CAD to BIM Services
Optimar Precon provides CAD to BIM Services for architects, engineers, contractors and project teams that need structured BIM models created from CAD drawings, PDFs, markups and legacy design information.
Share your CAD drawings, PDFs or project files for a BIM scope review.
What Is CAD to BIM Conversion?
CAD to BIM conversion transforms 2D CAD drawings or other project documentation into structured 3D BIM models. The resulting model can contain coordinated geometry, building elements and project information based on the required discipline, LOD and BIM standards.
DWG and DXF drawings, PDFs, markups, sketches, legacy CAD documentation and other approved project information supplied for model development.
CAD to BIM Services and Model Deliverables
Our CAD to BIM Services convert existing drawings and project information into structured BIM models based on the required discipline, model detail, project coordinates and delivery standards.
Convert Legacy Project Information Into Usable BIM Models
We review the supplied CAD files, PDFs, markups or sketches and develop the required architectural, structural or MEP BIM model. Model geometry, levels, coordinates, families and information requirements follow the agreed project scope.

Need a specific CAD to BIM output?
Share the source drawings, required discipline, BIM standards, model detail, software version and expected deliverables so the conversion scope can be defined before modelling begins.
How Our CAD to BIM Conversion Process Works
We use a structured workflow to convert supplied drawings into BIM models while maintaining project coordinates, model requirements, agreed detail and quality-control checkpoints.
Define the Source Information and Required BIM Output
The conversion scope should establish which drawings form the approved source, the required discipline, model coordinates, software version, LOD or model detail and expected deliverables.
Review Source Files
Review CAD drawings, PDFs, markups and available project information to confirm the conversion scope.
Set Up the BIM Model
Establish levels, grids, coordinates, disciplines, templates and other agreed model settings.
Develop the BIM Model
Model the required architectural, structural or MEP elements from the approved source information.
QA and Deliver
Review geometry, model organisation and agreed requirements before issuing the final BIM files.
Your CAD source stays traceable through the conversion workflow.
Model development follows the approved source information and agreed BIM requirements rather than adding unverified design assumptions.

What Defines a CAD to BIM Model?
CAD to BIM is not simply a redraw of 2D geometry. Before modelling starts, the required discipline, model detail, coordinates, software environment, family requirements and final deliverables should be clearly established.
CAD to BIM conversion translates the supplied design information into the agreed BIM environment. It does not transfer design responsibility or replace decisions made by the responsible project design team.

Where CAD to BIM Adds Value Across a Project
CAD to BIM conversion can help teams move existing drawing information into model-based workflows for coordination, renovation planning, documentation, visualization and construction-stage BIM use.
Legacy CAD Drawing Conversion
Convert existing DWG, DXF and legacy project drawings into structured BIM models when teams need to move from drawing-based information to a modern BIM environment.
Legacy CAD → BIMRenovation & Existing-Building Modeling
Use available CAD drawings, PDFs, markups and approved existing-condition information to develop BIM models that support renovation and alteration planning.
Existing ConditionsMultidiscipline BIM Coordination
Bring architectural, structural and MEP information into compatible BIM models that can support multidisciplinary model review and coordination workflows.
CoordinationAs-Built BIM Development
Develop or update BIM models from approved record drawings, verified markups and supplied project information for agreed as-built BIM deliverables.
Record InformationModel-Based Design Review
Convert approved drawing information into a 3D environment that can make geometry, spatial relationships and model interfaces easier for project teams to review.
VisualizationConstruction Coordination Support
Prepare structured BIM models that can feed agreed downstream coordination, clash-review and construction-planning workflows where required by the project.
Construction BIMThe Value Comes From the Structured BIM Environment
A CAD to BIM project should create more than a visually similar 3D model. The agreed model structure should support the intended project workflow and required downstream use.

CAD to BIM Services FAQs
Quick answers about source file formats, Revit conversion, BIM model development and CAD-based BIM deliverables.
What is CAD to BIM conversion?
CAD to BIM conversion transforms approved 2D CAD drawings and other project information into structured BIM models. The model can include defined building elements, levels, coordinates, families and project information according to the agreed discipline, model detail and BIM requirements.
Can AutoCAD drawings be converted into Revit BIM models?
Yes. DWG and DXF drawings can be used as source information for developing Revit BIM models. The model structure, discipline, coordinates and required level of detail follow the agreed project scope.
What file formats can be used for CAD to BIM services?
CAD to BIM projects can use DWG, DXF, PDF, scanned drawings, markups, sketches and other approved project documentation. The available source information should contain enough detail to support the required BIM output.
Can architectural, structural and MEP CAD drawings be converted to BIM?
Yes. Architectural, structural and MEP CAD drawings can be converted into discipline-specific BIM models. Model development follows the approved source information and agreed BIM scope without transferring design responsibility from the responsible project design team.
What LOD can be developed from CAD drawings?
The required LOD or model detail should be defined for each project. The achievable model content depends on the quality and completeness of the supplied drawings, required discipline, family requirements and intended BIM use.
Can you create Revit families from CAD drawings?
Yes. Where required by the project scope, CAD component information can be used to develop Revit families with the geometry, parameters and level of detail defined for the BIM deliverable.
Can PDFs, scanned drawings and legacy drawings be converted into BIM?
Yes. PDFs, scans and legacy drawings can support BIM model development where the source information is sufficiently clear and complete. Missing, conflicting or unclear information should be identified and clarified before it is incorporated into the final model.
How are CAD to BIM project cost and delivery time determined?
Cost and delivery time depend on the number and quality of source drawings, project disciplines, required model detail, Revit family requirements, coordination scope and final deliverables. Reviewing the source files first allows the CAD to BIM scope to be defined more accurately.
