OK, now I get the arrow, but there are problems: section line is missing
from first point to second: only begin of line and entire arrow is
shown, or sometimes, part of perpendicular line is visible, but then
it's on the passage. I think I'm missing something, but I can't figure
what it is.

a) cross-section is in its own scrap
b) on "plan" scrap I insert a point section with option -scrap scrap99
c) I draw a line section (curve) from aprox. where the bottom of
cross-section will be to desired point with option -direction end
d) what I get is on attachment

I guess there is a good reason to do it with a curve instead of a
segment, but it's a pity, because the segment is much more handier.
