If you mean AoutCAD, it is estimated that you have a certain foundation of graphic drawing, but if you want to further learn the three-dimensional design of AoutCAD, then I suggest you learn Rhino software! After all, AoutCAD is not a 3D software, but Rhino is a powerful 3D software. Its two-dimensional drawing is very similar to AoutCAD, and it has the foundation of AoutCAD. Learning Rhino has made great progress, and that's how I got here. In addition, Rhino provides a special file format for AoutCAD, which can be used interchangeably.

If you mean JewelCAD, I still suggest you learn Rhino, because JewelCAD only makes jewelry design, and this software is not suitable for other industries. Rhino can specialize not only in jewelry design, but also in other industries, because it is equipped with professional plug-ins in many industries, as well as rendering plug-ins and animation plug-ins, and it is a very promising software.

All right! Having said so much, I hope I can help you! I wish you all your wishes!
