An aesthetic Question: Extended elevation surveys

I'm assisting with a local surveying project, but when I'm getting the extended elevation together. It's not easy to visualise it in a sensible way.


The problem is there are two drops from a higher level back down, one intersects another passage so really needs linking in extended elevation. Not in itself much of a problem, but I want to include the pitch up.


The problem with including the pitch up is that when you get to the top, you come out across a chamber facing back the way you came I'd like to represent the passages with the left hand passage on the left and the right hand passage on the right.


By looking at them in this way it will mean when they are linked in with the lower passages the left hand passage is over the right hand passage and vice-versa.


Does anyone have any recommendations? or should I just scrap trying to do an extended elevation and stick to projected elevations.


Just as a visual aid on what an extended elevation is, please find an example, not of the area i'm interested in right this month...

I think what you describe would look quite good Al but I'm afraid I haven't a clue - would be interested to know if you do work out a solution

Yeh, it's difficult: I've described it badly. A picture paints a thousand, even if I choose to hide all the names ;)



I've attached it below. essentially you enter via the eastern passage at the lower level, then up into the higher level from the western passage on the lower level and so you turn 180 to look at the Northern passage
and the south south eastern passage .


south south eastern has a connection to a lower level. but I just cant fathom the best way to visualise this shift in perspective!​

Hmm mulling it over I might just put a great big split in it halfway up the pitch and have a caver looking away and caver looking towards on the survey. but i'll have to have a think as to whether this would make it easier to visualise.
