What is DWL in CAD? What is it used for?

DWL is a locked CAD drawing file (where L=LOCK), which is easy to automatically generate the same name as the DWG file name but with an extension when CAD is illegally exited.

Locked files for dwl. Once this file is generated, your DWG file will not open and you will have to manually delete it before you can resume opening the DWG file. In fact, this file doesn't have much effect.,The main thing is that in the shared file, if you see the dwl file, it means that the dwg file has been opened by someone else.。。

After the file is closed normally, the dwl file will be automatically deleted.

A DWL (Graphics Lock) file is a format associated with a DWG file, where the "L" in DWL stands for "Lock". The file attributes of the dwl are hidden.

1. When opening the dwg file, the lock file dwl will be created in the directory, indicating that the document has been opened, and the corresponding dwl will be automatically deleted when the dwg file is closed.

2. When the file is closed abnormally, the dwl file will not be automatically deleted, and when the dwg file is opened again, it will prompt that the file has been opened by a computer, and the corresponding dwlDeletion does not affect the DWG file.

3. You can use the [whohas] command to track which users open a drawing file. The information that can be queried includes the current user's computer name, login ID, the user's full name (if any), and the date and time the drawing file was opened, and the displayed information is stored in a temporary DWL file.

In the process of drawing the earth pool with Haochen CAD software, when the DWG format file is opened, the system will automatically generate a file of type DWL, and when the user closes the drawing, this DWL file is gone.

Haochen CAD system,DWL (that is, the meaning of graphic locking) file is a format related to DWG files,Here the "L" in DWL means "lock" locking. Generally speaking, the file properties of the DWL are set to hidden by default.

When a user opens a dwg file, the system will create a lock file dwl in this directory, indicating that the file has been opened and used by the user, preventing other programs or users from modifying it. When the user closes the dwg file, the system will automatically delete the dwg file.

But in one case, when the file is closed abnormally, then the DWL file will not be automatically deleted by the system by default, when the user opens the DWG file again, the system will prompt the user that the file has been opened by a computer, then the corresponding DWL file will no longer affect the DWG file.

1. Open the CAD software installed on the computer.

2. On the menu bar, find "Tools".

3. Click on the option under "Tools".

4. Choose to be cautious about "Open and Save", in the "File Security Measures Wheel", the second is "Create a backup every time you save", which is what you are talking about".bak"File.

5. Remove the checkmark before "Create a backup every time you save" and click "OK".

As long as you install the AutoCAD software on your computer, after opening the software, you can drag your DWG file into the interface of the CAD software with the mouse, and you can open it. You can also click on the "Key Base File" in the upper left corner and "Open" and then click on the dwg file in your computer (you need to remember the path of your dwg file), or you can directly click on your dwg file with the mouse, and you can also open it. Pay attention to the version of your software that is higher than the version of your DWG file.

So when saving, try to save it in a lower version format. In order to ensure that it can be easily opened in all versions of the CAD software.

You can double-click the file to open it, or open the CAD software and select the file to open it, provided that the version of the DWG file must be lower than the software version you are using, otherwise it will not be opened.

This temporary file will appear when you open a DWG file with AutoCAD, and it will disappear when you close the CAD. If there is, you can delete it directly, it is useless.

This is a file that CAD automatically generates after you open a drawing, and it will automatically disappear after closing the drawing, and will remain there unless it is closed illegally.

See below for details:

In AutoCAD R13 and earlier, when opening a drawing, a DWL file is generated in that directory indicating that the drawing has been opened and should be locked. Since AutoCAD R14, this locking step is done by the system, and it stands to reason that the DWL file is not needed.

However, in some later versions, a utility called user tracking (whohas) was used to determine who had opened the graphic file. This program will generate a dwl file. Of course, when we uninstall the program, the dwl file will not be generated.

But once we use whohas, the program will be automatically loaded, unless you delete it from the AutoCAD directory.

Actually, AutoCAD 2002 also has whohas, but it doesn't load automatically when you start AutoCAD. When you use it, it will still load, and at this point, a dwl file will also be generated. For AutoCAD 2004, whohas is automatically loaded at startup.

Delete. DWL files have no effect on drawings.

Electronic plates.

Caxa: This is the easiest.

Caxa is definitely no problem to open.

For the general situation, the way to open DWG files is practical CAD software, but not all people will install CAD software on their computers, on the contrary, there are many people who are in contact with CAD files for the first time, what should I do?

Practical CAD drawing software can also quickly help us view CAD drawing files, if you want to open it simply and quickly, try fast CAD drawing, simple operation, quickly open DWG files, and can also be simple CAD files, which helps solve a lot of problems in daily work.

2.After entering the CAD viewing interface, click the "Open File" button to open the DWG format file that needs to be viewed.

DWG drawings can be opened with CAD mini viewers. The software is very small, only a dozen megabytes, the opening of drawings is very fast, and the conversion of Tianzheng drawings is free.

1. Open the CAD software installed on the computer.

2. On the menu bar, find "Tools".

3. Click on the option under "Tools".

4. Select "Open and Save", in "File Security Measures", the second one is "Create a backup every time you save", which is what it says".bak"File.

5. Remove the checkmark before "Create a backup every time you save" and click "OK".

1. Open the tool and select [Options].

2. Click [Open & Save] and select [Security Options];

Open Tools-Options There is an open and save file security measure in the lower left corner, just remove the tick inside and save it.

This should be the CAD backup file, open the tool window and uncheck the automatic backup file.
