1. Enter "skpoly" and "sketch" in the Command line, and then enter a new value, such as "1", to switch between tools and freehand drawing.

2. Enter "mirrtext" in the "Command" line, and then enter the new value "1", which can produce a real mirror image effect with opposite left and right.

3. You can change the drawing key method in CAD Installer-Support -pgp.

4. After inputting the shortcut keys "tr" and "ex", double-click the space bar twice to cut or extend the line at will in the drawing area.

Or press the space bar twice after entering the cut key "tr", and then press the left key of Shift to extend, as does the shortcut key "ex".

5.F7, F8, F3 and F 10 are the shortcut operations of grid, orthogonality, snap and polar axis respectively.

6.Z+ SPACEBAR +a is the shortcut key of "Real-time Zoom".

7. In the Image Attribute Manager, the frozen image part does not participate in the CAD operation, but the closed image content still participates in the operation. Therefore, when drawing three-dimensional or other large-scale drawings, in order to make the computer run faster, it is best to use "freeze" more.

In fact, you don't have to remember all of them, just remember what is commonly used and you can find what is not commonly used.
