Do you need some support for this?

In any case, I stopped developement of therion 3D viewer. I came to conclusion, that TclTk is too slow for that... I have started new project, but it will take some time again, there are a lot of problems.

I have one question. Would it be possible to enter to survex .3d format an arbitrary triangulated surface, not just LRUD data?

When we were doing this, we marked scrap ends by red lines on the scan images. In fact, we usually prepare bitmats, that we are using as background. We have original scans at 300dpi, but for backgroud, we subsample them to 150dpi, adjust contrast and brightness, draw scrap ends with red line etc. If some detail is not clear, then we have a look at original scan.

Try "Auto adjust" button in drawing area toolbar :) The scrollable are is defined by user, when you insert picture, it is not automatically adjusted (probably should be).

It is a bug somewhere deep in Tcl/Tk (it happens only from time to time on Linux, each time after longer compilation on Win32). I have no idea how to solve it (I have tried reduced it a lot, but it still happens).
