Material Thickness & Modeling
Solid Body Requirements
All parts must be closed, manifold polysurfaces. Before release, verify:
SelBadObjects— should return nothing (fix any found)SelOpenPolysrf— should return nothing (close any found)SelExtrusion— convert all withConvertExtrusion
See Model Cleanup Commands for the full pre-release sequence.
Modeled Thickness
- Most materials: Model at nominal thickness (3/4” = 0.75”, 1/2” = 0.5”, 1” = 1.0”)
- Metric-spec materials: Model at metric nominal (18mm plywood = 18mm)
- Exception — 3/4” plywood: Model at 0.73” (always thinner than nominal). This is the only standard deviation.
- Solid wood: Model at design thickness. BOM rough lumber at appropriate oversize (you cannot get a 1.0” part from 4/4 rough lumber; use at least 5/4).
Edgebanding Rules
Do NOT model edgebanding for straight, square edges — the edgebander’s pre-mill setting removes the EB thickness before application.
DO model edgebanding when:
- Post-lamination condition (PLAM/VEN applied after structure is built)
- All solid wood edgebanding
- Inside or outside curved edges
- Notches on edge of part
- Cutouts internal to a part
- Any edge that cannot be run through the edgebander
Painted MDF
Painted MDF with exposed edges needing paint requires paintable edgebanding (GM.SG.00311) to be BOM’d to the job. Model the EB only if the edge can’t go through the edgebander.
Material Size
Parts must fit within actual sheet dimensions, not nominal catalog sizes. See Actual Sheet Sizes for the complete reference.
| Material | Maximum Part Size |
|---|---|
| Veneer / Melamine | 48” x 96” |
| MDF / Particleboard | 48” x 96” |
| Plywood (standard) | 47.5” x 95.5” |
| Plywood (birch) | 47.5” x 95.5” |
Additional stock sizes (4x10, 4x12, 5x10, 5x12) are available. Seam a part if it exceeds your stock size.
Bent Metal
Model with correct inside bend radius and thickness. 2D flat patterns/unfolds must include appropriate bend deductions.
Groups and Shipping Components
Group polysurfaces into shipping components early. Name groups with SC designators (e.g., SC005). Multiples of like geometry can share one SC number; unlike loose parts cannot.
Blocks and Hardware
- Individual hardware pieces are blocks
- Higher-order assembly blocks nest individual hardware blocks
- Hardware blocks use bracketed hardware tags; manufactured linked blocks follow MFG part format
- The hardware block library is organized by Epicor ClassID categories
Referencing External Geometry
Use Insert → Linked → Layer Style: Active. Choose:
- Block Instance for fixed reference geometry
- Individual Objects for editable parts
Toggle off rotation, scale, and insertion point prompts to maintain coordinate system alignment.
