[Therion] x-section lines

[Andrew Atkinson]

hi all

I have got my cross sections where I want them, but now working on the 
line type. The picture on page 52 of the Therion book shows the type of 
line indicator I would like on my plan, but I cannot find a way to do 
it. I have a solid line across the plan with a arrows on, but cannot get 
it to hide the bit in the middle. I've tried
-place bottom
but this seems to make no different

While searching the book, examples and wiki I have come across a couple 
more things that I cannot fathom the instructions for

On the section line, all the other direction options work but I cannot 
figure out
-direction point

I get the error
  -- no line point specified
and I cannot find a way to specify the point.

also in the book p27 note 24

"Line showing cross-section position. If both control points of a 
Bezier curve are given then the line
is drawn up to the perpendicular projection of the first control point 
and from the projection of the
section control point. No section curve is allowed."

I cannot work out what this means

hoping you can help

thanks

Andrew
