 about=QGIS plugin for loading geophysical inversion mdels. Adds a menu item to the "Plugin" menu. The models are loaded as 3D points for the terrain surface with line numbers as labels, 3D points for DOI at depth, and model layers as 3D lines. The plugin supports profile visualization using the "Elevation Profile" tool in QGIS.
