ModelValidator

class pyslm.geometry.ModelValidator

Bases: object

ModelValidator takes the pyslm.geometry data structures such as a list of Layer and Model and validates their input for consistency when utilised together to form a build file prior to exporting using libSLM. Basic checks include:

• Validating each BuildStyle used in each Model, including individual laser parameters

• References to a correct BuildStyle via its id (bid) for each LayerGeometry section

• References to a correct Model via its id (mid) for each LayerGeometry section

• Ensure there are unique BuildStyle entries for each Model

The key function that can be called is validateBuild() which ideally should be called before attempting to export the layer and model information to a libSLM Machine Build file translator. Additional sub-functions are also available for checking specific objects used to construct the build-file.

Methods Summary

validateBuild(models, layers)	Validates an AM Build which compromises of a list of models and layers
validateBuildStyle(bstyle)	Validates a single BuildStyle ensuring that its individual parameters are not malformed.
validateModel(model)	Validates a single Model ensuring that its individual BuildStyles are not malformed.

Methods Documentation
