In select mode, drag empty space to pan; click an edge to edit its treatment. Switch to 2D to edit. Undo covers drawing edits; changes in other forms reset that history.

Estimate & manufacturing checks

This is a draft definition. Review the outstanding shop confirmations below. Exporting a file does not submit an order or reserve production time.

Planning estimate · assumptions

Import a drawing

Import a panel or a mating part. Assign profiles before changing the panel. Reference profiles are temporary overlays, excluded from the quote.

CAD file · ASCII DXF

DWG: export an ASCII DXF from your CAD application first. Supported: XY closed straight polylines, circles (64-segment approximation) and points. Explode blocks and join linework in CAD. Arcs, bulges, splines, meshes and open paths are reported, not silently converted.

Imported insert defaults

Circle/point centers locate inserts. Drawing hole diameter does not determine the insert pocket.

Units, placement and omitted entities reviewed Validate & apply selected geometryClear overlay

Applying replaces only the selected outer boundary (clearing old edge assignments), appends cutouts/inserts, and checks the complete panel before saving. Existing features remain.

Penetrations

Add cutout

Laminate & process

Rows are ordered from each exterior face toward the core. All angles reference the same global XY frame seen from A. A solid panel uses one full schedule from A to the back surface.

Laminate design assistant

Start with a repeated [ +φ / −φ / +ψ / −ψ ] UD block. Adjust two angles and the repeat count, then apply the actual ply list below. The generator retains exterior/core-side isolation; interleaved isolation needs explicit editing. Properties are provisional base-skin CLT estimates, not supplier-tested allowables or a homogenization/strength check.

Apply to face A B UD reinforcement φ (degrees) ψ (degrees) Four-ply block repeats

Append reversed sequence for explicit skin symmetry (doubles the plies) Apply double-double schedule

UD double-double and woven cloth rotated to the same angles are different laminates. Thin plies, repetition and actual coupling matter. Mirroring is optional; no automatic “no warp” claim.

Isolation and surfacing plies

Candidate material Exterior face A B Physical ply count

Add exterior isolation ply

Added as the first physical ply in that face schedule, included in mass/thickness/BOM and the 100-ply cap. It can be moved with the ply editor. Linked A adds the same ply to B. For prepreg, use an identified compatible glass prepreg; a dry veil is not silently co-cured without resin. Peel ply is removable process fabric, not a permanent electrical barrier.

Face A

Add ply group Use identical schedule on B

Identical face rows are not the same as a symmetric individual laminate. Symmetry is checked separately. Maximum 100 physical plies per face, including overlapping local additions.

Face B

Add ply group

Surface finish & tool side

A/B are fixed geometric face IDs. Select which face is on the mold without renaming faces or moving any insert, local region or edge assignment.

Apply surface preferences

Molded/tool finish is allowed only on the selected tool side; two molded sides need matched-tool review. Molded does not guarantee Class-A gloss. A single-sided edge taper initially targets the selected tool side; existing edges never change automatically.

Peel ply left on protects the process surface until removed. Peel ply removed leaves texture. Sanded means a controlled preparation request, not a guarantee of bond strength: confirm grade, release contamination, cleaning, abrasive/process and isolation-fiber protection.

Why peel-ply bonding preparation needs qualification

Hardpoints & local laminate

Placement is in global XY millimeters. Pockets and transition footprints must clear edges, cutouts and one another. Threaded insert hardware and G10 stock require sourced costs.

Per-edge treatments

Edge indices follow the submitted polygon vertex order, starting at 0. Select an edge in the plan or enter its index. Cutout edges are also selectable.

Assign treatment

Angles reference the panel plane. A/B means the core-facing plane of that skin, not the exterior surface. Tape is covering only, not a structural closeout. Exact tape adhesive compatibility is unverified.

V pan-down has no solid border and retains the face laminates as a finite tip centered on total panel thickness. A true zero-thickness knife edge would require cutting fibers and is not this operation.

Same-build companion coupons

“NIRSpec” is interpreted as NIAR-style testing. This tool proposes manufacturing blanks; the lab must approve the actual method, fixture, dimensions and preparation. Lab testing is not included.

Add draft tensile / compression / bending groups Apply coupon layout

Draft dimensions are editable allowances, not asserted ASTM dimensions. D3039/D6641 are laminate methods, never assigned to full sandwich panels. C297 is flatwise tensile, C364 edgewise compression, C393 core shear by flexure. Flexural span uses the selected span/thickness ratio; dimensions must fit the derived span.
