[Therion] bedding planes on cross sections?

[Carlos "Guâno" Grohmann]

I was drawing some cross sections of a recently mapped cave, but  want
to draw the lines representing the bedding planes of the rock. If I
just draw them outside the passage walls, they won't be shown on the
final map, and if I draw a invisible wall outside the passage and the
bedding planes lines, the interior of the passage will be trated as a
pillar, since there will be a wall inside a wall.

So, is there a way to draw lines outside of a wall and get them to
show on the map?

BTW, I just added some projects we are working with Therion here in
Brazil in the Wiki.
