I get the following error while creating TIN in memory : ERROR 999999: Error executing function. Can't save to disk (check for space, write permission, or name). Failed to execute (CreateTin).
I don't have any issue with writing any feature class in memory, I wonder why it doesn't work for TIN.
TIN = arcpy.CreateTin_3d("in_memory/TIN", Coordinate_System, "XS_lyr P001 hardline FID", "DELAUNAY")
When I remove the "in_memory/" and just save it on local drive it works fine.
