STL-G 1 BRL-CAD BRL-CAD User Commands
stl-g Stereolithography Translator (STL to BRL-CAD)
`stl-g` -db -i initial_ident -I constant_ident -m material_code -N forced_name -c units -t tolerance -x RT_DEBUG_FLAG file.stl file.g

## DESCRIPTION

`stl-g` converts the specified file.stl to a BRL-CAD file.g file. Use the `-b` option if you have a binary STL file (the default is ASCII). The `-d` option prints debugging information. The `-c` option specifies the units that are used in the STL file. The units string may be "mm", "in", "ft", ... (default is "mm"). The `-t` option specifies a tolerance distance (in mm) such that any two vertices within tolerance distance of each other are treated as the same vertex. The `-i` option sets the starting ident number for the regions created. As each new region is created, this number will be incremented before assigning the next ident number (conflicts with `-I` ). The `-I` option sets a constant ident number that will be assigned to all the regions created (conflicts with `-i` ). The `-m` option sets a material code that will be assigned to all the regions created (default is 1). The `-N` option sets a name for the resulting BRL-CAD object. STL files typically do not contain any object names. The `-x` option sets an RT debug flag (see raytrace.h). The file.stl file is expected to be a stereolithography file.

## EXAMPLE
