I am importing csv files which has:

nodenumber,    x-coordinate,    y-coordinate,        pressure
         1, 3.120017000E+01, 4.856500000E+00, 4.426002436E+03
         2, 3.123076680E+01, 4.856500000E+00,-1.081903081E+03
         3, 3.126131470E+01, 4.856500000E+00, 6.745413607E+02

Problem is that if I change the girder to a shell, it might change from a 3D to 2D. Therefore, x-possition changes.

About the (-1), I think its a really good idea. Just wondering if as possition changes, it would be propertly transfered.
