IX2D is an interactive 2-D gravity and magnetics forward modeling and inversion package based on polygonal models which can be truncated asymmetrically along strike. It is basically a port of MAGIX XL to Windows, complete with translation of MAGIX functionality to a true Windows interface.

Features Include:
    Real-time forward modeling while moving vertices, moving or rotating bodies.
    Inverse modeling with selected parameters.
    Control over free parameters.
    Locking together of vertices.
    User friendly prevention of illegal bodies.
    Hotkeys allow quick changes to graphics - show locks, free vertices or color fill.
    Toolbar buttons offer quick access to most-used functions.
    Virtually no limit on size of data or model.
    Automatic and user-specified labels.
    User-specified line colors.
    Annotated color fill for body parameters.
    Spreadsheet data editors with copy & paste.
    Spreadsheet model editors.
    Optional grid lines on display.
    ASCII File import and export of data, synthetics and models.
    Import of MAGIX Plus/MAGIX XL files.
