Batch Meshing
# Generate 2D surface mesh and save
gmsh model.geo -2 -o output.msh
# Generate 3D volume mesh
gmsh model.geo -3 -o output.msh
# Specify output format
gmsh model.geo -2 -format msh22 -o output.msh
*See sub-skills for full details.*
## Format Conversion
```bash
# Convert MSH to STL
gmsh input.msh -o output.stl
# Convert STEP to mesh
gmsh input.step -2 -o output.msh
# Convert to MSH v2.2 (for BEM tools)
gmsh input.msh -format msh22 -o output.msh
# Convert with binary format
gmsh input.msh -bin -convert output.msh
