 **How do I choose a spatial resolution for my simulation?**
 Spatial resolution should be chosen to mitigate numerical dispersion and to adequately resolve geometry in your simulation. :ref:`A 2D example of modelling a metal cylinder in a dielectric <example-2D-Ascan>` provides guidance on how to determine spatial resolution.

+**I specified a certain piece of geometry but I don’t see it when I view my geometry file.**
 gprMax builds objects in a model in the order the objects were specified in the input file, using a layered canvas approach. This means, for example, a cylinder object which comes after a box object in the input file will overwrite the properties of the box object at any locations where they overlap. This approach allows complex geometries to be created using basic object building blocks.
