Write a text file using the commands show below and then open it with Assembly -> File.  

The file should follow this format:    

3d=True 

polyline=False 

1 0 0 

1 0 1 

1 1 0 

1 1 1   

The coordinates are defined as (Z, X, Y). Use as many lines as the number of points needed. Make sure that the units used are consistent.
