Thank you Diolma and Conniekat, I'm sure taht will get me going. I tried downloading greenlees videos but it was very slow,and I started hiting keys got stuck and stopedit. I'll try again later. I  had a look at the other link and that looks very promising.  I dont think I got any tutorials with hexagon - I got it in March when DAZ sold it for $2, so maybe this was a limited version. Or maybe I should download it again,hmmm. (I don't like reference manuals but i do use tutorials suplied with programs). Anyhow, it seems that Hexagon has similar terms to those I  remember from Strata, so probably will be good!

Well, I certainly got a lot of usefull info.(See Conniekat, I knew It was a good think to ask you!)
