What we do
Rockall Projects produces 2D CAD and 3D models from point clouds to support design development, coordination, fabrication interfaces, and reliable record information.
Where Scan to BIM is focused on structured BIM outputs, point cloud to CAD is often the most efficient route when teams need clear drawings and pragmatic geometry for planning, coordination, construction, or documentation.
We work from:
- point clouds captured by us (3D laser scanning), or
- client-supplied point clouds (subject to suitability review).
Typical uses
Point cloud to CAD / 3D modelling is most useful when you need dependable geometry without over-complicating the deliverable:
- Refurbishment planning and design development where record drawings are unreliable
- Coordination between trades, interfaces and tight spaces
- Drawing production: plans, sections, elevations, reflected ceiling plans
- Verification of key dimensions and interfaces
- Fabrication interfaces where pragmatic 3D geometry is required for setting out and coordination
- Record documentation at handover
Deliverables
We agree scope and outputs upfront so the deliverables match the downstream use.
Common deliverables include:
- 2D CAD drawings (DWG/PDF)
Plans, elevations, sections, RCPs and schedules as agreed - 3D CAD model
Typically in formats aligned to your workflow (DWG, IFC, STEP/IGES where appropriate, or other agreed formats) - Model/drawing conventions
Layering, naming, and structuring aligned to your standards where provided - Point cloud deliverables
Packaged in agreed formats (E57, RCP/RCS etc.) with clear segmentation
If you’re unsure whether you need 2D, 3D, or BIM outputs, we’ll recommend the simplest deliverable that achieves the project outcome.
Scope and tolerances (what gets modelled)
This is where point cloud modelling succeeds or fails: we define what is included, to what precision, and for what purpose.
We typically define:
- included elements (architectural / structural / MEP / targeted zones only)
- drawing/model extents and boundaries
- tolerance expectations (fit-for-purpose)
- how to handle ambiguous/hidden items (voids, boxed-in services, behind ceilings)
- any no-access / no-visibility constraints
This keeps cost, programme and expectations aligned.
Our process
- Brief and scope definition
Intended use, outputs, areas, tolerances, standards and programme. - Point cloud assessment
We either capture the data or review client-supplied point clouds for completeness. - Preparation and segmentation
Structuring the dataset so modelling is efficient and navigation is easy. - CAD / 3D modelling
Drawings and models produced to the agreed scope and conventions. - QA and validation
Checks against the point cloud and review of critical areas/interfaces. - Delivery
Packaged outputs with a short handover note covering scope and assumptions.
FAQs
Do we need Scan to BIM, or is CAD enough?
If you need a structured BIM model for coordination and downstream BIM workflows, Scan to BIM is likely best. If you need reliable drawings and pragmatic geometry quickly, point cloud to CAD is often the most efficient approach.
What do you need from us to quote?
- building/site address (if capture is required)
- areas and scope (what needs drawing/modelling)
- required outputs (DWG/PDF/3D formats)
- intended use (refurb/tender/coordination/verification)
- programme dates and any access constraints
- any layering/naming standards
Can you work from our point cloud?
Often yes, subject to quality and coverage. We’ll confirm suitability before committing.
Can you model MEP?
Yes, but MEP scope should be defined carefully (targeted high-risk zones vs full detail). We’ll recommend a pragmatic approach based on the project need.
