Why a CAD Brief Matters

One of the most common reasons engineering projects experience delays is unclear project information.

When a CAD team starts work without understanding project goals, requirements and deliverables, the result is often:

• Multiple revisions

• Communication issues

• Missed expectations

• Project delays

• Increased engineering costs

A well-prepared CAD outsourcing brief helps align expectations from the beginning and creates a clear foundation for successful project execution.

Define the Project Objective

Start by clearly explaining what the project is trying to achieve.

Examples include:

• New product development

• Existing product modification

• Reverse engineering

• Manufacturing drawing creation

• Sheet metal design

• Prototype preparation

• Assembly modelling

The CAD team should understand the final objective before development begins.

A clear objective helps guide engineering decisions throughout the project.

Provide Available Reference Material

The more information available at the start of a project, the more efficiently engineering work can proceed.

Useful references may include:

• Hand sketches

• Existing drawings

• Product photographs

• PDF documents

• Technical specifications

• Sample parts

• Prototype images

• Customer requirements

Providing reference material early helps reduce assumptions and improves design accuracy.

Define Required Deliverables

A CAD project should always include a clear list of expected outputs.

Common deliverables include:

• 3D CAD models

• Manufacturing drawings

• Assembly drawings

• BOMs

• STEP files

• IGES files

• DXF files

• DWG files

• PDF drawing packages

Defining deliverables early helps prevent misunderstandings later in the project.

Specify CAD Software Requirements

If your organization uses a specific CAD platform, communicate this at the start of the project.

Examples include:

• SolidWorks

• AutoCAD

• Fusion 360

• Creo

• Inventor

• CATIA

Software requirements can affect workflow, file compatibility and project execution.

Clarifying this information early helps avoid conversion issues later.

Explain Manufacturing Requirements

The CAD team should understand how the product will be manufactured.

Common manufacturing methods include:

• CNC machining

• Sheet metal fabrication

• Injection moulding

• Welding

• Casting

• 3D printing

Manufacturing requirements influence design decisions, tolerances and documentation.

Providing this information helps improve manufacturability and reduce future revisions.

Define Timeline Expectations

Every project should include realistic schedule expectations.

Important information includes:

• Project start date

• Review milestones

• Approval stages

• Final delivery date

Establishing a timeline helps both parties plan resources and manage project priorities.

Clarify Revision Process

Engineering projects often require revisions.

Before work begins, define:

• Number of review rounds

• Approval process

• Revision submission method

• Communication channels

A clear revision process helps maintain project momentum and reduces confusion.

Identify Key Contacts

Projects move more efficiently when communication channels are clearly defined.

The brief should identify:

• Primary project contact

• Technical reviewer

• Decision maker

• Procurement contact if required

Having designated contacts helps streamline communication and approvals.

Common Information Missing From CAD Briefs

Many outsourcing projects start with incomplete information.

Commonly missing items include:

• Manufacturing process

• Required file formats

• Material specifications

• Timeline expectations

• Deliverable requirements

• Revision procedures

Addressing these items early helps improve project outcomes.

Conclusion

A well-prepared CAD outsourcing brief improves communication, reduces revisions and helps engineering projects progress more efficiently.

By clearly defining objectives, deliverables, manufacturing requirements, software preferences and timelines, companies can create a smoother outsourcing experience and achieve better engineering results.

Investing time in project preparation often saves significantly more time during execution.
