After using the "measure" tool to get measurements to plug into the spreadsheet I created that generates PANOSE strings that can be pasted into the font information dialog, I think it wouldn't be overly difficult to provide a wizard that would make the measurements even easier, and then display a report that can be copied and pasted into such a spreadsheet. So, to be clear, I don't want FontCreator to be able to do everything, just help with the measuring.
A lot of the measurements require me to zoom in for accuracy, then read the info off the measure box (sometimes not the full measure, but instead the horizontal or vertical component). But, if the functionality of the "cut contours " tool was combined with the "measure" for this wizard, it would allow measurements to be done at normal zoom, with the two endpoints of the "cut" being used for the length.
There are only 13 glyphs that need to be measured in a Latin Text font to get complete PANOSE information. A wizard could present each glyph, then step through the measurements for that glyph, and the user could draw the lines. Other advantages of a wizard would allow some of the more complex "tangent" measurements (like OutMid and InMid on the uppercase O) to be done with a simple line draw that indicates the angle, plus the wizard could constrain the start point on some measurements (like the ones that must always start from the center of the glyph, or must match the italic angle set int the font properties).
Even a wizard that only did the "easy" but often incorrectly set PANOSE features (weight, proportion, and contrast), which require only 15 total measurements on 6 glyphs would be a great help. With a wizard like this, I could probably get correct PANOSE for 20 fonts an hour, instead of the 5 or so I can do now.
I know this would be a really low-priority enhancement, but I don't think any such tool exists anywhere, so it would lift FontCreator even farther into the "professional" arena.
