Why would they give you an assignment that needs 3D Analyst if they don't have a license? Are you sure that you don't need Spatial Analyst instead? Check for that extension. Also, try the License Server Administrator, and check the Availability tab ... View more

spend a couple of hundred dollars on ET Geowizards, well worth the money for us poor ArcGIS Basic users. http://www.ian-ko.com/ You can download it for free and use the "non-free" tools for a while. Use Spatial Relations and Allocations\Spider Diagram - Attribute Link Ensure that there is a field in each of the intersection and void polygon layers that have identical values (I created a field in each called NewID and populated all with zeros. If the are unique it will only do matching polygons) Eliminate all of the unwanted polylines in the resultant shape file (i.e. lines > 5 m etc.) Use resultant polyline shape file with the Polygon\Split Polygons with Polylines tool to split your road polygons. ...

Whatever you end up using, dissolving the contour lines by height might help further. I use FGDB for such things. ... View more

Does anyone know of the same type of script or tool, but point to polygon instead? ... View more

Found it, but it's point to point, not point to feature unfortunately. http://arcscripts.esri.com/details.asp?dbid=14908 You need to find a script or tool that will draw a polyline from each intersection point to each "void" polygon to get started. ... View more

pssst...hey bud... I recall using a tool a couple of years ago (it escapes me now) that took a point file, and created a shape file layer of polylines that gave minimum distances from each point to each polygon in the other layer (in this case the polygons between the road polygons). This looks like what was done here, but delete any polylines with length greater than the road width, and use that polyline shape file to cut the road polygons. I think is was one of the spider diagram tools in ET Geowizards ... View more

Try Conversion Tools\From Raster\Raster to Polygon tool, use Simplify Polygons, then Dissolve them. ... View more

looks like they might have used a distance to polygon type of thing using the polygons between the roads, then used the resultant lines to cut the roads ... View more

That's the messy part. I think you're in for a lot of manual work here either way, unless you have a convenient road segment polyline file with width data included. ... View more

I agree with Tim, but it could get messy. ... View more

Do you then need to name the polygons etc? What do you fully need as a final product? ... View more
