Andrea Rather than try to explain I will include an example of one I have done. This one has no real survey, only a scan of an old map, but hopefully you can figure it out. One confusing thing about my example is the large amount of spurious data that has been commented out, although it may also give you a clue as to how I set my data out for a more comprehensive cave (which continues to be my biggest challenge - although I do have a system now). Copy all the attached into a folder of their own and then play around. I have left out the scan of the cave as it is very large. Just add your own jpg image to the folder - a smiley face say - and name it PerserverancePlan1.jpg To get this to work, you will need another folder at the same level as the one you just made named 'Outputs' (otherwise you will get an error CP01) AND you will need yet another folder 'StdFiles'. I'll make a second post with the contents of 'Std Files' I've added the .thc extension because I use Windows, and once I've associated the thc extension with Therions mysterious 'Wish Application' I find that using Therion from the OS becomes much more user friendly. Just double click on the files - the thconfigs open in the Compiler and the Layouts open in the Text Editor. Much better! Hope this helps Bruce PS: It occurs to me that, in my th2 file I have added the image to the 'background images' box in the menu area on the side of the map editor. Perhaps it would be better in the 'background sketches' part of the 'scraps' box. Maybe then I could output a scanned cave AND a ground surface image in the same pdf file?? I'll play with it again one day perhaps. _____ From: therion-bounces@speleo.sk [mailto:therion-bounces@speleo.sk] On Behalf Of andrea.marassich@email.it Sent: Saturday, 11 October 2008 2:59 a.m. To: therion@speleo.sk Subject: Re: [Therion] scale image Sorry, forgot to mention two stations of my centerline are located into the image I can draw and which is without scale. hope this give you enough information. best, Andrea Marassich Hi, sorry to bother with a beginner question, but cannot make it even reading through the archives. I have a .th file with centerline and .th2 file with his scraps. Now I should add to this a th2 file with an image of an old survey. I drawed walls and all objects in the scrap but do not know the scale and do not have original data of the centerline. How can I put together my centerline/scrap of known scale with this image? Do not know how to do it and I'm having dificulty understanding how the scale process is working. could you help me on this? thanks a lot Andrea Marassich
