IfcTruss

Create and calculate trusses in IFC’s

Purpose

IfcTruss is an open source (LGPL-3.0-or-later) software library for creating and calculating trusses in the Industry Foundation Classes (IFC) standard. More precisely, the IFC 4.3 version is supported. This version is an ISO standard.

The following main functions are provided for building, viewing and solving a truss model in IFC:

ifctruss.build
ifctruss.view
ifctruss.solve

There are also a few additional side functions that can be used:

ifctruss.save_ods_template
ifctruss.save_xlsx_template
ifctruss.build_from_ods
ifctruss.build_from_xlsx
ifctruss.save_result

Two solvers are available for calculating the trusses. These solvers can also be used below without IFC:

ifctruss.solver.direct_stiffness_method
ifctruss.solver.calfem

Go to the Getting Started page to learn more about using this library.
