Ok, just as I thinked, unfortunately. The strange thing is that I can ever see splay shots, but the wall tubes become invisible only when I use together, in the same survey, both type of data (with splays/LRUD). And even the command "interpolate missing walls", doesn't work in any way when using only splay shots data. Loch could be a really nice application. Hope some skill people could work on it's development, it is a pity to leave it on the middle of its way, or maybe at 90%. Thanks to all.
