I came across this image on http://desktop.arcgis.com/en/arcmap/latest/extensions/3d-analyst/choosing-the-3d-display-environment.htm
I would like to create something similar that shows the below ground underneath my 3D TIN surface so that it looks like it's been sliced out.
However, I can't seem to find instructions for how to do this, what it's called or a tool that can generate it.
I've tried a few things such as the "extrude between" tool but I don't have a TIN to represent the bottom of the block to extrude between. I only have a TIN for the surface. I do have a polygon feature with the z value of 1m which is the exact extent of the TIN surface. I could use that as the base to extrude between but only get a 999 error when I try to generate TIN from it, probably because it is a flat plane rather than an irregular surface.
Are there any tools or work arounds for creating this?
I know it can be done in non-spatial software like InDesign if I export the surface and do some graphic design on it but my main skill in in GIS and it gets expensive and time consuming to work across multiple software packages.
