Modelling 2D geophysical section

[oyo-rdc]

Wondering how a 2D geophysical section can be modelled. It is a (sort of) 2D version of voxel data but the 2D panel can be curved as shown below.
It can probably be done using thin voxel models but needs to instantiate them for each column to represent a curved section in the case of the section along the z-direction. Or would it be possible to add another entity for this type of data??
