Hi!
I am currently doing something similar to the ModelAccess_Test sample plugin. On very large files, it's quite slow.
I know archicad probably isn't thread safe, but is it safe to use multiple threads to read elements, their attributes and content, into my own (thread-safe) context?
I wouldn't expect to handle multiple threads writing to the model in parallel, but just reading data without changing anything inside the model seems like archicad might be able to support?
