MASTERPIECE Facade System Grasshopper C# STEP Pipeline — Wickerson Studios

MASTERPIECE Facade System (Grasshopper C# STEP Pipeline) — Wickerson Studios + verison 2.0

COGENT Facade System is a stateful, STEP-based Grasshopper C# pipeline that builds an export-ready façade assembly from massing—fast. It’s designed like a “parametric machine”: each STEP takes in geometry + a cfg_override string, writes logs, and hands a STATE_OUT JSON forward so the entire system stays stable and tunable.

You get a clean, modular workflow for generating:

• Facade guide curves (contour bands or face-edge loops)
• Fins (attached to host Breps, outward-normal aware)
• Panels (lofted between facade levels, with optional thickness)
• Mullions (pipes / connectors between levels)
• Perforation cutters (structured grids with jitter/inset controls)
• Robust booleans (batched + bbox filtering + one-by-one fallback)
• Export-ready Breps + optional Meshes for fabrication / viz / BIM handoff
• Logging + caps + fail-safe behavior so large runs don’t explode

Why it’s different

Most GH façade scripts die when geometry gets real. COGENT is built to survive:

• Stateful pipeline: STATE_IN → STATE_OUT keeps settings and logs coherent across nodes.
• RhinoCommon-safe methods: avoids fragile overloads; uses face-based closest-point + normals where needed.
• Hard caps everywhere: max fins, max cutters, max boolean ops, per-target caps—so you can scale safely.
• Failure-safe booleans: batch → fallback one-by-one → skip + log (instead of crashing your definition).

What you actually run

A typical “production-ish” chain looks like:

• STEP_04 (FacadeCurves + Fins) from MassingBreps
• STEP_05 (Panels + Mullions + optional PerforationCutters)
• STEP_06 (Boolean difference on panels, batched + filtered)
• STEP_07 (Facade System Builder: mullions + louvers + cutters in face-local outward frames)
• STEP_08 (Finalize: robust boolean difference + optional mesh output)
• STEP_09 (Packaging: bake/layers + export + manifest) (optional if you want deliverables fast)

Ideal for

• architects + computational designers building façade studies at speed
• educators teaching a clean STEP pipeline with logging + state
• anyone selling/packaging parametric tools that must be stable under pressure
