@User: The "m" instead of "x" is certainly going to cause a problem. Netgen is supposed to be able to figure out that "700000u" is equal to "0.70", though, which is why I was hoping that you could post the error message where it states the property error so I can figure out why that doesn't work. The weird "700000u" number comes from the fact that magic is used to generating microns in the output and so I had to scale up the values in front of the "u" to get the units to come out correct. Some time when I get the chance, I'll modify the code in magic so that it will automatically figure out that removing the "u" and scaling down the value makes a more readable output.
