Create Tin with multiple input features

[RileyCotter]

This piece of code works just fine in my script and the TIN is output with no problems

arcpy.CreateTin_3d(TIN_name, coordsys, outputFC + " Shape.Z masspoints", Delaunay)

However, when I try to add my second input feature my code will not run

arcpy.CreateTin_3d(TIN_name, coordsys, outputFC + " Shape.Z masspoints" ; waterPoly + " Shape.Z softerase", Delaunay)

This is the code that I get when I export a script from ModelBuilder. However, these are hard coded shapefiles that

arcpy.CreateTin_3d(Output_TIN, "", "test Shape.Z masspoints <None>;test_3d_polys Shape.Z softerase <None>", "DELAUNAY")

This doesn't work either

arcpy.CreateTin_3d(TIN_name, coordsys, [outputFC + " Shape.Z masspoints"; waterPoly + " Shape.Z softerase"], Delaunay)

I was finally able to get this running.  My work around.....Create an empty TIN, then used "Edit TIN" which allows multiple input features.  This seems really silly since you can have multiple input features when using the create TIN tool in ArcToolbox. Maybe I was just doing something wrong with "Create TIN", so if you have a different solution I would love to know.

Hi Cotterrj,
try this.

spatial_reference = arcpy.SpatialReference(31466) # Zone 2

arcpy.CheckOutExtension("3D")
# input verzeichnis
env.workspace = r"C:\Temp"
# tin name
tin_name=r"test5"

fc1="abgrabungen01"
fc1_type = "Shape.Z"
fc1_sftype="masspoints"

arcpy.ddd.CreateTin(tin_name, spatial_reference,\
                        "{0} {1} {2};{3} {4} {5}"\
                       .format(fc1,fc1_type,fc1_sftype,"abgrabungen","Shape.Z","hardline"), "CONSTRAINED_DELAUNAY")

Best regards
Klaus
