My elevation data is a floating point tif. I have a road for which I need to calculate the elevation profile, but I can't see the tools to do this.

Can I do this with ArcGIS, with spatial analyst/3D analyst?

How to create a profile graph from digitized features of a surface

1.In ArcMap, click the Layer drop-down arrow on the 3D Analyst toolbar and click the 
surface that you want to profile.

2.Click the Interpolate Line button Interpolate Line button.

3.Click the surface and digitize a line you want to profile. When you are finished added

    Thanks.....just for others that have the same problem as me...I had in fact created the 3D line, but what I didn´t know is that the line segment has to be selected before the tool activates. – Robert Buckley May 9 '12 at 15:48
  • what if the drop down layer is not active? what do you do to change that? – user9715 Aug 23 '12 at 10:05
