Help working with spline objects

I am trying to work out the centre point of a spline. However this has proven to be more difficult than first expected. I figured I would have to get the SplineCore and then calculate each point in the spline to work out the centre… However there doesn't seem to be a way to work with each point in a spline.

Can somebody please point me in the right direction?

Thanks
 
Looks like you can get the general shape from the SplineCore.cache()

However I have two troubles with this:

1. If your draw a spline from top view so that the y coordinate doesn't change from 0 then you loop through each Vec3D you will find most of the Vec3D's show the y coordinate with a value.

This value is a little weird in that it has a letter 'e' followed by a hyphen '-' followed by a number. e.g.

'x' => "-2.1767666339874268"
'y' => "1.2102125968027622e-9"
'z' => "-2.306105375289917

What does this mean!?

2. How would you make changes to the spline?
 
I think that means the 'Y' value isn't quite at zero. Move the decimal point 9 places to the left from 1.2... and you get something like .0000000012, a very small value, but still not zero.
 
hi

a function to delete point nor set point seems to be still missing, just create spline functions are available for now.

Best
