As an alternative to the pointing frames, I suggested using a series of small plumb bobs to capture and transfer dimensions to quickly make flat 2d patterns for individual stations. Measuring draft or undercut needs to be done carefully from one of the plumb lines but isn't a significant problem. It's very cheap and accurate, although not necessarily instant numeric data for a computer.
Regarding your computer data desire- On my shelf of tools I thought I might use but never really have is a (think it's a TWA-related symptom....) is a hand held laser distance measuring device. It's still basically nib somewhere around here and not sure how precise it is. Maybe something like that, utilized along a consistent framework, would provide more hi-tech compatible numbers for developing an e-file without as big an expenditure as some other equipment?
Still, all it would be doing is exactly what the plumb bobs do...
