This article is intended for users who need to centrally organize engineering drawings, design files, and project documents, introducing how to use HeSoft Doc Batch Tool to batch convert multiple CAD files to PDF format. Whether the files are DWG, DXF, or DWF, they can be processed centrally by adding files or importing from folders, reducing the repetitive tasks of opening and exporting one by one, and improving the efficiency of drawing archiving, circulation, and delivery.
In engineering design, construction management, manufacturing and processing, decoration detailing, and project archiving, CAD drawings are often saved in formats such as DWG, DXF, and DWF. The problem is that these formats usually require specialized software for stable viewing. When sending them to clients, owners, procurement, administrative, or archival staff, they often need to be converted to PDF. If a project contains dozens or even hundreds of drawings, opening each CAD file individually, selecting print or export to PDF is not only time-consuming but also prone to omissions and incorrect conversions, and maintaining consistent file naming is also challenging.
This article addresses the issue of "batch converting many CAD files to PDF format." We will use screenshots to demonstrate the "CAD to PDF" function in the office software " HeSoft Doc Batch Tool ", which adds DWG, DXF, and DWF drawings from the same folder into a task list and outputs them as PDF files in batch. Its core value lies in batch processing files, helping users reduce repetitive work and centralize the drawing conversion process that originally required repeated operations.
Applicable Scenarios: When do you need to batch convert CAD drawings to PDF?
If you frequently handle drawing files, batch CAD to PDF conversion will be very practical. For example, a design institute needs to organize a set of construction drawings into PDF for client review; an engineering project department needs to archive site change drawings, floor plans, layout plans, and other documents; a manufacturing enterprise needs to convert part drawings and assembly drawings to PDF for distribution to production, procurement, or suppliers; a decoration company needs to send DWG drawings as PDFs to customers for confirmation; and archival staff need to convert DXF and DWF files from historical projects into a PDF format that is easy to view and long-term preservation.
The advantage of PDF lies in its strong compatibility, ease of circulation, printing, and archiving. Compared to CAD source files like DWG, DXF, and DWF, PDF does not depend on a specific CAD editing environment, and recipients can usually open and view it directly. Therefore, batch converting a large number of CAD files to PDF is a very common office processing requirement in drawing delivery and document management.
Result Preview: Multiple CAD formats before processing, unified as PDF after processing
Before processing: The folder contains DXF, DWG, DWF, and other CAD files
From the screenshot before processing, it can be seen that the files to be converted are not a single format but include SiteA.dxf, Roof.dxf, Plan1.dwg, Map1.dwg, Layout.dwg, Floor1.dwg, Model.dwf, Draft.dwf, Build.dwf, and others. This is a typical batch of CAD drawing data, with extensions including DXF, DWG, and DWF.

If processing these files manually, one would typically need to open different drawings individually and then export them to PDF one by one. The more files there are, the more apparent the repetitive operation becomes, and the easier it is to have omissions. Using a batch processing tool allows these files to be imported into the task list at once for centralized conversion.
After processing: Each CAD file generates a corresponding PDF file
The screenshot after processing shows that the original Build.dwf, Draft.dwf, Floor1.dwg, Layout.dwg, Map1.dwg, Model.dwf, Plan1.dwg, Roof.dxf, and SiteA.dxf have been converted into corresponding PDF files, such as Build.pdf, Draft.pdf, Floor1.pdf, Layout.pdf, Map1.pdf, Model.pdf, Plan1.pdf, Roof.pdf, and SiteA.pdf. The main body of the filenames maintains a corresponding relationship, facilitating subsequent verification and archiving.

This type of output result is suitable for direct sending, printing, system uploading, or inclusion in project data packages. For drawing data requiring a unified delivery format, batch conversion to PDF can significantly reduce manual sorting time.
Operation Steps: Using HeSoft Doc Batch Tool to batch convert CAD to PDF
Step 1: Go to "More Tools" and select "CAD to PDF"
After opening HeSoft Doc Batch Tool , in the left function navigation, you can see categories like Home, Task Flow, All Tools, File Name, Folder Name, File Sorting, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, and More Tools. According to the screenshot, this function is located on the "More Tools" page.
On the More Tools page, find the "CAD to PDF" function card. The description for this function is "Batch convert CAD format to PDF format," which perfectly matches the goal of this article. Clicking this function card will enter the batch processing interface for CAD to PDF conversion.

The purpose of this step is to confirm that the correct function type is being used. Since the same page also includes functions like "CAD to DWG," "CAD to DXF," and "CAD to DWF," if the goal is to output PDF, you should select "CAD to PDF" to avoid entering other format conversion processes.
Step 2: Add the CAD files to be converted
After entering the "CAD to PDF" interface, you can see the "Add Files" and "Import Files from Folder" buttons at the top. If only a few specific drawings need to be converted, you can click "Add Files" to select them individually; if the drawings are stored collectively in a certain folder, it is more suitable to click "Import Files from Folder" to import the CAD files from the folder into the task list all at once.
The screenshot shows 9 records have been imported. The list displays information such as sequence number, name, path, extension, creation time, modification time, and actions. The imported files include Build.dwf, Draft.dwf, Floor1.dwg, Layout.dwg, Map1.dwg, Model.dwf, Plan1.dwg, Roof.dxf, and SiteA.dxf, with extensions covering the three CAD formats dwf, dwg, and dxf.

