Hi Raj, Another thing. You should do that to set origin and normal.
var plan = sliceFilter.getSliceType(); plan.setOrigin(0,0,0); plan.setNormal(1,0,0); in fact the methods SetSliceOrigin/Normal are helper methods on python objects and not properties. You can notice it because of the capital S in the set. This must come from the python trace. If it was a property in python it would have been written: sliceFilter.SliceNormal = [1,0,0]; Hope this help you to understand how it is working underneath and how to easily convert Python generated code into similar JavaScript one.
