To start creating 3D models in AutoCAD, there are hardware and software requirements that we must meet.

The general hardware requirements are the same as those discussed in Chapter 1, An Introduction to AutoCAD. They may vary to according to the version used and the model size, and the recommended requirements for AutoCAD 2021 can be found at https: //autode.sk/2CTGy2d.

In terms of software requirements, access to the 3D modeling functionality requires the full version of AutoCAD, as most of the 3D modeling commands and tools are not present in the LT version. In AutoCAD LT, you can only open 3D model files built using the full version and do some small modifications, but it is not possible to create a full model.