The purpose of this step is to put all the CAD files that need processing into the same batch task. After importing, it is recommended to check the number and names of the files to confirm that the records in the list match the actual drawings to be converted. The bottom of the screenshot shows "Record count: 9," which helps users verify if any files were missed. If incorrectly added files are found, they can be removed using the delete icon in the "Actions" column on the right side of the list; if reselection is needed, the "Clear" button at the top can be used to clear the current list before importing again.
Step 3: After confirming the records, click "Next"
Once the file list is confirmed to be correct, click the "Next" button at the bottom of the interface. From the process prompt at the top of the interface, the entire processing flow is divided into three stages: "Select records to process," "Set save location," and "Start processing." The current screenshot is at step 1, and clicking next will proceed to setting the save location.
The purpose of this step is to finalize the file selection stage and enter the output settings stage. For batch conversion tasks, checking the input files first is crucial, as the subsequent PDFs will be generated in batch based on these records. If a certain DWG or DXF file is missed here, it will naturally not produce a corresponding PDF after processing.
Step 4: Set the PDF save location
Entering step 2 requires setting the save location for the converted PDF files. Although the screenshot does not expand the details of this page, the process bar clearly shows "Set save location," indicating that the software will ask the user to determine the output location before starting processing. It is recommended to choose an easily identifiable folder, such as the project name plus "PDF drawings," making it easier to find, package, and send after conversion.
When setting the save location, it is advisable not to mix them with the original CAD files, especially when there are many drawings. Placing the output PDFs in a centralized, independent folder can avoid mixing source files and result files during later verification. For projects requiring archiving, directories can also be created by project number, date, or professional category.
Step 5: Start processing and check the PDF results
After setting the save location, enter step 3, "Start processing." After initiating the task, the software will batch execute CAD to PDF conversion according to the list records. Once complete, open the output folder and check if PDF files corresponding to the source files have been generated. According to the screenshot after processing, all 9 CAD files have been output as PDFs, with filenames corresponding to the main body names of the source files, making it easy to quickly confirm the conversion results.
The expected result of this step is to obtain a batch of PDF drawings that can be viewed, sent, and archived. Compared to manual individual processing, the advantage of batch conversion lies in a more centralized process and fewer operations, especially suitable for complete sets of drawing data.
Common Issues and Precautions
1. Can DWG, DXF, and DWF be imported together?
From the task list in the screenshot, it can be seen that dwg, dxf, and dwf files appear simultaneously in the same "CAD to PDF" task and are included in the pending records. Therefore, in this example, multiple CAD extensions can be imported centrally and converted to PDF. During actual operation, it is recommended to import a batch of files first and check the extension column to confirm that all drawings requiring processing are in the list.
2. How to avoid missing file conversions?
It is recommended to use "Import Files from Folder" to process centrally stored drawings and check the record count at the bottom of the list after importing. For instance, the record count in the example is 9, and 9 PDF files were generated after processing. For situations with a large amount of project data, you can organize the source folder first, then perform a batch import.
3. Will the filenames be difficult to match?
Judging from the post-processing results, the PDF filenames maintain correspondence with the main body of the original CAD filenames, for example, Build.dwf becomes Build.pdf after conversion, and Plan1.dwg becomes Plan1.pdf. This naming convention facilitates verification and delivery, and also aids in subsequent viewing by sorting names in the folder.
4. What precautions are needed before conversion?
It is recommended to first confirm that the source CAD files are accessible normally and that paths are not moved frequently; if drawings come from a compressed package, they should be extracted to a local folder first; if the file count is large, it is advisable to categorize them by project or profession first, to avoid importing unrelated files into the same batch task. After conversion is complete, spot-check a few PDF files to confirm the output results meet delivery requirements.
Summary: Reducing repetitive work in CAD to PDF conversion with batch processing
Batch converting CAD files to PDF essentially solves the problem of repetitive operations in drawing delivery and data archiving. Using HeSoft Doc Batch Tool , you can use the "CAD to PDF" function to centrally add DWG, DXF, DWF, and other drawing files to a list, uniformly set the save location, and then generate PDFs in batch.
If you are organizing a set of engineering drawings, design drawings, or project archive files, you no longer need to open each CAD file individually for manual export. It is recommended to first place the drawings to be converted into the same folder, then use "Import Files from Folder" for batch addition, verify the record count, and proceed according to the workflow. This way, you can quickly obtain clearly structured, correspondingly named PDF results, making drawing circulation, printing, and archiving more efficient.
