1m Grid file to Raster (9m grid)

Hi All,

I have been supplied a 1m grid file as a csv, and I have created a simple model (see screen grab) and I create a TIN, crop this tin, then export to a .TIF file using 'TIN to Raster' tool. My end result for this process is to be able to hand this .TIF file to our engineers, which can be imported very easily into AutoCAD as a 3D surface.
Unfortunately, the exported TIF is in a grid which is approximately a 9m grid, see the difference on the attached screen grab of the detail given to us (green dots) compared to the data output in the TIF file (grey squares). I seem to have lost quite a lot of detail in this conversion process.

I believe data loss must be happening in the last of the tools (TIN to Raster), as if I just use the Create TIN tool I get a 1m gridded file which has not lost any data - see screen shot below.

Does anyone know why my .TIF file is not holding all inputted data?

Ben, Have you considered using the Raster Interpolation tools to go directly from the points to a tif raster? (ie: IDW or Kriging)?
