建立interface时碰到的问题

rocktangzc

我写的代码如下，想在group 1 与 group 2 之间建立interface，但是总是看不到interface，请哪位高人指点下啊，谢谢！
我需要用interface 1 wrap 建立模型，因为以后方便建立比较复杂一点的interface.

new
gen zone uwedge size 3 3 3 &
    p0 (0,0,173.2)    p1 (50,0,259.8)   p2 (0,200,173.2) p3 (0,0,346.4) &
    p4 (50,200,259.9) p5 (0,200,346.4)
group zhu1
gen zone brick size 3 3 3 &
    p0 (0,0,173.2)     p1 (200,0,173.2)  p2 (0,200,173.2) p3 (50,0,259.8) &
    p4 (200,200,173.2) p5 (50,200,259.8) p6 (150,0,259.8) p7 (150,200,259.8)
group zhu2 range group zhu1 not
gen separate zhu1
interface 1 wrap zhu2 zhu1
plot create view_int
plot add surface
plot add interface green
plot add axes red
