BIM / CAD Technical Modelling
Stone is one of the hardest materials to express accurately at drawing stage: complex profiles, thickness, cut-outs and nesting all need to be resolved in the model. Hengsheng provides parametric modelling in Revit, SketchUp and AutoCAD so the designer's model can drive nesting, embeds and cost planning directly.
Core Strengths
- Parametric modelling: modelled to real slab formats, thickness and fabrication methods, so model dimensions are orderable dimensions.
- Millimetre embeds: openings, rebates and embed positions reserved in advance, avoiding on-site cutting that damages stone.
- Nesting output: nesting and assembly drawings generated from the model, balancing yield against visual effect.
- Multi-format: works across Revit, SketchUp and AutoCAD for smooth design-to-site coordination.
Key Figures
Service Process
- Model intake: designer BIM/CAD model plus structural and MEP data.
- Process translation: model adjusted to real capabilities, marking machinable and non-machinable areas.
- Nesting optimisation: large-slab layout balancing veining direction and yield.
- Drawing issue: fabrication, nesting and embed drawings produced.
- Site verification: dimensions checked with the contractor before cutting.
Applications
- Design development and cost planning
- Curtain wall, vanity and complex-profile embeds
- Pre-construction drawing coordination
Sustainability & Certification
Accurate modelling reduces site cutting waste and rework, indirectly lowering material waste; manufacturing achieves >85% waste utilisation.
Model-based nesting uses material more efficiently, supporting ISO 14001 environmental management.
Deep Selection Guide
The value of stone modelling is turning "looks right on paper" into "orderable", and the gap usually sits in slab format and cut-outs. Model against real machinable formats and thickness, and mark openings, rebates and embeds explicitly; nest with both veining direction and yield in mind rather than an arrangement that looks good but wastes material. Verify dimensions with the contractor once the model is complete.
- Selection criteria：Select by application (interior/exterior floors, walls, vanities), abrasion and slip ratings and maintenance habits; confirm thickness and cut-out detailing.
- Specification & thickness：Select by application (interior/exterior floors, walls, vanities), abrasion and slip ratings and maintenance habits; confirm thickness and cut-out detailing.
- Acceptance & records：Every batch ships with test data and image records, traceable by batch code back to the quarry, with dimensional and gloss checks completed before dispatch.
- Sustainability：Single-batch locking reduces waste and offcuts are recycled; low-VOC options available for healthy interiors.
Hengsheng manages the full chain from quarry-direct sourcing, smart manufacturing, global delivery and on-site installation. The advantage lies not in a single product but in connecting selection, fabrication, QC and delivery into an auditable loop, giving project teams clear assurance on programme, quality and compliance.
FAQ
- Which formats are supported?
- Revit, SketchUp and AutoCAD.
- Can the model be used directly for ordering?
- Yes — model dimensions are the orderable fabrication dimensions.
