+"""Geometry processing and analysis
+
+IFC may define geometry explicitly (such as meshes) or implicitly (such as
+parametric extrusions). This module provides methods to extract geometric
+definitions in IFC into explicitly tessellated triangles or OpenCASCADE Breps
+for further processing.
+
+This is typically needed when writing software to visualise or analyse
+geometry. See also :mod:`ifcopenshell.util.shape` for deriving quantities.
