FROM CAD MODEL TO GEANT

Simulation software Uses the GDML (geometry description markup language) Can split large geometry into smaller GDML modular files Doesn’t understand 3 D information used in STEP files GÉANT

STEP (Standard for the Exchange of Product model data) files are ubiquitous across multiple CAD software and used across multiple industries Major file formats: STEP AP 203: Defines geometry, topology, and configuration management data of solid models for mechanical parts & assemblies STEP AP 214: Includes STEP AP 203 features along with colors, layers, GD&T, and design intent STEP AP 242: Merges both STEP 203 & STEP 214 to introduce model-based definition (MBD) engineering Used between most CAD (computer-aided design), CAM (computer-aided manufacturing), CAI (computer-aided inspection), and CAE (computeraided engineering) software STEP

Standard Tessellation Language Used for rapid prototyping and computer-aided manufacturing 3 D printing – works with slicing software STL files contains the surface geometry of a 3 D object without information of color, texture, or materials Format can specify ASCII or binary representations Binary is more common due to being more compact ASCII contains more information STL

Describes 3 D geometry (the position of each vertex in a coordinate system) Mostly used in 3 D printing OBJ coordinates have no units, but OBJ files can contain scale information in a readable comment line Also works with some slicing and host softwares for 3 D printing Similar to STL files, the format contains geometry descriptions Can include materials, colors, and labels Can be higher resolution than STL files OBJ
