Technical data exchange between different CAD systems represents a major challenge for engineering and design companies. Spirit software, developed by Softtech, offers significant but often overlooked interoperability capabilities. This article presents a comprehensive analysis of Spirit's data exchange functionalities and proposes solutions to optimize the interoperability of your models in a multi-CAD environment.
Presentation of Spirit Software and its Position in the CAD Ecosystem
Spirit is a 2.5D computer-aided design (CAD) software developed by Softtech. 2.5D (also called two-and-a-half-D or pseudo 3D) refers to design technologies that are halfway between 2D and 3D. This software is particularly suited for architectural and civil engineering projects, offering a BIM (Building Information Modeling) solution that allows architects, engineers, and designers to create models with limited depth dimension.
Unlike complete 3D CAD systems, Spirit distinguishes itself with its 2.5D approach that offers users the ability to work using several methods:
- Traditional 2D drawing with extrusion elements
- 2.5D modeling with depth management
- Component-oriented design (particularly useful for the BIM approach)
What makes Spirit particularly interesting in a CAD interoperability context is its ability to integrate into heterogeneous workflows, while recognizing its technical limitations compared to complete 3D systems.
History and Evolution of Spirit Data Exchange Capabilities
The development of Spirit is part of a constant improvement approach based on user feedback and the expertise of Softtech employees, many of whom have practical experience as architects, planners, or engineers. This "from practice" approach has influenced the evolution of the software's interoperability capabilities.
Over the years, Spirit has significantly improved its exchange interfaces to meet the growing demands for collaboration in the industry. The optimization of the IFC (Industry Foundation Classes) interface demonstrates this commitment to implementing a true "open BIM," although developers recognize that the path to perfect interoperability is still long.
Notable improvements include:
- Continuous refinement of the IFC interface
- Optimization of IFC model representation
- Significant improvement in graphic exports
- Development of direct exports to specific formats such as SketchUp 3D
This constant evolution positions Spirit as a committed player in resolving CAD interoperability issues that occur "recurrently and at all stages of a product's lifecycle."
Technical Architecture and Geometric Engine of Spirit
Spirit relies on a technical architecture adapted to its 2.5D nature, which directly influences its CAD data exchange capabilities.
Modeling capabilities and data representation:
Spirit manages several geometric data representations, including:
- Extended 2D models with depth information (2.5D)
- Mesh models for export to formats like STL
- Limited parametric data adapted to architectural design
This 2.5D approach directly influences interoperability possibilities, as the software does not manipulate complete volumetric models like 3D CAD systems do. Spirit also seems to support specialized architectural modeling, as indicated by the ZAC extension (Spirit Architectural Component).
The software's flexibility in terms of interoperability remains one of its strengths in its market segment, allowing users to exchange data with other applications, taking into account the inherent limitations of 2.5D modeling.
Native and Exchange Formats Supported by Spirit
Format support is a key element of CAD interoperability. Spirit distinguishes itself through its compatibility with several file formats, both for import and export, although more limited than complete 3D CAD systems.
Spirit native formats:
| Extension | Description | Usage |
|---|---|---|
| .SPIRIT | Main format for Spirit drawings | Native model saving |
| .ZAC | Spirit Architectural Component | Specific architectural components |
| .BT! | BitSpirit Incomplete Download File | Temporary files |
| .TEW | Wrestling Spirit | Specialized format |
Standard formats for import/export:
| Format | Import | Export | Main Use |
|---|---|---|---|
| DWG/DXF | ✓ | ✓ | Collaboration with AutoCAD users |
| STL | ✓ | ✓ | 3D printing, rapid prototyping |
| SketchUp | ✗ | ✓ | Sharing with construction professionals |
| IFC | ✓ | ✓ | BIM exchange (Building Information Modeling) |
It is important to note that Spirit, as a 2.5D software, cannot import or export advanced 3D formats like STEP or ACIS. This limitation is inherent to its technical architecture and determines the possible interoperability scenarios.

- STL export for physical modeling needs
These approaches take into account the limitations of Spirit as 2.5D software and optimize exchange with other systems.
Validation before Spirit data exchange:
Before any Spirit data exchange, it is essential to:
- Check the quality of the model to detect possible geometric errors
- Test the export in the target format to confirm the preservation of critical data
- Compare the exported model with the original model to identify differences
These validation steps ensure that your partners will receive usable data that meets your expectations.
Adaptation to specific Spirit data exchange needs:
The export must be adapted to the intended use of the model:
- For technical documentation: prioritize DWG/DXF formats
- For BIM collaboration: IFC format with preliminary verification
- For 3D printing: STL export with optimized parameters
- For feasibility studies: STL export for physical model printing
A preliminary analysis of the recipient's needs allows choosing the most appropriate exchange format, while taking into account the limitations of 2.5D.
