# STEP Parser — Phase 0 CLI container
|

#
|
|
# Goal: prove the heavy native stack runs on linux/amd64 (Unraid target):
|
|
# - CAD kernel build123d → cadquery-ocp (OpenCASCADE)
|
|
# - offscreen render pyrender via OSMesa (software GL, no GPU needed)
|
|
# - diagram export cairosvg (cairo / pango)
|
|
#
|
|
# Build for Unraid (x86_64) even from an arm64 Mac (uses QEMU emulation):
|
|
# docker buildx build --platform linux/amd64 -t step-parser:dev --load .
|
|
# or just: ./build.sh (build.sh passes --platform linux/amd64)
