+This plugin makes use of CadQuery tags to collect surfaces into [Gmsh](https://gmsh.info/) physical groups. The
 tagged faces are matched to their corresponding surfaces in the mesh via their position in the CadQuery solid(s) vs the Gmsh surface ID. There are a few challenges with mapping tags to surfaces to be aware of.
 
 1. Each tag can select multiple faces/surfaces at once, and this has to be accounted for when mapping tags to surfaces.

 * [smoke_test.py](tests/smoke_test.py) runs two tests currently. The first is for a simple cross-section of a coil (image below), which makes it easier to verify basic operation. The second is for a planar coil, which forces the use of more advanced selectors, but is not as complex as a coil with a non-planar sweep path. This planar-coil test is not complete yet.
 
 Once the test has been run (using the pytest command), two mesh files (.msh extension) be created in the root of the repository.
