<p class=MsoNormal style='margin-bottom:12.0pt'><font size=3 color=navy
face="Times New Roman"><span style='font-size:12.0pt;color:navy'>></span></font>Simple
scrap, but why does my lox model appear to only show the walls when seen from
the wrong side?<br>
<br>
<font color=navy><span style='color:navy'>></span></font>I have checked that
the wall lines all have the yellow tick pointing inside the passage. But half
my passage appears in the <st1:place w:st="on">Loch</st1:place> viewer to only
show the wall from the inside face, not from outside the model.<br>
<br>
<font color=navy><span style='color:navy'>></span></font>Very simple data
file contents are as follows. The survey stations are being imported from a
survex 3D file. But I am only using 2 survey points to scale the scrap, so you
should be able to create any two points to substitute the survey data.<br>
<font size=2 color=navy face=Arial><span style='font-size:10.0pt;font-family:
Arial;color:navy'><br>
I have done this with scanned paper files a number of times.</span></font><font

<p class=MsoNormal style='margin-bottom:12.0pt'><font size=2 color=navy
face=Arial><span style='font-size:10.0pt;font-family:Arial;color:navy'>Always
if I use two points the lox files come out as you describe, or with vertical extensions
from the actual cave position to the surface.<o:p></o:p></span></font></p>
<p class=MsoNormal style='margin-bottom:12.0pt'><font size=2 color=navy
face=Arial><span style='font-size:10.0pt;font-family:Arial;color:navy'>A
solution that has worked once, but not tested yet on the others is two break
the drawing into more than one scrap, and have at least two points per scrap.
This way the therion drawings and lox come out the same as with a conventional
survey.<o:p></o:p></span></font></p>
<p class=MsoNormal style='margin-bottom:12.0pt'><font size=2 color=navy
face=Arial><span style='font-size:10.0pt;font-family:Arial;color:navy'>It seems
that two points, one scrap is too minimalist for the current implementation.<o:p></o:p></span></font></p>
