TopotoRaster - Creating a 'Boundary Type' for input

Discussion created by christi_nelson on Nov 9, 2011
Hi there,

I want to use the TopotoRaster (Spatial Analyst) tool to generate an elevation raster.  I have a contour line feature class to use as the contour (elevation) input Type.  I need a Boundary input Type as well (to represent the outer boundary of the output raster).  For the Boundary input I need to create a boundary polygon for the contour lines feature class(this will end up being a multipart polygon, fyi).   This cannot be a bounding envelope, it needs to be a bounding outlines of the feature class itself.  How can I do this in ArcGIS10 (ArcInfo level)?
