Design Reviews Made Easy: Using 3D Markup, Annotations & Feedback Loops in 3DEXPERIENCE Platform

We explored how Engineering Items, Revisions, and Change Actions create structured control within the product development process. However, structured change management is only effective when design reviews are equally controlled, collaborative, and traceable.

This is where 3DEXPERIENCE Platform extends its value beyond modelling — by transforming design reviews from static meetings into interactive, data-driven feedback loops directly connected to product data.

Why Traditional Design Reviews Slow Engineering Down

In many organisations, design reviews still rely on exported PDFs, screenshots, slide decks, or neutral file formats shared over email. Feedback is often disconnected from the actual 3D model, leading to unclear comments, misinterpretation of geometry, and fragmented communication between departments.

Common challenges include:

• Comments stored outside the CAD system
• No traceability between feedback and revision updates
• Difficulty involving non-CAD stakeholders
• Manual consolidation of review inputs
• Rework caused by misunderstood markups

Another common bottleneck occurs when stakeholders need to open the 3D model using a full design license just to perform reviews. In environments where CAD licenses are limited, this often interrupts designers’ work because review activities temporarily occupy the licenses needed for actual design tasks.

When review data lives separately from the product definition, engineering teams lose both efficiency and accountability.

3D Markup: Reviewing Models Directly in the Browser

With the 3D Markup capabilities available in the 3DEXPERIENCE Platform web client, stakeholders can review models directly in a browser-based 3D environment — without requiring a full CAD installation or consuming a design license.

Using 3D markup tools, reviewers can:

• Add comments directly onto geometry
• Highlight specific faces, edges, or components
• Attach contextual notes to assemblies
• Capture snapshots of the current model state

Because markups are associated with the Engineering Item and its specific revision, feedback remains linked to the exact version under review. This eliminates ambiguity about which model version a comment refers to and ensures discussions stay anchored to live product data rather than static files.

Just as importantly, reviewers no longer need to interrupt designers to access the model. As long as they have an internet connection and a valid login to the 3DEXPERIENCE Platform, they can open the 3D data instantly and participate in the review process.

Accessible Anywhere, No Installation Required

Since 3D Markup runs directly in the web client, it does not require any software installation. This dramatically simplifies collaboration across teams and locations.

Stakeholders can access and review 3D data from:

• Desktop computers
• Laptops
• Tablets
• Smartphones (iOS or Android)

Imagine a project manager reviewing a mechanical assembly on a tablet during a meeting, or a manufacturing engineer highlighting a clearance issue directly from a smartphone while walking through the production floor.

This level of accessibility makes design reviews faster, more flexible, and far easier to involve cross-functional teams who may not normally work inside CAD environments.

Annotations: Embedding Engineering Intent into the Model

Beyond visual comments, annotations allow engineering intent to be embedded directly within the 3D definition. Instead of relying solely on 2D drawings for communication, teams can apply:

• Dimensional annotations
• Tolerances
• Manufacturability notes
• Assembly instructions

These annotations remain connected to the product structure, supporting model-based definition (MBD) strategies and reducing dependency on external documentation.

This is particularly valuable in regulated industries where traceability of design intent is critical. By embedding design intent directly within the model, engineering teams improve alignment across simulation, tooling, and manufacturing processes.

Structured Feedback Loops with Change Integration

The real power of design reviews on the 3DEXPERIENCE Platform lies in structured feedback loops. Review comments and markups can be formally linked to Change Actions when modifications are required.

Instead of informal discussions that may be forgotten or misapplied, feedback transitions into controlled engineering change workflows.

For example, if a manufacturing engineer identifies a clearance issue during review, the comment can trigger a Change Action. The impacted Engineering Item is revised, updates are validated, and the lifecycle state transitions only after approval. Every step remains digitally traceable.

This closes the loop between review and implementation, ensuring that feedback does not remain theoretical but becomes part of a controlled product evolution process.

Real-World Scenario: Cross-Functional Design Validation

Consider a mechanical assembly undergoing final design validation before release.

Design engineers complete the modelling, and the product enters the review phase. Instead of exporting files, stakeholders from manufacturing, procurement, and quality access the model directly through the 3DEXPERIENCE Platform web client.

A manufacturing engineer uses 3D markup to highlight an interference risk near a mounting bracket. A service engineer annotates access clearance concerns for maintenance. The project manager adds timeline-related comments regarding release readiness.

All feedback is captured in a structured environment linked to the specific revision under review.

The design team evaluates the inputs, initiates Change Actions where necessary, creates updated revisions, and resubmits the assembly for approval. Once validated, the lifecycle state transitions to Released, allowing manufacturing to proceed using verified and fully reviewed data — supported by a complete digital audit trail of decisions and modifications.

From Review Meetings to Continuous Collaboration

By combining 3D Markup, annotations, and structured feedback workflows, the 3DEXPERIENCE Platform transforms design reviews from periodic meetings into continuous collaboration cycles.

Review discussions are no longer detached from the model — they are embedded within it.

This approach delivers:

• Faster review cycles
• Reduced miscommunication
• Improved cross-functional collaboration
• Full traceability of feedback and decisions
• Lower risk of late-stage engineering changes

In modern product development, design reviews are not simply checkpoints — they are strategic control points. When connected directly to Engineering Items, Revisions, and Change Actions, they become a critical driver of quality and innovation.
