1 retained component records. These tables cover selected readable outlines, not the whole job. Mass and weight are gross estimates before sink and fixture deductions.
Upper source explicitly shows 22.5 depth, 11.75 step, 36.5 sink-center-to-right dimension and 3 cm thickness; full length absent.
Needs confirmation
68-inch full length and 24.5-inch step location are invented visual assumptions, clearly labeled; never treat as measured job data.
Upper 9.25 local dimension and sink location need clarification.
Upper TCE4047 and lower Y9006 are different jobs/materials and must never be merged.
Support review covers only the lower calculated strip and explicitly holds upper capacity checks.
The source images were visually reviewed; handwriting and field dimensions are not independently verified. Actual support positions and connection capacities are also unconfirmed.
Drag to orbit after opening the 3D model. Use + / − to zoom.
Visual scenario: 68 in overall length and 24.5 in step offset are estimates chosen for the model, not measured job dimensions. Sheet notes include 22.5 in depth, 11.75 in step and 30 mm thickness; the 9.25 in local note remains unresolved. No area or mass is assigned to this estimate. Surface finish is illustrative.
Assembly sketches join only faces supported by the drawing. Other pieces are grouped as sets. These are reconstructed schematics, not AutoCAD exports.

This is the missing upper countertop. The 68-inch length and 24½-inch step offset make a visual draft; they have not been measured. The local 9¼-inch note and sink position need clarification. Area, mass and weight remain unassigned. The lower Y9006 strip remains a separate material group.
Sink and backsplash notes
Nominal sink template: 17¾ × 11¾ in, radius reading 1 in; actual cutout and position unconfirmed. Backsplash note: 3¼ in high, full length unconfirmed. Neither becomes an additional stone part.

Thickness and density used in this table
Separate lower job: notched Y9006 strip: 20 mm drawing reading; density unassigned in this fixed record.
Per-piece gross estimates. Sink and fixture openings are not deducted. Blank results need missing inputs; support examples may use separate, labeled assumptions.
Lower drawing: a Y9006 strip at 20 mm thickness, recorded as its own material group. The upper TCE4047 drawing has an incomplete outline.
Measurements & calculation steps
Separate lower job: notched Y9006 strip
length: 18.625 in · height: 5 in · upper Right Notch Width: 1 in · upper Right Notch Depth: 1 in
A = 92.125 in² (rectangle addition) × 0.0254² = 0.0594 m² V = A × 0.02 = 0.00119 m³ Mass and weight need the missing inputs listed above; a blank is not zero.
Separate physical job below divider; material Y9006 and 2 cm explicitly written. Included in all-visible inventory under its own material, not merged with upper TCE4047 job. Corner 1 x 1 notch is an outer-profile subtraction.
The 1 × 1 in edge notch is already removed from this outside polygon; do not subtract it twice.
WHY THE CALCULATIONS MATTER
Understand the material before planning the job.
Area and thickness determine stone volume. Density turns that into an estimated mass, and gravity gives its weight. These quantities support planning and discussion with the family business; supports, handling and installation need fabricator or qualified professional review.
Area → volume
A = L × D, or add rectangle areas V = A × t 1 in = 0.0254 m
Table results are per component; quantity is shown separately. Sink and fitting templates remain notes until confirmed. Grouping does not combine different rooms or alternative sheet versions into one slab.
Volume → mass → weight
m = ρV Fg = mg g = 9.81 m/s²
Mass uses kilograms and weight uses newtons. A blank result means thickness or density is unconfirmed. Density assumptions and provisional readings remain identified in the calculation notes.
