Sampling raster values along some random transects

[AsimBiswas]

Hi, I am a early user of ArcGIS. I am using version 9.3. I have a digital elevation model. I would like to sample the elevation values along some randomly selected transects. The transect does not have physical entity. From the map, I can see and select the length and direction of transects. In doing so, what I can do. How I can extract the elevation values along those transects ( of course, first I have to select the transect, how?)?
Thank you very much for your help. I have spatial analyst toolbox.

Do you have access to a 3D Analyst license? The 3D Analyst toolbar has functionality to do this.
