Basically, there is no conversion of sketches from one projection to another. You have to do the work yourself or accept any distortions that a fudge might incur.

Very simple example, just one shot:

file test_levation.th

survey test_elevation -title "test elevation"

input test_elevation.th2

centreline
units clino compass grad
data normal from to compass clino length
extend right
1 2 5 20 10
endcentreline
endsurvey

And outputs as orientation extended and elevation 0. The converted sketch is not what I want to see. So there is not way how to automatically convert extended sketches to elevation map. But if the orientation of elevation view will be not too far from perpendicular to the centerline shot, the result could be acceptable. See third image.
