Help: Maya 2018 script poly projection error

[Anonymous]

Hi guys i got this script for maya:

polyProjection -type Planar -md p;
polyUVHardEdgesAutoSeams 1;
u3dLayout -res 256 -box 0 1 0 1;

what its basically does its unfold the object after selecting which edges are hard and which swift and it will unfold it on the uv editor layout , my friend use it for maya windows , but i wanna use that script on maya on the Mac osx , but the problem with the script telling me : // Error: line 3: Cannot find procedure "u3dLayout".

does this script wont work on Mac ?

sorry for my english and thanks in advance !

Go into the Plug-in Manager and make sure the plugin "Unfold3D" is loaded.
