# DfAM Check Provenance: maintained in [earthtojake/text-to-cad](https://github.com/earthtojake/text-to-cad). Use the installed local skill files as the runtime source of truth; the repository link is only for provenance and release review. Use this skill to produce conservative, evidence-backed DfAM reports for mesh files before slicing or printing. It measures geometry facts locally and compares them against per-process design limits; it never slices, uploads, or starts print jobs. ## Geometry Inspection Use `scripts/dfam_tool.py` in the active project Python environment for all geometry facts (install `requirements.txt` first — every run needs it). The tool is fact-only: it reports measurements and never emits pass/fail or readiness statuses. Comparisons and verdicts belong to this workflow. Do not estimate wall thickness, overhang angles, or support volume by eye or from renders when the tool can measure them. ```bash python scripts/dfam_tool.py measure part.stl --angle-limit 45 python scripts/dfam_tool.py orientations part.stl --angle-limit 45 ``` Set `--angle-limit` to the target process's self-supporting angle from `references/process-limits.md` before measuring, and re-run when the target process changes: the aggregate support-area facts are binned against it. STEP/STP input is boundary-representation CAD, not a mesh. When the `$cad` skill is installed, export an STL sidecar with it first, then measure the STL here. Report that remediation instead of attempting...
