"""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.
