CAD Error What should I do if the entered list is defective and I don t want to reinstall it?

Regenerate once and try again.

This is due to infection with a CAD file virus.

<>6. Click [Start] to automatically scan the virus files on the computer, and the scanned files will be automatically removed.

1. Select "File - Drawing Utilities - Check" in the menu bar; You can also type "audit" on the command line and press enter.

3. Next, in the pop-up dialog box, select the CAD file you want to repair and OK.

4. Then the repair process will automatically pop up, if the repair is completed, the drawing can be displayed normally.

5. Finally, select "Tools - Options - Open and Save" in the menu bar and it is done.

AutoCAD has AutoLisp function interface, which can load AutoLisp programs to improve drawing efficiency. Due to the frequent use of autolisp, it is generally set to autoload. If the program is defective, if there is one missing arc, then when opening AutoCAD, the command line will prompt "the input list is defective" or "the input contains extra closing brackets", etc.

Slow response should be your computer's problem, the configuration and processor are too low, and this is generally best done with a desktop computer.

That flaw of yours doesn't seem like I've encountered it either, I'm sorry for this.

It seems to be a CAD virus, find a CAD virus killing tool, and give it a try. After using 360, it can be solved.

The first one is to reinstall the software and see if it is corrupted; Or see if your current version is compatible with your software. Hope it helps!

It should be said that these are two errors, and they are caused by two error sources.

The first error, which is the prompt";

Error: The input list is defective", its source is deeper, it may be an internal ACAD error, the reason is also more obscure, it may be a problem with the password lock, or it may be other program errors. Generally, there is no good solution, so you can only try it again.

The second error, which is the prompt "Error:

Parameter type is incorrect:

stringp

nil", it is an external error and is caused by an external application.

and is caused by a program that is loaded and executed. Specifically, a program statement asks for a string of parameters, but the type of data provided is not, causing an error. This error is most likely to be caused internally, and there is a high probability of bad faith.

Typical programs are only loaded on the CAD command line.

It is executed when the window gives a command, and the program is automatically executed as soon as it is loaded. For ACAD 2004, this program has been deprecated and the Windows search function is available.

Find it and delete it. Generally speaking, errors in external programs do not affect the functionality of the CAD, and can be ignored if they are not malicious.

Or you didn't follow the prompts step by step during the installation process. Let's do it all over again, oh hahahahaha

Is your CAD file converted from another software, or is it inserted from somewhere else, if so, that's normal.

Can you send a ** to see, the description is not quite clear.
