SNAP Reference Guide — not browsable online (structural surprise)

Unlike every other book in this group, the SNAP Reference Guide is not rendered on docs.sw.siemens.com at all — the topic page is just a stub that says:

"The SNAP Reference Guide is delivered in Microsoft Compiled Help format (.chm). Windows security enhancements prohibit opening .chm Help files across a network, so you must install this .chm file on your computer... Click here to download the zip file... download SNAP_Reference.zip to a local folder and unzip it."

So there is no HTML content, no PDF, and no left-nav TOC to walk — the "book" is a link to a .chm download (SNAP_Reference.zip, NX 2212 Series). .chm is a proprietary compiled/indexed help format (basically a zipped, indexed set of HTML pages + a binary index) that cannot be scraped via the browser the way the other 10 books can — it would need to be downloaded and opened locally in the Windows CHM viewer (hh.exe) or unpacked with a CHM extraction tool, which is out of scope for this browser-based extraction pass.

Not extracted. If full SNAP function-by-function reference content is needed later, download SNAP_Reference.zip from this topic page and open the .chm locally, or use a .chm-to-HTML extractor to convert it to scrapeable text.
