[Therion] Entering survey sketch without walls

[Bill Gee]

Hmmm...  I thought about doing it the way you suggest.  I will have to 
try it to see how it works.  Testing required1  :-)

I think a lot would depend on how the survey shots are laid out.  I 
think it would require several survey stations around each column.  The 
scrap boundaries would then be the surveyed line between adjacent 
columns.  And I suspect there would be a very large number of explicit 
line joins.

Some adjustment, of course, since the columns are not laid out in a 
regular grid.  There would be some triangular scraps.

Would it work better to set a survey station in the center of an 
intersection and then do splay shots to the columns?  Or set the 
stations on the columns?
