The main Teigha PRC example for “how to create” is the OdPrcCreate example located in the \Prc\Examples\OdPrcCreate folder. The release package includes a prebuilt OdPrcCreate.exe application in the “exe” folder. Also a project file is available in the release packages (for Microsoft® Windows®). So it is possible to start the prebuilt application or debug it using Microsoft Visual Studio.
With the new release of Teigha 4.3.1, you can attach digital signatures to your .dwg files and validate a .dwg file’s digital signature. A digital signature indicates who the file came from and the file’s state when the digital signature was created, and validation confirms this information.
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.
