Thank Edgar so much!
in this case(attach file) i already did that, but almost another case i cound not do that. So i think the probem is not 2D or 3D.
i would like to attach both of them at here to compare each other.
i saw both of them are same, but the results are completely different.
Please let's me know what is the problem at there.
Thanks so much
