Modeling & Conversion

CAD to BIM Conversion

Precision BIM from legacy drawings — structured, classified, and ready for project use.

Overview

CAD to BIM Conversion

CAD to BIM conversion goes beyond tracing lines in 3D. We rebuild your legacy CAD assets as fully parametric, classified, and data-rich BIM models — optimised for the specific project use case, whether it is coordination, analysis, facilities management, or digital twin input.

Structured & Classified

Elements classified to Uniclass, OmniClass, or project-specific schemes from day one.

Use-Case Optimised

Conversion configured for coordination, FM, or analysis — not a generic one-size model.

Scalable Process

Systematic conversion workflow that handles hundreds of drawings consistently.

FAQ

Frequently Asked Questions

Common questions about our CAD to BIM Conversion service.

Our CAD to BIM Services focuses on project-use conversion — getting a working model for design coordination quickly. CAD to BIM Conversion is a structured bulk process optimised for large drawing sets with COBie, FM handover, and IFC outputs as primary deliverables.

Yes — we work with DWG, DXF, DGN, PDF, and scanned paper drawings. Format complexity affects cost and timeline, which we assess and price transparently during scoping.

Yes — for large conversion programmes we always run a pilot on one floor or area first. This validates the conversion rules, confirms LOD expectations, and gives both parties confidence before scaling up.

We export IFC 2x3 and IFC 4 depending on the receiving system requirements. IFC exports are tested in Solibri or Navisworks before delivery to confirm geometry, property sets, and classification data integrity.

Yes — converted models are QA-checked and properly categorised in Revit, so they can be federated immediately in Navisworks or ACC for multidisciplinary coordination. Model quality is verified before handover.

Drawing revisions during conversion are managed through a change log. Revised drawings are queued and processed at the next milestone checkpoint rather than ad-hoc, to maintain conversion consistency and avoid rework.

Yes — COBie data mapping is configured as part of the conversion setup. Asset data from drawing notes and schedules is populated into the BIM model and exported in COBie 2.4 format for FM system import.
