How can I clip a raster to the outlines of a polygon?

I thought I could trim an elevation raster to the outline of a non-rectangular. polygon with Copy Raster if I used the polygon as a mask in the environments, but I just got the entire raster in the output.  And I don't see Mask in the Environments section of the help for Desktop 10.3.1.  


I thought I had done this before.  The only way I could figure out how to do it was create a new terrain out of the multipoints I have for the  smaller extent, and use the mask polygon as a soft clip in the terrain generation.  The I ran Terrain to Raster.  Is this the only way?
