I can't subtract one object from another

SketchUp

There are 2 solid objects. But for some reason, in one position, I can’t subtract one from the other. But if you significantly move one object lower, then everything turns out, what is the reason?

Scale it up .x10

SketchUp api solution

model = Sketchup.active_model
selection = model.selection
comp1 = selection[0]
comp2 = selection[1]
pt1 = ORIGIN.transform(comp1.transformation)
pt2 = ORIGIN.transform(comp2.transformation)
pt3 = [[pt1.x,pt2.x].min,[pt1.y,pt2.y].min,[pt1.z,pt2.z].min]
tr = Geom::Transformation.scaling(pt3, 10)
tr2 = Geom::Transformation.scaling(pt3, 0.1)
comp1.transformation = tr*comp1.transformation
comp2.transformation = tr*comp2.transformation
result=comp1.trim(comp2)
result.transformation = tr2*result.transformation
comp1.transformation = tr2*comp1.transformation
