After upgrading to 10.5.1 operations that have worked successfully with extrude between now fail with the following message:
Executing: ExtrudeBetween lith4res_tin lith5res_tin areacols2 C:\phil\Dropbox\CEG8705\run2018\tins\oilpatch6.shp

I have tried changing the resolution of the extruded layer (making it physically smaller and making number of features less) but this has not helped.
Reducing the TIN complexity by resampling the raster and reducing raster resolution by 10x also does not help.
The same data worked fine in 10.3.1 and 10.4 but fails on 10.5 and 10.6. I have not managed to find a workaround.
I came across this error while attempting to extrude a polygon between two TINs. My issue was that my polygon had too many vertices (I drew it with the free hand tool). I used Simplify Polygon to make it have fewer vertices and the tool ran. Not sure if that will help in this scenario, but was a similar issue I think.
