Revit Design Automation engine 2022 starts to support exporting PDF, we mentioned this within my previous blog. And to make it clear, I just made a sample application to showcase the usage.
The source code of sample is at https://github.com/Autodesk-Forge/forge-revit2pdf, and it demonstrates how to export views and sheets from Revit to PDF, you can export different types of view.
As a live demo sample, for cost consideration, the website(https://revit2pdf.herokuapp.com/) adds the limitation that only 5 views are supported to be exported to PDF, but you can easily remove the limitation from the plugin code.
