Hi guys, I have created a surface in vol 1 and I want to divide vol 1 into upper and lower volumes using that surface as a dividing surface, how do I do that or can I do anything about it, I hope you can give me some advice, appreciate it. Here is a prototype of what I did.`reset

brick x 100 y 80 z 50

move vol 1 x 50 y 40 z -25

create vertex 0 0 -25

create vertex 0 80 -25

create vertex 20 0 -20

create vertex 40 0 -30

create vertex 60 0 -20

create vertex 80 0 -30

create vertex 100 0 -25

create vertex 20 80 -20

create vertex 40 80 -30

create vertex 60 80 -20

create vertex 80 80 -30

create vertex 100 80 -25

create curve spline vertex 9 10

create curve spline vertex 9 11 12 13 14 15

create curve spline vertex 10 16 17 18 19 20

create curve spline vertex 15 20
