For Roof Wizard V8.2 and onwards, the user doco is all online and available at www.help.applicad.com. Also, the help files are directly linked from the respective dialog boxes within the software. Click the [?] or [Help] and your web browser will open and take you straight to the appropriate help files for that function.
It would be helpful to also turn on the AppliCad Instructor (Help > Instructor from the pulldown menu). The Instructor dialog is also linked to the online manual.
Some versions of Roof Wizard v8.1 were shipped without the Learning Guide included in the C:/AppliCad/Roof Wizard/Manual folder. If you missed out, you may download it here - www.applicad.com/docs/LearningGuide.pdf
Once downloaded, save into the C:/AppliCad/Roof Wizard/Manual folder so that you can open it from within the Roof Wizard software - Help > Manuals.
