3dsolid2fdsExternal Link ( AutoCAD ) - J. Dimyadi

3dsolid2fds is a software utility add-on for use in AutoCAD environment to easily and quickly convert the geometry of 3DSOLID objects to the formatted &OBST lines for FDS.
Where objects are constructed on separate layers such as walls, doors, furnitures, etc., 3dsolid2fds would pick up the layer name and use it as SURF_ID on each &OBST line. This is handy for later material specification in the FDS input file.
