How to avoid spline to start from origin in cadquery script

Dear all,

I am working on some tubular structures in which I am using splines and sweep to create the path of points.

But, the points does not start from origin but from different (x, y) coordinates. When I give spline to those points, the spline does well but it creates a closure by reaching to origin. How do I avoid that.?

Example:

In the below example, I want the spline to start from (1, 2), but it starts from (0,0). How to remove the spline from origin?

```
import cadquery as cq
from Helpers import show
Points we will use to create spline and polyline paths to sweep over

pts = [(1, 2), (2, 1), (4, -1)]
Spline path for points

path = cq.Workplane("XZ").spline(pts)

show(path)
```

I have attached the image link for reference.

Any leads will be appreciated.

Thanks and Regards,
