3D CAD Workflow

How Our 3D CAD Drafting Services Workflow Works

Our 3D CAD Drafting Services follow a structured workflow from drawing review and project setup through 3D model development, technical checks and final delivery. The process is configured around the available design information and agreed CAD outputs.

Project Inputs

What Should You Send for 3D CAD Modeling?

The modelling process starts with the latest available drawings, sketches, technical information and clearly defined project requirements.

2D CAD Drawings Available plans, elevations, sections and technical CAD information.
Design Sketches Concept sketches and project markups that define required geometry.
Blueprints Available project drawings used as reference for model development.
Engineering Details Relevant dimensions, component information and technical details.
Required Disciplines Architecture, structure, MEP, mechanical or defined combinations.
Expected Deliverables Required model content, views, drawings and project-specific outputs.
CAD specialist reviewing detailed three dimensional CAD geometry and technical project drawings
A defined 3D CAD workflow helps maintain consistent geometry, dimensions and model structure as project information develops from drawings into three-dimensional CAD.
5-Step CAD Process

From Project Drawings to Structured 3D CAD Geometry

Each stage focuses on developing the required three-dimensional model while maintaining the agreed drawing information, dimensions and project scope.

01
Review

Assess Project Inputs

Review available drawings, sketches, dimensions, engineering details and required 3D CAD deliverables.

02
Define

Confirm CAD Scope

Define model boundaries, required disciplines, geometry, reference information and final project outputs.

03
Model

Develop 3D Geometry

Build the required architectural, structural, MEP or mechanical geometry from the supplied design information.

04
Check

Review CAD Model

Check model geometry, dimensions, alignment and agreed project requirements before final issue.

05
Deliver

Issue CAD Outputs

Prepare the agreed 3D CAD model, drawing views and supporting technical outputs for project delivery.

Model Definition

Define the CAD Requirements Before Modeling Begins

A well-defined scope helps the CAD team understand what needs to be modelled, how detailed the geometry should be and which outputs the project team requires.

Model Scope Define which building, system, equipment or components require modelling.
Required Detail Confirm the geometric detail needed for the intended project use.
Dimensions Provide available dimensions and technical reference information.
CAD Standards Share applicable project naming, layering or documentation requirements.
Software Workflow Confirm the required CAD environment and downstream project use.
Final Outputs Define required models, drawing views and technical deliverables.
CAD Quality Review

What Do We Review Before Delivery?

Quality checks focus on the agreed model scope and the technical information available for the project.

Geometry Model form reviewed against the supplied project information.
Dimensions Key dimensions checked against available drawing references.
Alignment Defined components reviewed for positioning and relationships.
Model Structure CAD organisation reviewed against the agreed project workflow.
Required Views Requested project views checked before final delivery.
Scope Compliance Final outputs reviewed against the agreed CAD requirements.
Source Information Matters

Model development depends on the drawings, dimensions, sketches and technical information available for the project.

Define Detail Early

Agree the required model detail and deliverables before drafting begins to keep the CAD scope focused.

Clarify Missing Information

Where source information does not clearly define geometry or dimensions, clarification should come before unsupported assumptions.
