PolygonZ to Raster

Hi again,

I have a shp file with PolygonZ and I want to convert each of these (polygonZ) into rasters.

Any idea how?

You can convert the polygon to a raster with the Feature to Raster or Polygon to Raster. Be sure to specify the elevation of the polygon in the field when prompted in the tool. This will make each of the polygons one raster value. You cannot use the multiple vertices in your polygon, you will have to export them as points in order to interpolate the edges. The polygons will have one value in raster form for that contiguous polygon.

Honestly this is painfull.
This was my problem.
Feature to raster only works with points.
So how do I get a raster that maintains the 3d character of the polygonz.

I have a long strip (polygonz with four vertices). This strip is going uphill so the two z on the down-side have the same value and the other two on the up-side have the same value but different from the ones at the down-side.
Nothing more. Think of it as a straigth ski slope. This is my polygonz. How do I convert it to raster (I will check the cell size) that has z values (pixel values) that are interpolated from the polygonz.

Thanks a lot.
