2D to 3D Conversion: From Drawings to Intelligent Models

We model your 2D plans, sections and part drawings as 3D Revit, SolidWorks, Inventor or SketchUp models – and report any conflicts the model reveals.

  • Fixed quote before we start
  • DWG, RVT & PDF delivery
  • US, UK, CA & AU standards

What 2D to 3D conversion gives you

Turning 2D into 3D is rarely a mechanical exercise. Plans, elevations and sections were drawn separately, so they often disagree on heights, wall thicknesses or hole positions. As we build the model, every disagreement surfaces. We log each one with the sheets involved and the value we used, so you can confirm instead of discovering it on site or in production.

For buildings, we model in Revit with real wall, floor, roof and family types to the level of detail you need – from LOD 200 massing for visualisation to LOD 300–350 for coordination and documentation. For products, we build parametric parts and assemblies with the tolerances and features in your drawings.

If your source is a PDF or paper drawing, we combine this with PDF to CAD conversion. For building models used in coordination, see BIM modeling services.

Deliverables you receive

  • 3D model in the target software (RVT, SLDPRT/SLDASM, IPT/IAM, SKP)
  • Model built to the agreed LOD or feature level
  • Discrepancy log of conflicts between the 2D drawings
  • New 2D sheets generated from the model (optional)
  • IFC, STEP or FBX exports
  • Quantities or BOM from the model

2D to 3D CAD Conversion standards in the USA, UK, Canada and Australia

We set up every project on the standard of the country where it will be built or manufactured. These are the references we work to most often:

CountryStandards and codes we draft 2D to 3D CAD conversion to
USABIMForum LOD Specification; ASME Y14.41 for model-based product definition
UKBS EN ISO 19650 and the UK BIM Framework; Uniclass 2015 classification in the model
CanadaCanBIM LOD and protocol documents
AustraliaNATSPEC National BIM Guide and object naming

How our 2D to 3D CAD conversion process works

  1. 1
    Send your files

    Upload sketches, PDFs, markups, photos, scans or a model through the quote form. Tell us the standard (US, UK, Canada or Australia) and the deadline.

  2. 2
    Fixed quote in hours

    We review the scope and reply with a fixed price, the deliverables list and a delivery date. Nothing starts until you approve it.

  3. 3
    Drafting & modeling

    Your project is drawn in AutoCAD, Revit, Civil 3D, SolidWorks or the software you use, on your title block, layers and templates.

  4. 4
    QA check

    A second drafter checks dimensions, annotations, layer standards, sheet numbering and cross-references against your input before anything is sent.

  5. 5
    Delivery & revisions

    You receive native files plus PDFs. Comments come back as markups and we revise them quickly until the set matches the brief.

Turnaround and pricing

A house or a simple part family converts in 2–4 business days; larger buildings are quoted by floor area and LOD. Every job is priced as a fixed quote after we review your files, so you know the cost and the delivery date before work starts. See how our pricing works, or send your files through the quote form for a quick estimate.

2D to 3D CAD Conversion projects often need 3D drafting services, BIM modeling services and PDF to CAD conversion as well. You can order them together on one quote, or browse every option in our design services.

Frequently asked questions

Can 2D drawings be converted to 3D automatically?

Not reliably. Software can extrude simple outlines, but walls, roofs, openings and features need to be modeled properly to be useful. We model manually using the 2D drawings as a guide.

Which software do you convert into?

Revit for buildings, SolidWorks or Inventor for mechanical parts, SketchUp for massing and visualisation, and AutoCAD 3D on request.

What happens if my plans and sections do not match?

We follow the rule you choose (for example, dimensions on plans win) and list every conflict in a discrepancy log for you to confirm.

Can you produce new drawings from the 3D model?

Yes. Once the model is done, we can generate a new, consistent 2D set from it.

What LOD do I need?

LOD 200 is enough for visualisation and massing; LOD 300 for documentation and quantities; LOD 350 or higher for detailed coordination.

Needed 2D to 3D CAD conversion urgently for a submission. They turned it around in 24 hours and kept us updated the whole time. Highly recommended.

SSophie B.Fabricator · Leeds, UK · 1 month ago
★★★★★

Clear pricing, clean drawings and quick revisions. Their 2D to 3D CAD conversion saved us a lot of evenings this quarter.

DDaniel K.Homeowner · Ontario, Canada · 3 months ago
★★★★★

Good communication across time zones – we send markups at night and wake up to updated sheets. Solid 2D to 3D CAD conversion at a fair price.

CChloe W.Design manager · Melbourne, Australia · 2 weeks ago
★★★★★

We outsourced our 2D to 3D CAD conversion to them for the first time and it was smooth from start to finish. Fixed quote in a few hours and files back before the deadline.

SSarah M.Interior designer · Texas, USA · 1 month ago
★★★★★

Very happy with the 2D to 3D CAD conversion. They followed our standards, asked the right questions instead of guessing, and the QA was obvious – almost nothing to correct.

EEmma L.Product designer · London, UK · 3 months ago
★★★★★

Third project with them now. For 2D to 3D CAD conversion they are faster than our in-house team and the native files open perfectly on our side.
