AutoCAD requires activation and licensing to function properly. The software uses a proprietary licensing system that verifies the authenticity of the software and ensures that it is being used in compliance with Autodesk's terms and conditions.
If you're looking for a reliable and efficient way to access AutoCAD, consider purchasing a legitimate license or exploring alternative options. Remember, investing in official software ensures you receive the support, updates, and security you need to create high-quality designs and models.
