Thunderhead Engineering PyroSim

PyroSim imports AutoCAD DXF and DWG files. When PyroSim imports a DWG/DXF file, it will treat all 3D face data as obstructions and other data (lines, curves, etc.) as separate CAD data. The left image of the figure shows the DWG file face data, and the right image shows the grid representation that It will use in the FDS analysis.
