Could more than one of the s3 archtypes come from the same target?
Last night I did a target that turned out to be an aircraft in flight, on my ST i had a long hollow tube (fuselage maybe), a wavy line (air) and also a smaller hollow tube with motion going through the center situated next to the larger tube. My good lady wife reakons this could be one of the jet engines. Hence my problem, Im not sure if two of the archtypes would come from the same target in this instance the plane.
I hope this question makes sense, Ive just read it through and I'm more confused than ever.

Yes. This is most common, however, when the target and the site are synonymous, or nearly so. Essentially, the 'site' template becomes a schematic of the target. Target geometry sessions are very useful in these cases.

Thanks, that has straightened out a few things for me.
