Dear Qaisar, I am not familiar also with AutoCAD formats may be one of list member knows how you can keep elevation info in dxf file. I can only say you may add elevation data manually if you can save your ArcView or dxf file in *.erv format.
-Save your vector file as *.erv - Open "Annotation Tool" Bar - click on one of topo contour - click "ABC" button on toolbar while topo contour chosen - enter its elevation value, press "Apply" button - choose another contour and enter its value via "ABC" Button It is quite time consuming procedure but resulted *.erv file can be used as input for gridding wizard.

I know that ErMapper can create grid from dxf file. I did the same. But my question is that how the ERMapper will know that which field should be used for elevation value. for examle when we create grid from any satellite data, it uses the reflectance value. but when we are giveing any vector file as input how it will use values > Qaisar > ----------------------------------------------------------- To make changes to your subscription, please visit our website, http://www.ermapper.com/technicl/ermapperl/index.htm
