extended profile preview idea
by Vasily Vl. Suhachev 07 Nov '10

Hello I am working on project with large profile and using XVI for preview result during editing "extend" commands. But it is very slow! XTherion hanged a minute on each load of XVI file, on each zoom-in or zoom-out. And XTherion can't zoom out less then 25%, so I can't browse overall picture Generating pdf with centerline is not an option too (station lines and labels overlapped each over, time assumed equally to XVI+XTherion) Hence, it would be useful implement new mode for "export model" command for export extended profile as a 3d or lox model. Such behavior have extend.exe from Survex -- WBR, Vasily

Generate XYZ coordinates of cave stations
by piotr_szukala 07 Nov '10

07 Nov '10

Hello! After surveyed few caves in Therion I've encountered some problems with their adjustment to other GIS software. I supose that extract XYZ coordinates of cave stations and their futher comparison with plan could be the simplest way to visualize cave data in other GIS software. Could you give me some advise how to generate coordinates of cave stations? Besides what is the adjustment method in Therion? Is it least square adjustment method? Best regards Piotr Szukała Poland

FW: white passage shadow under cave blocks out photo

. To: Bruce; Martin Budaj Subject: Fwd: white passage shadow under cave blocks out photo Forwarding your message to Martin, he is making PDF layers. Regards, S. ---------- Forwarded message ---------- Date: 10 October 2010 04:50 Subject: white passage shadow under cave blocks out photo To: Stacho Mudrak Hi Stacho I can post these messages onto the forum once it's back up and running. Just noticed that the relatively new feature that underlies the cave passage leaves behind a white 'shadow' when the cave map layer is turned off in the pdf. I make the surface image placed on the bottom so that the cave shows up nicely over the surface image. This means that the detail of the photo under (above?) the cave passage can never be viewed, as the shadow remains when the cave layer is turned off in the pdf viewer. Perhaps if the white shadow could be made to turn off with it's cave map, the a clean surface image could be viewed? Or is this incompatible with the original purpose of the shadow? Bruce

Multiple surfaces in Loch
by Graham Mullan 07 Nov '10

07 Nov '10

Further to the discussion about this I have just tried, to see what would happen, generating a lox file using one set of DEM data but two separate map images that cover different parts of the area. Only the second one gets picked up in the generated lox file, not both. Oh well. Graham -- graham.mullan(a)coly.org.uk 0117 9502556 or 07887 637064 (or 0844 2327803)

surface and loch
by marco corvi 04 Nov '10

therion accepts mere than one surface command, ie, many surfaces. the loch export writes all of them. loch reads all of them, and displays only the first ... but it is "ready" to display all of them. it would be nice to have all displayed ... possibly cropped to stay beneath one "special" surface, say the DEM. marco

XYZ co-ordinates and other things.
by Graham Mullan 02 Nov '10

02 Nov '10

Survex will generate a list of XYZ co-ordinates from a 3d file, so you "could" generate a 3d file from Therion and then run it back through Survex using the "convert for hand plotting option". For historical reasons, amongst others much of our data is in Survex format and is imported into Therion as 3d files. The Survex viewer, Aven, does have some capabilities that Lox does not, such as a simple method of measuring the distance between points and a direct read off of co-ordinates. Latest versions also have useful features such as "colour by date" and "colour by error" which I would like to see in Lox. One current problem is that 3d files generated with the most recent development snapshots of Survex, to version 1.1.15 are not recognised by Therion 5.3.4. Does this happen with 5.3.5? Graham
