Add .Pat files to Revit project

[n_mulconray]

Is there support in the 2019+ API to either directly load a .Pat or to generate a .Pat from a text file? I would show the items in listview and then use drag and drop to load some standard .pat that would be visible within a project.

Revit doesn't load or store .pat files. It just reads them once to create its own patterns. You would have to do the same by reading the .pat files and creating FillGrids for each FillPattern.
