As I mentioned in my earlier review, all the links for Hexagon’s documentation are currently broken. Since then, I have noticed a fair bit of search engine traffic of people looking for documentation, for good reason too… this program is downright confusing!
I have noticed that although all of the links to Daz3D.com are broken and you can’t use the help menu in Hexagon itself, the help files are actually installed on your computer! Go to the folder you installed Hexagon 2.5 to, in my case it was C:Program Files (x86)DAZ 3DHexagon2docs. Inside should be the PDFs you are looking for.
In case you cannot find them, I will make them available here ( hopefully this is ok… ).
Keep in mind, these are the manuals for Hexagon 2.1 and appear to be about 6 years old! That said, it’s better than nothing!
