Bridging design and reality: DXF and IFC Files in PIX4Dcloud
We spoke with Roger Johansenn from Universal Prosjekt Geosystemer AS, who specialize in high-precision data solutions for a wide range of applications, providing support at every stage of construction. Roger shared how PIX4Dcatch and PIX4Dcloud have become indispensable in his workflow.
PIX4Dcatch for documentation
First, Roger uses the 3D scanning application PIX4Dcatch to collect ground imagery and drones for aerial data collection. “What makes PIX4Dcatch particularly valuable to us is its powerful documentation capabilities,” says Roger. “This is crucial for our projects, where precision and visual overview play a key role.” By uploading to PIX4Dcloud or exporting to PIX4Dmatic, our company can deliver highly accurate and comprehensive documentation that meets even the most demanding project specifications
“This combination of simplicity and power makes PIX4Dcatch a natural part of our workflow and a tool we benefit greatly from in both daily and long-term projects. It’s an investment that truly delivers!" - Roger Johansen, CEO, Universalprosjekt Geosystemer AS
Through PIX4Dcloud, we share models and data via a simple URL, meaning recipients aren’t required to have specialized software. This saves time and eliminates technical challenges. Additionally, the seamless integration with our workflow allows us to quickly update and share new results as projects progress.
Combining 2D and 3D views for comprehensive project insights
One of the greatest advantages of PIX4Dcloud is the ability to showcase data in both 2D and 3D. This provides our partners with a visual and intuitive way to grasp the scope and details of the projects.
2D views are essential for analyzing surfaces, maps, and land planning. They combine CAD data, orthomosaics, and PDFs, which can be displayed together with adjustable opacity. This approach offers a comprehensive project overview by showcasing both the planned and as-built conditions within their real-world context. Using this material, we identified several errors caused by discrepancies in the projected designs.
3D models offer a realistic and detailed representation of terrain and structures. The 3D materials, except the point cloud, were sent to the excavator operator, who then has full control over the construction site directly from their machine controller. Simultaneously, we upload to PIX4Dcloud Advanced, allowing all involved parties to use it as a visual guide for project execution and communication. Together these two views they deliver a comprehensive insight.
Using the Design Overlay tool
Roger and his team use the Design Overlay tool in PIX4Dcloud to visualize and compare DXF and IFC files within their georeferenced 3D models and orthomosaics. This tool allows them to integrate design files into their projects for better understanding and decision-making.
Workflow with PIX4Dcloud’s Design Overlay tool
- Import files
We upload relevant design files, either DXF files (for technical drawings and floor plans) or IFC files (for BIM data, including structural details, material information, and 3D models)
- Position and alignment
Once the files are imported, they use the Design Overlay tool to accurately position the files over the existing model. DXF files are particularly useful for floor plans or topographical data, while IFC files provide more complex and detailed visualizations of buildings or structures
- Working with layers
DXF files: we activate specific layers within the DXF files to visualize only the elements relevant to the analysis, such as contour lines, utility networks, or building layouts
IFC files: we can show or hide various elements (e.g., walls, columns, or HVAC systems) depending on the project's focus
Comparison and validation
The Design Overlay tool enables Roger and team to compare the original design with the actual model generated from drone imagery or other data collection methods, offering a powerful and intuitive solution for integrating complex data from different formats into their projects. This helps Roger and the team:
- Provide an efficient way to ensure design aligns with reality
- Identify discrepancies between plan and real-world execution
- Simplify project management and documentation
- Enhance collaboration between designers, engineers, and project managers
- Communicate clearly with teams and stakeholders about necessary adjustments
For Universal Prosjekt Geosystemer, PIX4Dcatch and PIX4Dcloud have brought exceptional value to their projects. Integrating tools like the Design Overlay feature in PIX4Dcloud, has enabled them to seamlessly visualize and validate complex design files such as DXF and IFC directly within georeferenced 3D models.
The Design Overlay tool has proven to be a huge asset in Roger’s work. This combination of technology enables us to tackle complex challenges, maintain high standards, and deliver superior results. The integration of these tools into our workflow represents a significant advantage, empowering us to provide more value to our clients and partners.
“The collaborative approach of PIX4Dcloud ensures confidence among all parties involved and helps us deliver high-quality results efficiently. In short, PIX4Dcloud is a tool that not only simplifies our day-to-day operations but also elevates the standard for how we present and communicate our projects." - Roger Johansen, CEO, Universalprosjekt Geosystemer AS
