Feature

Feature represents a higher-level characteristic identified on the drawing, such as a hole, slot, or surface that carries additional requirements. The model serves as a hub linking geometry, dimensions, tolerances, and manufacturing instructions for that feature. It stores classification tags, references to the source view, and relationships to parent or child features, enabling you to reconstruct the feature tree programmatically. Downstream consumers can use it to group related annotations, determine machining intent, or assess which features drive inspection plans. Because many workflows revolve around features rather than isolated dimensions, this object provides the context needed to map extracted data to CAD models, process plans, or quality checkpoints.
