In opencascade, if we want to see a breakout section view of a part(eg. http://lh3.ggpht.com/_jES0ooeGYF0/Seqr1ZKrYfI/AAAAAAAAAag/QZZteyobgh8/se... ), it seemed that we can only use boolean operations to cut off the part solid. but boolean operation is quite time-consuming and not robust enough. I have also try to use clipping plane in V3d_View, but clipping plane doesn't generate cut sections so the cut view of part solid is shell alike(http://lh3.ggpht.com/_jES0ooeGYF0/SeqnCcQPdLI/AAAAAAAAAas/kkFfQ7OiNGk/s9...).
Could any one tell me that in visualization module, if there is a fast way to view breakout section view without use boolean operations? Thanks very much!
