alternative


AutoCAD® DWG format

No data conversions, imports or exports. In GstarCAD you work with drawings directly in DWG format, which is fully compatible with CAD users from various industries around the world.

Familiar user interface

GstarCAD is designed to be as similar to AutoCAD as possible so that the user would not notice the differences between the two programs.

The goal is to significantly reduce the time and money that would otherwise be required to retrain when switching to new software.

Permanent license at a low price

When you purchase you get a lifetime license. That means, you can use the program indefinitely in a certain version. Future updates are available in the form of one-time upgrades or even cheaper with the Subscription AutoRenewal 365 subscription service.

GstarCAD Standard offers extensive functions for universal 2D technical drawing. It enables technical drawings to be created according to international and national standards or your own standards. In contrast to AutoCAD LT, GstarCAD Standard also enables expansion modules and industry modules to be used.


GstarCAD Professional contains everything that the 2D standard version does. In addition, it offers functions such as dynamic blocks or a magnifying glass. However, it differs the most in 3D. Modeling solid bodies, importing and exporting models from other 3D software enable drawings to be completed more quickly. Of course there is also STL export for 3D printing.
