Standard Layers

Layer Organization Overview

00_CWKA-DWG (Drawing)

• Layout-specific layers & clipping layers. ¹
• Used in any phase.
• Includes: line weights, dimensions, notes.
• Primary Layers: ¹
  • Line weights (1, 3, 20, point, point 2, 4)
  • Dim and note layers (See Annotations)
  • Symbol tag (for blocks inserted in layout space)
  • Title block, revisions (changed only on special occasions)

01_CWKA-PRECON

• Intake models for estimation & modeling.
• Includes:
  • IN-2D: Plans, elevations, tabular data. ² Can include master plans imported from separate files.
  • IN-3D: Client models, point clouds. ² Can include laser scans, but not recommended to have laser scan in working file - not good practice for file performance.

02_CWKA-DE (Design Engineering)

• Converts approximate to precise geometry.
• Develops assembly details, SKs.
• Uses nominal dimensions.
• Layers:
  • CON: Guide geometry (not for printing).
  • PUR: Purchased raw materials (Epicor classes).

03_CWKA-FE (Fabrication Engineering)

Converts DE geometry to fabrication-ready models. This is where most FE work lives.

• CON — Construction geometry (guide curves, reference surfaces). Not for printing.
  • CON::CLIP — All clipping planes for layout section cuts live here. ¹
• PUR — Purchased materials, subdivided by Epicor material class: ³
  • FU (Fabric/Upholstery), GL (Glass), HW (Hardware), IM (Metal inventory), LE (Lighting/Electrical), SG (Sheet Goods), SL (Solid Lumber), SS (Solid Surface), ST (Stone)
  • Layer naming follows: [PartNumber] [Description] (matching Epicor)
• MFG — Manufactured parts (feeder jobs): ³
  • MT (Metal components)
  • WC (Wood components)
  • PRE (Pre-laminations — custom sheet goods)

04_CWKA-PE (Production Engineering)

Toolpaths, reference geometry, and fabrication programming info.

• REF — Reference geometry from FE including scribes, billets, guide curves, engraving geometry.
• MACHINING — Programming geometries generated by PE scripts. Uses specific naming conventions that encode the operation type, bit diameter, and depth:
  • THRU CUT OUT [thickness] — perimeter cuts (e.g., THRU CUT OUT 1.5)
  • THRU CUT IN [thickness] — cutouts (e.g., THRU CUT IN 1.5)
  • [bit diameter] POCKET [depth] — pockets, rabs, and dados (e.g., 1/2" POCKET 0.375)
  • [bit diameter] DRILL PT [depth] — drill points (e.g., 8MM DRILL PT 0.25)

Placeholder Layers

³ When starting modeling, you can create placeholder layers (e.g., “GM.SG.XXXXX shop ply 3/4”) as notes to yourself. Come back later and correct using toolkit to pull correct layer. This is a fast way to get started - get ideas down quickly, correct later. Obviously not releasable until corrected.
