C # Call the AutoCAD component to convert DWG to PDF

The following is a demo (I am currently in HIGER, so the copyright is it, huh, huh). The principle is to print DWG to a printer. To enable automatic printer, you must support automatic saving, the following parameter creator is supported.

If you want to debug it, just create a project and add a FORM ~~~~~~~~~~~
