# create_csys_3d

Create three-dimensional coordinate system.

## Parameters

<dl>
<dt>origo : array</dt>
<dd>Origo of the coordinate system</dd>
<dt>direction_i : array</dt>
<dd>Point to define the basis vector from origo in direction i</dd>
<dt>direction_j : array</dt>
<dd>Point to define the basis vector from origo in direction j</dd>
<dt>name : str</dt>
<dd>String naming the coordinate system.</dd>
</dl>

## Notes

direction_k is derived from direction_i and direction_j.

## Examples

```python
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")
```
