Yes, I've been in the same position, but assumed that this feature would be
too much to ask for. If there are side passages running towards or away from
the projection angle, they tend to get turned inside out when they flip from
'running slightly left' to 'running slightly right'.  Still, most passages
will be OK.

It would be nice though.  When I first used Therion I tried to use the same
elevation drawing for both a projected elevation and an extended elevation.
Before I understood that this was not the intended functionality of Therion.
The results were so so.  A bit of distortion here and there as you can
imagine.  Xavier's idea would not make this possible, but would ease the
process of drawing the second elevation based on the first.
