Countertop cutouts, seams and fabrication geometry
Revised Every Edge Is A Piece (v3, the cut to post): longer holds on the piece tags, no doubled legs mid-fold, and a nest layout where every strip sits beside its parent piece.
THE WORKFLOW IN ACTIONSLABOS · 27 SEC
Every Edge Is A Piece v3Watch the workflow. Put it to work in your shop.
Fixture openings and slab seams affect both the appearance and fabrication plan. SlabOS records cutouts in the countertop drawing and supports seams that divide the work into pieces for layout. CAD and nesting pages explain the adjacent workflows: the same design must make sense as geometry and as material use.
Inputs this workflow uses
Countertop geometry, fixture opening dimensions and proposed seam positions.
Outputs to evaluate
Drawing pieces and slab layouts that reflect the chosen openings and seams.
A representative demonstration
Show a sink opening and seam on the drawing, then identify the resulting pieces in the slab layout.
Bring a representative job to a SlabOS demo and see how this capability fits your shop’s work.
Scope and availability
Fixture model dimensions and final fabrication approval remain necessary. An unpriced opening is not necessarily absent from the geometry.
A closer look at the decisions, details and handoffs that make the work happen.
47 And Three Eighths
Magnetic center snap in the SlabOS drawing engine: on an L, the sink snaps to the center of the inside edge (47⅜″), not the wall's middle (60⅛″), stored exactly and off the ¼″ grid; quarter points for double vanities, bump-outs centered on the sink, and Alt to place freely.
Drawing-editor teaser: an outlet dragged onto a backsplash snaps to 7 1/2 inches above the counter, copy and paste drops each copy 10 inches along the run, and round hole groups take 1 to 4 holes.
Fixtures from the drawing: every cutout on the quote drawing becomes a row sorted by area, the templater pins a bridge-faucet warning, and each row is confirmed by name before the saw.
Use Seam All Pieces to apply suggested seams to oversized pieces, run one auto-nest and undo the operation together. Pieces still too long are flagged for review.
