Landlord: I'm also yours in this problem, but now it's solved! Select a random file first -- right-click to open it --- select the program! Then choose as shown in the picture! Restart the CAD after it is set up. ok problem solved!

Reason 1: There is a problem with the drawing itself.

Solution: The drawings need to be repaired at this point. Click the [File] menu - [Drawing Utility] - [Repair] - save the file and open it again. See image below

Cause 2: There are vulnerabilities in the CAD installation. In this case, it can be solved after reinstalling the CAD.

Type pickfirst in CAD, set the parameter to 1, and you're OK... Strong likes, top up...

It's okay, press Ctrl+V again.

There is no separate "Ctrl+" command in CAD, Ctrl needs to be used with other keys to achieve command input, the corresponding commands are as follows:

Ctrl+B: Grid snap mode control (F9).

CTRL+P : Print.

Ctrl+C: Copy the selected object to the clipboard Ctrl+F: Controls whether to implement automatic object snapping (F3) Ctrl+G: Grid display mode control (F7).

Ctrl+J: Repeat the previous command.

Ctrl+K: Hyperlink.

Ctrl+N: New drawing file.

Ctrl+M: Opens the Options dialog box.

Ctrl+L : Turns on orthographic mode.

Ctrl+0: Full screen.

This is the command used by Tianzheng, ctrl+ is to open the drawing bar to the left of Tianzheng.

CAD itself does not have this shortcut key, it is a shortcut key used by Tianzheng Construction and Haochen Construction to open the side menu.
