# Local CDSL Engine
|
||||
|
||||
This package rebuilds `cad.cdsl.llm.v1` models through the CDSL-only path:
|
||||
|
||||
`sketch_solver -> llm_compiler -> llm_engine -> STEP`
|
||||
|
||||
Supported profiles are defined by `SHAPE_GENERATORS` in `sketch_solver.py`.
|
||||
The Studio only accepts self-contained profile data and requires successful
|
||||
`engine=cdsl_only` output. It never uses the legacy translator fallback or
|
||||
`compiler_context`.
