2D drawings · AutoCAD 3D models
"Do we need a 3D model?" is one of the first questions clients ask, and the honest answer is often no. Most permit drawings, site drawings and fabrication drawings in Dubai are still issued as 2D sheets, because that is what authorities review and what site teams build from. But there are jobs where a 3D model saves real time and money: a tight ceiling void, an awkward staircase, a joinery piece with compound angles, or a client who can't read a plan.
We produce 2D drawings and 3D models in AutoCAD for architects, designers, contractors, developers and fabricators in Dubai. We will tell you which format your project actually needs before you pay for it, and when we do build a model, we use it to produce the 2D sheets as well, so the two always agree.
| 2D drawings | 3D model | |
|---|---|---|
| Best for | Permit and NOC submissions, construction drawings, shop drawings, as-builts, most fit-outs | Coordination in congested areas, complex geometry, fabricated items, visualising a design |
| What you receive | Plans, elevations, sections and details as DWG and PDF sheets | An AutoCAD 3D model (DWG), plus 2D views, sections and images taken from it |
| Effort | Lower for a typical project | Higher; every element has to be modelled in all three dimensions |
| Typical users | Owners, contractors, consultants, authorities | Designers, MEP coordinators, fabricators, developers presenting a scheme |
| When it is the wrong choice | When a clash or a shape can't be understood from plans and sections | When the drawings are for a standard permit or simple layout change |
A simple rule: if everyone involved can understand the job from plans, sections and elevations, 2D is enough. If people keep sketching the same corner in three dimensions to explain it, a model is probably worth building.
The core of most projects: floor plans, elevations, sections, details, schedules and layouts for architecture, structure and MEP, drawn to scale with a clear layer structure, consistent dimensions and annotations, and a proper title block and revision table. Our discipline pages cover these in detail: architectural drafting, structural drafting and MEP drafting.
Many firms have drawings that open but are painful to use. We clean and rebuild existing DWG files so they are safe to edit:
Cleaned files are smaller, faster and much less likely to cause errors when other consultants reference them.
Massing and detailed models of villas, extensions, interiors and small buildings, used to check how a design works in three dimensions and to produce views for the client, the developer or the design team. Models are built from the architectural drawings, so levels, openings and dimensions match the 2D set.
Models of the structure and building services in congested areas, such as corridors, plant rooms, risers and ceiling voids, built from the architectural, structural and MEP drawings. They make clashes easy to see and explain, and the agreed solution is then drawn back into the coordinated 2D drawings. For most of a building, coordinated 2D plans and sections are sufficient; we model the areas that need it.
Joinery units, metalwork, staircases, balustrades, display units and other fabricated items modelled in 3D, so that shapes, joints and fixings can be checked before manufacture and 2D fabrication drawings can be taken directly from the model. See also our shop drawing services.
All 3D work is done in AutoCAD and delivered as DWG. If your project requires a different 3D format, tell us at the start so we can confirm what is possible before quoting.
To build a reliable model from existing 2D drawings, we need enough information to define each element in all three dimensions. That usually means:
Where the 2D drawings leave something undefined, such as a sloping roof shown only on plan or a ceiling height that isn't stated, we list the assumptions we would make and confirm them with you before modelling. If the drawings are PDFs or scans, we first convert them to CAD and check the scale.
The finished model can be used to produce new sections, axonometric views, exploded views of assemblies and images for presentations.
The risk with any 3D model is that it and the 2D drawings drift apart: someone updates a sheet by hand, and the model no longer matches. On our jobs the model is the source. Sections, elevations and fabrication views are taken from it, and changes are made in the model first, then the affected sheets are regenerated and annotated. Each issue states which model revision the drawings were produced from, so you can always tell whether they agree.
Where only part of a project is modelled, such as a plant room or a feature staircase, the boundary between modelled and 2D-only areas is shown on a key plan, so nobody assumes the whole building has been coordinated in 3D.
We put the recommended format, what will be modelled or drawn, the revision allowance and the delivery date in writing before starting.
Need ongoing drafting support rather than a single set? See CAD drafting outsourcing.
In most cases, yes. Permit and NOC submissions are generally based on 2D plans, elevations, sections and details. A 3D model can support the design, but it doesn't replace the required drawings.
When the geometry is complex, when services are tightly packed into small spaces, when a fabricated item has to fit precisely, or when a client or developer needs to see the design to approve it.
Yes, if the drawings define the heights and levels as well as the plans. Where something is missing, we list our assumptions and confirm them with you before modelling.
3D models are built in AutoCAD and delivered as DWG files, with 2D sheets and images taken from them. If you need another format, ask before we quote so we can confirm what is possible.
Yes. We can extract axonometric views, sections and still images from the model to help explain a design.
Yes. We purge, audit and reorganise existing DWG files, rebuild exploded blocks, fix references and units, and move objects onto a proper layer structure.
Yes, for congested areas such as corridors, risers and plant rooms. The agreed solution is then drawn back into the coordinated 2D drawings.
Yes. Joinery, metalwork and other fabricated items can be modelled in 3D, with fabrication drawings taken directly from the model.
Modelling generally takes longer than 2D drafting of the same element, so it costs more. Modelling only the areas that benefit from it keeps the cost proportionate.
