Who can tell me the local help documentation solidworks (HTML Help (.chm)) is a compilation of what software?
It is Help & Manual 7 or Adobe RoboHelp or other again?
That's probably only guys from SolidWorks can tell you. But can I ask why do you need this information? If you are going to build your custom help and just asking the suitable software I would suggest you the following options (those are free)
HTML Help Workshop: Download HTML Help Workshop and Documentation from Official Microsoft Download Center
If you need an API related help the best option is Sandcastle: Sandcastle - Documentation Compiler for Managed Class Libraries - Home . It can read all html comments in .NET applications and generate the API help (CHM) file.
I am pretty sure it's Help Studio from Innovasys. (Help Authoring Made Easy - Innovasys )
