- In Jscript, the array needs to be converted to safearray before you can set it on ICE attribute data. Check out the code below for the conversion. - As a workaround for setting MaterialID, you can store the data in a custom attribute, then use ICE to read from it and set MaterialID
function getSafeArray(jsArr) {
var dict = new ActiveXObject("Scripting.Dictionary");
for (var i = 0; i < jsArr.length; i++)
dict.add(i, jsArr[i]);
return dict.Items();
}
//to a safe array
var safearr = getSafeArray([1,2,1,2,1,2]);
//back to a js array
//var jsArr = new VBArray(safearr).toArray();
cube = Dictionary.GetObject("cube")
attr = cube.ActivePrimitive.Geometry.AddICEAttribute("CustomMaterialID",
siICENodeDataType.siICENodeDataLong,
siICENodeStructureType.siICENodeStructureSingle,
siICENodeContextType.siICENodeContextComponent2D)
attr.DataArray = safearr

Subject: Re: setting ICEAttribute.DataArray in JScript
Last time I tried, I gave up on JScript (it seemed impossible) and got
something to work in Python.
si = Application
from win32com.client import constants as C #
win32com.client.constants
oObj = si.Selection(0)
oICEAttrMats = oObj.ActivePrimitive.AddICEAttribute("MyString",
C.siICENodeDataString, C.siICENodeStructureArray,
C.siICENodeContextSingleton)
oICEAttrMats.DataArray2D = ["a", "b", "c", "d"]
x = oICEAttrMats.DataArray2D
print x
print len(x)
print len(x[0])
print len(x[0][0])
for d in x[0][0]:
print d
# (((u'a', u'b', u'c', u'd'),),)
# 1
# 1
# 4
# a
# b
# c
# d
