The fundamentals of 3D PDF
3D PDF represents a major evolution in technical documentation. This format allows the integration of interactive three-dimensional models into a standard PDF document, offering the possibility to visualize, manipulate, and analyze 3D objects without specialized software, since Adobe Reader is sufficient for operation.
Unlike traditional formats that often require expensive proprietary applications, 3D PDF democratizes access to CAD data. This accessibility significantly facilitates exchanges between different project stakeholders, whether they are engineers, decision-makers, or end customers.
In the manufacturing industry, 3D PDF is particularly valuable for:
- Technical documentation of complex products
- Instruction and maintenance manuals
- Interactive parts catalogs
- Advanced commercial presentations
- Communication between design offices and production workshops
The growing adoption of this format is explained by its ability to reduce interpretation errors, accelerate decision-making processes, and optimize collaboration within technical teams.
3DViewStation: The solution for converting your CAD models to 3D PDF
Multi-format import capabilities without compromise
In an industrial environment where CAD system heterogeneity is the norm, 3DViewStation stands out for its exceptional versatility. This solution allows importing the main native 2D and 3D CAD formats without requiring licenses for the original software, thus solving one of the major challenges of interoperability.
Among the supported formats:
- Native formats: CATIA, CREO/Pro-Engineer, NX, INVENTOR, SOLIDWORKS
- Neutral formats: STEP, JT, IGES, STL, VRML
- 2D formats: DXF/DWG, CALS, CGM, GERBER, HPGL
This extended compatibility ensures a smooth workflow, even in complex multi-CAD environments, eliminating bottlenecks often encountered during technical data conversion.
Visualization and management of PMI
3DViewStation excels in displaying and manipulating Product Manufacturing Information (PMI). The software not only allows viewing existing PMI in imported models but also creating and modifying 2D and 3D annotations.
This functionality transforms complex 2D designs into 3D PMI models, offering superior visual understanding of critical manufacturing information. Users can thus:
- Visualize tolerances and dimensional specifications
- Add precise technical annotations
- Integrate surface finishing information
- Save these annotations in different formats
Model compression and optimization
One of the major assets of 3DViewStation lies in its ability to significantly lighten CAD models. The software offers two complementary approaches:
- Import in BREP format (exact geometry): preserves the mathematical precision of the model
- Import in tessellated format (faceting similar to STL): significantly reduces file size
For maximum compression, the tessellated option offers several levels of detail, from the most precise to the lightest. Tests have demonstrated a compression rate of up to 90% compared to the native CAD model, without significantly altering visualization, physical property calculations, or measurement taking.
Intellectual property protection
3DViewStation integrates advanced features for protecting sensitive data, addressing a major concern of industrial companies. Users can:
- Remove internal parts of models to share only the outer envelope
- Apply alienation transformations to geometries to mask proprietary details
- Prevent model sectioning to avoid analysis of the internal structure
- Precisely control shared views, materials, and metadata
These mechanisms ensure that only necessary information is exposed when sharing technical documentation, thus preserving the company's competitive advantages.
Export to 3D PDF and other formats
After optimization, models can be exported in various formats, notably 3D PDF. 3DViewStation also supports:
- 3D formats: 3MF, ACIS, FBX, IGES, JT, Parasolid, STEP, STL, VRML
- 2D formats: PDF, BMP/JPG/PNG, DXF, SVG
This export flexibility allows adaptation to the specific requirements of each project and each recipient, ensuring optimal technical communication regardless of the IT environment.
SimLab: Enrich your 3D PDFs with animations and interactivity
Creation of scene states and dynamic animations
While 3DViewStation excels in importing and converting CAD models, SimLab specializes in transforming static 3D PDFs into highly interactive and dynamic documents.
SimLab Composer allows configuring different scene states and integrating animations to make your models dynamic and engaging. Users can create:
- Simple animations (rotation, translation of a component)
- Assembly/disassembly sequences
- Mechanical operation demonstrations
- Transformations between different product configurations
This temporal dimension considerably enriches the informative value of technical documents, allowing intuitive understanding of complex processes without requiring detailed textual explanations.
Advanced customization options
SimLab offers an impressive level of customization for your 3D PDFs:
- Configuration of controllable options allowing customers to build their own configurations
- Customization of user interface and buttons
- Style adaptation to design requirements and brand image
- Application of realistic textures through "texture baking"
- Creation of photorealistic renderings integrated into the document
These features allow creating highly professional documents perfectly adapted to your visual identity, reinforcing the impact of your technical communication.
Intuitive interaction and navigation
Ergonomics constitutes a fundamental aspect of 3D PDFs created with SimLab. Users benefit from:
- Smooth navigation in 3D models via standard software like Adobe Reader
- Integrated measurement and annotation tools
- Interactive actions making objects clickable
- Connections between objects, scene states, and animation sequences
- Customization of interactive behaviors without programming
These interaction features transform a passive document into an immersive experience, facilitating the understanding of complex technical information and significantly improving user engagement.
Simplified creation process
SimLab distinguishes itself by the simplicity of its creation process, structured in minimal but effective steps:
- Choice of PDF template and parameter configuration
- Configuration of scene states and animations
- User interface customization
- Export of the finalized 3D PDF
This streamlined approach allows even non-specialist users to quickly create professional-quality interactive 3D documents, thus democratizing access to advanced technical communication tools.
Practical guide: from CAD import to creating an interactive 3D PDF
