[Closed] 3dsmax script // spline union boolean

Hello.

I need some help. I’m trying to do a boolean operation with shapes and i’m stuck :banghead: . I don’t know very much about scripting, now i started to learn some of 3dsmaxscript.
So i’ve created 2 circles, attached them in one shape object and now i want to do a union operation. Here is where i’m stuck.

Thank’s for your help!

c1 = circle radius:20 
c2 = circle radius:20 pos:[20,0,0]
convertToSplineShape #(c1,c2)
addAndWeld c1 c2 0
select c1
subobjectLevel = 3
setSplineSelection c1 #(1) keep:false
splineOps.startUnion c1
