[Therion] Entering survey sketch without walls

[Bruce Mutton]

Bill

I've been misleading you (and everyone).  I should not multi-task quite so much.  I will try to rectify the situation tomorrow with a sketch.

 

In the meantime...

line wall -subtype invisible is what should be used for the open ends of scraps in your example, and should allow semiautomatic joins.

line wall -visibility off will preclude the possibility of semiautomatic joins, but does have a use case in large open voids that need to have a scrap join where there are no (real) walls at all.  Manual point joins will be required across those boundaries.  A sketch tomorrow…
