CAD should first be familiar with shortcut keys. I suggest you search for some shortcut keys and download some related exercises on Baidu after installing CAD. Generally, if you do more shortcuts, you will be familiar with them, and CAD is almost the same.

You can try!

AutoCAD (CAD for short)? It is not difficult to learn and become a CAD expert. The only way is to be diligent.

The current CAD software is version 2007, which has greatly changed the construction of 3D model and the operation mode of built-in renderer. It is recommended to study the 2004~2006 edition.

The main operation mode of CAD master is keyboard command (you can edit the shortcut key mode yourself).

1.CAD includes drawing, editing (including modification), system operation, rendering and LISP programming (advanced operation part). I suggest you learn drawing and editing (including revision) well first. The contents of these two parts can be interactive.

2. In terms of operation modes, it includes mouse operation, keyboard command operation and sketchpad operation. It is suggested that you can start with mouse operation (you can't input some secondary commands and data without keyboard, etc.). ) and familiar with some keyboard commands with the same function.

3. From the drawing and editing forms of objects, it includes two-dimensional objects and three-dimensional objects. Learn two dimensions first. The three-dimensional part is divided into solid and surface, which can be interacted.

After entering the door, you can do the following:

1. How to output. The categories of product output include engineering drawing (2D) output, model (mainly 3D) and effect drawing output.

Specific output operations include printout and model format conversion (delivered to 3D modeling, animation and rendering software such as 3DSMAX and Lightscape). ) and other format conversions (editable text such as DXF).

2. Collect and edit some commonly used models and modules according to your own professional content, and establish your own library.
