MAGIC Build 3D graphical input builder

The widely-employed MAGIC finite difference electromagnetic particle-in-cell code (FDTD EM-PIC) tool suite [1] has been upgraded to include a graphical three-dimensional (3D) input builder, Build3D. The tool enables multiple views of complex geometries and their components. Input occurs via toolbars and menus, as well as from MAGIC- and SketchUp-generated input files. The Build3D code interfaces with the MAGIC Workbench, and writes output suitable for execution in MAGIC3D. It also exports to AutoCAD, and can display Dxf format CAD files.
