Feature is regarded as orthogonal when it is parallel to one of the axis (X, Y or Z-axis). However, a slight change in orientation causes orthogonal feature to be classified as non-orthogonal. In most 2D-feature recognition or even 3D domain, this slight change in orientation requires a totally different feature recognition method. Despite this, still orthogonality of the feature is considered trivial. In this chapter, a system that identifies orthogonal and nonorthogonal features from orthographic drawing is demonstrated. The system is two-level feature recognition; profile searching and feature completion. Profile searching identifies the orthogonal and non-orthogonal profiles using a multi-level top-down approach. This stage is in fact the heart of the system, which makes it able to recognize orthogonal and non-orthogonal profiles. Feature completion establishes the machining volumes emanating from the profiles.
