Custom Family Type Catalog Exporter

Ok, so here is what I have come up with, and what is still not working just right.

  • I exported a Type Catalog from Revit directly and it was actually encoded as UTF-16LE

  • This export maintained special characters / letter as I expected, but broke for Parameter Names / Values with commas.

  • I refactored to encapsulate either of those values when they had a comma

  • I refactored the write to use the codecs class rather than the stream writer.

  1. This enables us to encode as we want to the UTF-16LE or any other as needed
  2. Problem is that for some reason it is hiding an invisible character at the beginning of the text file that is breaking revit.
  • This can be solved in two ways:
  1. Save As from notepad as ANSI
  2. Delete and replace the very first comma on the first line of the file.

There would probably be a way to open and replace the comma, but my first attempts saved the file back as UTF-8 or something other than what it was so I stopped thinking it may need a completely different approach.
