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? =============== Bill Gee On 12/3/24 09:02, Tarquin Wilton-Jones via Therion wrote:
For this case, though, that will not work. There are no passages in this mine. Think of a large room in a building with support columns in the middle.
You have to change your mindset. It *is* a series of passages. They are just very short before reaching the next junction. And just like if you were surveying a cave passage 100 metres wide and 50 metres long, you have to draw the walls, and close the gaps between them with an outline. See attached (case 3).
