Convert DWG to PDF in Python

DWG file stores 2D and 3D design data such as geometric data, color, materials, and text. It is a proprietary file format of AutoCAD, a computer-aided design (CAD) software application. Since DWG files are quite large, they are often converted to other file formats, like PDF, for easier sharing and collaboration. PDFs are a popular choice for this purpose, as they can be easily viewed and shared across different platforms. But, converting DWG files to PDFs can be a tedious task, especially if you have a large number of files to convert. In this blog post, we will learn how to convert DWG to PDF in Python. So, let’s get started!

How to Convert DWG File to PDF

We can easily convert a DWG file to a PDF document by following the steps given below:

  1. Load a DWG drawing file.
  2. Specify CAD rasterization image options.
  3. Define PDF save options.
  4. Save DWG as PDF.

Now, let’s see how to perform these steps in Python to convert a DWG file to a PDF document.

Convert DWG to PDF in Python

Please follow the steps given below to convert a DWG to a PDF:

  1. Load an input DGN file using the Image class.
  2. Create an instance of the PdfOptions class.
  3. Finally, call the save() method to save DWG as PDF. It takes the output PDF file path and PdfOptions as arguments.

The following code sample shows how to convert a DWG file to a PDF document using Python.

Export DWG to PDF with Options in Python

We can specify PDF save options while converting a DWG file to a PDF document by following the steps given below:

  1. Firstly, load an input DWG file using the Image class.
  2. Next, create an instance of the CadRasterizationOptions class.
  3. Then, specify the page_width and page_height properties.
  4. Meanwhile, create an instance of the PdfOptions class.
  5. After that, set the vector_rasterization_options property as CadRasterizationOptions.
  6. Finally, call the save() method to save DWG as PDF.

The following code sample shows how to specify the page height and width while saving a DWG file as a PDF document using Python.

Export Specific Layout of DWG to PDF in Python

We can specify PDF save options while converting a DWG file to a PDF document by following the steps given below:

  1. Firstly, load an input DWG file using the Image class.
  2. Next, create an instance of the CadRasterizationOptions class.
  3. Then, set the Layouts property.
  4. Meanwhile, create an instance of the PdfOptions class.
  5. After that, set the vector_rasterization_options property as CadRasterizationOptions.
  6. Finally, call the save() method to save DWG as PDF.

The following code sample shows how to specify the specific layout of a DWG file to export as a PDF document in Python.

Convert DWG to PDF/A or PDF/B

We can also save DWG as PDF/A or PDF/E by following the steps given below:

  1. Firstly, load an input DWG file using the Image class.
  2. Next, create an instance of the CadRasterizationOptions class.
  3. Then, create an instance of the PdfOptions class.
  4. After that, set the compliance property.
  5. Finally, call the save() method to save DWG as PDF.

The following code sample shows how to convert a DWG file to PDF/A and PDF/B using Python.
