Tables

Objects can be added, deleted and retrieved from a Model using tables.

All tables implement an iterator, add and getter methods and they allow working on small subsets of objects (Curves, Points, …). All the tables that refer to geometrical objects are an interface to the same container via ON_ModelComponent::Type::ModelGeometry.

LayerTable

The LayerTable class provides interface to objects of type ON_ModelComponent::Type::Layer.

Despite these objects are supposed to be accessed (and actually are) by ON_UUID (or index) like any other objects in Model, this table provides abstractions to enable access to Layers via full name, i.e., using the format parent::leaf.

It is highlighted that deleting the last Layer in the table and adding a new one does not guarantee nor preserve the order of the Layers in the table in case of deletions and additions.

CurveTable

The CurveTable class provides methods to add .

PointTable

The PointTable class provides methods to access and modify existing ON_Point s as well as add new ones.
