HeeksCAD is a CAD application. It can import solid models from STEP and IGES files, draw construction geometry and lines and arcs, create new primitive solids, or make solids by extruding a sketch or by making a lofted solid between sketches. Solids can be modified using blending or boolean operations. Models can be saved as IGES, STEP, and STL. The 2D geometry can be plotted with a printer or to HPGL. DXF files can be imported and exported; lines, arcs, spline, ellipses, and polylines are supported. SVG import has similar capabilities. It is possible to make Add-In modules. The HeeksCNC project provides a CAM add-in, and HeeksPython provides a Python console.
Invenio (formerly CDSware) is a suite of applications that provides the framework and tools for building and managing an autonomous digital library server. It complies with the Open Archives Initiative metadata harvesting protocol (OAI-PMH) and uses MARC 21 as its underlying bibliographic standard. Its flexibility and performance make it a comprehensive solution for the management of document repositories of moderate to large size.
