# create_csys_3d

Create three-dimensional coordinate system.

origo : array

Origo of the coordinate system

direction_i : array

Point to define the basis vector from origo in direction i

direction_j : array

Point to define the basis vector from origo in direction j

name : str

String naming the coordinate system.

• create_csys_2d
• get_csys

direction_k is derived from direction_i and direction_j.

prj.create_csys_3d(origo = [0,0,0], direction_i= [0,np.sqrt(2)/2,np.sqrt(2)/2], direction_j=[1,0,0],name="csys_3D")
