Any simple way to convert dwg to pdf without autocad on PC?

QCAD is a solid, open-source option if you're looking for a way to convert DWG to PDF without Autocad on your Windows PC.

Two Main Ways to convert DWG to PDF:

QCAD offers two primary paths for this conversion, depending on whether you prefer a visual interface or are comfortable with the command line.

1. The GUI Method (Click and Export):

The most straightforward method is through the main application itself. There's a dedicated PDF export tool you can find under File > PDF Export… (or by using the shortcut X, D). This will open a print preview, where you can adjust your drawing scale, page size, and position before finalizing the export. This approach is essentially identical to printing the file.

2. The Command Line Method (For Automation):

If you need to convert multiple files quickly or prefer automation, QCAD includes a command-line tool called dwg2pdf. This is very powerful for batch processing, as you can run commands like this in your terminal:

batch

dwg2 pdf -a -c -d -f -n -l -w 0.1 - fs romans standard -o output. pdf input. dwg

You can also use it in a loop to convert entire folders of files at once.

One subtlety I noticed is a known issue regarding line types like "dash dot" when converting to PDF. Some users have reported that dashed lines in the original DWG file appear as continuous lines in the generated PDF.
