Tech Previews, also referred to as technical or technology previews, offer you the opportunity to access new features in AutoCAD before they're officially released. By participating in Tech Previews, you can explore and test out the functionality of these new features and provide valuable feedback to the AutoCAD product team.
During a Tech Preview, the preview features are fully functional and ready to be used. Since these features are still under development, additional capabilities and improvements may be available for testing. This provides you a chance to evaluate how these features can benefit your workflows and projects.
Unlike Beta programs, Tech Previews are open to everyone, allowing active participation and contribution to the ongoing improvement of the feature's capabilities. Your feedback is important in shaping the final version of the feature.
AutoCAD is dedicated to continuously improve and evolve the preview feature until it reaches a stage where it's ready to be released as a regular feature, thereby transitioning out of the Tech Preview phase.
