Hello, I come from China.
ChengtaMixDesign is an extension plugin based on CIVIL 3D developed by a Chinese engineer (who previously served as the customer manager for Autodesk C3D in China). It enhances the design functionality of C3D, making its planar and vertical geometry design functions very powerful, greatly simplifying the C3D operation steps and improving work efficiency.
Highly recommended for engineers who use CIVL 3D for road design, as it can greatly improve work efficiency and reduce the occurrence of errors.
I really hope your team can crack this plugin.
Thank you very much for your efforts, thank you again!
