I would like to introduce you to the Simple Instanced Spline Mesh plugin.
The plugin provides a simple, lightweight, and robust tool for building Hierarchical Instanced of Static Meshes using splines.
It was built with level design in mind, to make designers' life easier, and iterations faster.
It offers a variety of tools related to meshes placed using spline.
