I don't have Autocad software and I can only find this free tool which can't read .dwg files.

Now, I need to convert .dwg to .pdf. But the teigha true view can't export .dwg

to .pdf. But I find it offers a plot command. Unfortunately, I aslo don't have the

DWF6 ePlot.pc3 printer. So, does anyone know how to handle that or is that an impossible

task? Do you know any other software can convert .dwg to .pdf?

  • what is your AutoCAD version?

I haven't tried any of these, but a simple Google search yielded these:

That last one looks like you need to upload the file to their server which may have issues if the file is big. It may have privacy implications.

  • Thanks for your reply. But I need a free solution and better run in command line or embeded my application. I have consider your search result. they all need to pay money and may not support all .dwg version. I think teigha tools is the best solution

Autodesk DWG TrueView is a a free stand-alone .dwg viewer with DWG TrueConvert software included. It includes PDF plotters so you can directly plot to pdf. This would be the most reliable option.

you can download from Autodesk Website

There is a Plot/Batch Plot option too

  • Great, That is what I need. Another question. How can I call Autodesk DWG TrueView in java to plot.

IrfanView is free and has a variety of plugins. You can read a DWG and write to PDF. Also, IrfanView has a commandline interface. If this doesn't open the latest DWG version, you can convert your DWG to an older version using Teigha File Converter. I think this has a command line option, as well.


You can also upload your dwg to https://www.autocadws.com en convert it from there (use the "download" button). You can definitely upload to autocadws using webdav, not sure if the conversion can be applied from the api. Have a look at: http://www.autocadws.com/tutorials/autocad-ws-apis-c-client/

One advantage is that autocad ws can handle whatever dwg format out there, so your application will still support dwgs made in 2015, when the format will probably change again.

or with more online converter https://cloudconvert.com helps convert dwgtopdf document
