Without touching the keyboard or mouse you can watch the cursor move to the menu, make selections, move to the drawing area, draw a box, move back to the menu, select another command, move back to the drawing area and resize, flip the box or whatever. If you're learning CAD this is a handy way to figure out how to perform some of the functions described in the tutorials. I remember puzzling over my AutoCAD book trying to figure out just what they were trying to tell me to do and not being able to actually perform the functions based on the instructions in the manual. Since the index is quite thorough you can find the information you need. However, even though many other software programs come with manuals based on a tutorial or lesson format, I would like to see a thorough, alphabetical, reference type manual included as well.
Many software programs come with both types.
I think you need them both. I'd also like to see a troubleshooting appendix and somewhere, the phone number for tech support listed. Don't get me wrong, the manual is quite good enough and I found answers to almost all the questions I had. But some areas could be a little more detailed. Printer information is scanty.
