Rhino 3D Tip: Elefront: Attribute-Driven Naming and Scalable Bake Workflows

Elefront supercharges Grasshopper by making object attributes first-class citizens. Use it to name, layer, tag, and update geometry at scale—without manual baking.

Quick setup:

• Install via Rhino’s PackageManager (type “PackageManager” and search “Elefront”).
• Restart Rhino/Grasshopper after install; keep versions of Rhino, Grasshopper, and Elefront aligned.
• For Rhino licensing and pro add-ons, explore NOVEDGE and their Rhino catalog: search Rhino at NOVEDGE.

Core workflow pattern:

• Reference: Use Elefront’s “Reference by Layer/Name” (or a pipeline) to pull Rhino geometry into Grasshopper without duplicating it.
• Attributes: Build a clean attribute schema with keys like PartNumber, Material, Finish, Thickness, Process, and Revision. Use Elefront “Create Attributes” to assemble key–value pairs, plus Layer, Color, Linetype, and PrintWidth.
• Deterministic names: Generate a unique Bake Name (e.g., BRKT_A_001_R02) to enable reliable replace/updates.
• Bake: Use “Bake” with Name + Overwrite/Replace to update existing objects instead of creating duplicates. Direct output to structured layers (e.g., 03_Fab/Aluminum/3mm) to auto-create and keep hierarchy clean.
• Blocks: With “Create Block Definition” + “Place Block,” push parametric assemblies to Blocks that carry attributes to instances. Re-bake to update all placements.
• Read-back: “Deconstruct Attributes” lets you query geometry in Rhino and retrieve metadata for QA, schedules, or export.

Best practices for robust, data-rich models:

• Attribute hygiene: Use consistent, lowercase or camelCase keys (no spaces). Standardize values (e.g., “Al6061-T6” vs “6061”).
• Naming: Encode intent in Bake Names—include type, ID, and revision for traceability.
• Data Trees: Align tree structure with your geometry lists before baking. Use Graft/Simplify/Trim Tree to keep per-part attributes synced.
• Worksessions: Bake heavy outputs into an external 3DM and reference it into a master file. This keeps the main model light and collaboration-friendly.
• Performance: Disable solver while editing attributes, turn off previews for heavy components, and bake in batches. Avoid baking on every slider move.
• QA checks: In Rhino, verify User Text via Properties. Use SelName/SelLayer to find expected results. Run Check/Audit3dm periodically.
• Downstream: For BOMs, aggregate attribute tables in Grasshopper and export CSV with a lightweight script or a simple data export workflow.

Mini example:

• Reference sheet-metal profiles by layer.
• Generate bends/offsets in Grasshopper.
• Create Attributes: PartNumber=BRKT_A_001, Material=Al6061-T6, Finish=AnodizedBlack, Thickness=3.0mm, Revision=R02.
• Bake to 03_Fab/Aluminum/3mm with Name=BRKT_A_001_R02 and Replace=True.
• Place as Blocks for assemblies; re-bake to propagate changes.

Why Elefront for teams:

• Consistency: Everyone bakes to the same layers, names, and keys.
• Traceability: Attributes make BOMs, CAM prep, and QA auditable.
• Non-destructive: Update without manual cleanup or duplicate clutter.
