This article describes linearized .pdf files and how to create them with Teigha.

Teigha’s PDF Export functionality now supports accurate measurements of CAD data in exported .pdf files. Let’s look at how it can be used and how it looks in a .pdf file.

There is often a misunderstanding between general plot settings and specific settings for exporting drawings to .pdf files. This can lead to a misunderstanding of how to implement a feature for exporting a drawing, and we also receive suggestions to add functionality to the PDF export settings when that functionality already exists in the general plot settings.

Sometimes it is necessary to export a drawing to the PDF format as a grayscale or monochrome document. The usual way to do it is using plot styles: monochrome.ctb/stb and grayscale.ctb/stb.

With Teigha, you can export a .dwg file to a .pdf file that has PRC support.
The easiest way to see how it works is to use the OdaMfcApp sample application and the steps below.
1. Run OdaMfcApp.
2. Open a .dwg or .dxf file.

Sometimes Teigha subscribers ask: How do I export to a .pdf file only a certain part of a drawing instead of the whole drawing? Maybe it is not obvious because there is a default option ZoomToExtents in the PDF Export settings, and the same option is set by default in the PDFExportDialog of the OdaMfcApp sample application.
