I am getting 99999 error when running the 'Add Surface Information' tool with a 3D polygon. I have tried adding Z_MIN, Z_MAX, Z_MEAN, separately and in combination but it will not work. I get the field added and all Null values. I know this was supposed to be fixed in 10.2 but is it fixed? I am using 10.3.1 and I also tried in ArcGIS Pro 1.1.0 (same error).
