Two problems: merging bsp and making curved bsp

[[~]RUFX[~]RoninMastaFX]

I am still confused on how to merge bsp and no idea on how to make curved bsp. Aalexanderrr said for Merging BSP that you have to do Polygons>Merge, but it never, ever worked for me (I must be doing something wrong), and the curved bsp is well beyond me.

Any sort of tut would be good for me.

You cannot merge surfces cos you have to align them to the wall first. About curves: you should use 2d shape ed, you make nice curve and then transform it into the brush , rescailing and rotating it in order to fit in nicely.
I will write a tut on this matter as soon as I get back.

OMD, how can I explain that? hmm
The surfaces for merging (but first Align to floor [usually]) have to be on the same height or have to be the same angel ... something like this




and the same texture!
