Netral is a former French company that once developed and sold a range of modeling-related software such as NeuroOne, NeuroShop and others. Models created by those software use a in-house XML format called NML.
The ShapeKit Suite can interact with those software. The ShapeKit Exploiter can import and export models from and to the NML file format.
The import feature allows to read a NML file as if it was a Design file, and then all features from ShapeKit Exploiter can be used: tests, code generation and spreadsheet export.
The export menu entry converts the Design currently loaded to a NML file. This is especially useful if you want to perform some tests on a Design file using the legacy software you are used to.
