Thinking about this I'm struck my the notion that the model of the example is wrong, a line doesn't have a cm length and a in length, it has a single length which can be described in either cm or in. I know I'm criticising the example and not the point, but would a model placing the different units of measurement in a Length object change the problem?Received on Monday, 16 June 2003 07:10:47 GMT
