Thanks, I'll get into the website this weekend, most likely.
I jumped into the deep end with the nextEngine scanner. (Perhaps into whitewater rapids is more accurate). Attachment should make meaning clear.
Pictured is a composite of some 75 individual scans. The program claims it is within 0.009" accurate.
Output to Blender without issue for cleanup.
Going to use that (Ed: i.e. the engine scan) for a set of tutorials.
