Blender Eevee + Sketchup.

Thanks,
Internet is very slow for this site.
Maybe, Im using the wrong type of curve.
I need to make some line profiles for curved chairs like the
example shown here:


Is there such a thing as a bezier curve with mirror.
By mirror, I mean adjusting one side of the curve and the other half side
automatically follows the same curve.
Thanks,
The trees and bushes are from ngPlant.
Background trees had leafs to large and changed
the trees.
