This app was developed for the purpose of easily generating clean geometries on a regular grid pattern.  Survey files (dxf, dtm) are used as input geometry to the app.  The specified volume is discretised into a regular grid of cubic cells. The algorithm detects which cells are inside and outside excavations and which cells are being cut by the boundaries of excavations.  The models can be directly exported in different formats for use in mXrap apps or other software, such as numerical modelling packages. Map3D .inp files and FLAC3D grid files can be generated directly, allowing for mine-scale models to be built and ported to numerical modelling packages in a matter of minutes.
