The world of design and surveying requires increasingly faster, integrated, and accessible tools. With this goal in mind, Trispace NX was born, the new 2D web CAD of the GeoStru NX suite. Specifically designed for the needs of engineers, architects, agronomists, surveyors, and geologists, this software redefines the concept of technical drawing by combining the power of a desktop CAD with cloud accessibility and the innovation of Artificial Intelligence.
Trispace NX Web CAD: The Desktop Experience, Without Any Installation
Unlike traditional software, Trispace NX works entirely from the browser: it requires no installation and does not bind the user to hardware-specific licenses.
Despite its web-based nature, the application offers the same fluid and complete experience as a classic desktop CAD. It features all the fundamental drawing tools (lines, polygons, arcs, texts), editing tools (trim, offset, linear and polar array), and a complete system for the standard management of layers, blocks, and dimensions. Files can be imported and exported in the industry-standard formats, namely DXF and DWG.
A strong point is the advanced snap engine, which includes options like end, mid, center, quadrant, perpendicular, and intersection, with a practical yellow marker confirming the exact snap point before every click.
Processing Point Clouds and DTM Models with Trispace NX Web CAD
Where Trispace NX clearly stands out from generic CADs is in the management of advanced topographic data. The software integrates a guided wizard capable of importing point clouds from surveys carried out with drones (DJI, Trinity, Phantom, Yellowscan), laser scanners, or Matterport systems in las, laz, and xyz formats.
Processing happens with surprising speed and entirely client-side: the WASM laz-perf decoder reads and decimates up to 50 million points, reducing them to manageable quantities (e.g., 15,000 points) in just ten seconds, without any upload to external servers. It is also possible to filter data using ASPRS classification, quickly isolating bare earth (class 2) or high vegetation (class 5).
With a single click, the Trispace NX algorithm performs a Delaunay triangulation server-side, transforming the point cloud into an ultra-high-precision digital model (mesh) in just a few seconds. From this surface, the professional using the web CAD can quickly extract crucial information:
- Contour lines: Generated automatically (e.g., with a step at 10% of the elevation difference) or set manually.
- Slope map: Each triangle is colored based on its angle (green under 15 degrees, yellow up to 30, orange at 45, red beyond), providing an essential representation for hydrogeological risk assessment plans.
- Topographic cross-sections: By drawing a line on the mesh, the elevation profile of the terrain is instantly obtained, exportable in DXF, GeoJSON, or as an image.
- Volume calculation: By entering a project plane elevation, the system integrates triangle by triangle to calculate cut (in red) and fill (in blue) volumes, ideal for earthwork calculations.
Map Calibration and Helmert Alignment in the Web CAD
Working with orthophotos, scanned official maps, or georeferenced screenshots is a daily practice. Trispace NX allows dragging these raster images onto the canvas and, through a calibration wizard, anchoring them to real metric coordinates by providing just two known latitude and longitude points. From that moment, every click queries a global DEM (Digital Elevation Model), returning exact coordinates (X-Y world, East-North metric) and the elevation of the point.
Furthermore, Trispace NX offers an elegant solution to a frequent problem: the overlapping of point clouds in local coordinates and georeferenced orthophotos. With the Helmert tool integrated into this 2D CAD, it is sufficient to select two to three pairs of homologous points (e.g., the corner of a building visible on both surveys); the algorithm, using the least squares method, calculates scale, rotation, and translation all at once, hooking the 3D survey to real coordinates with extreme precision.
The Artificial Intelligence of Trispace NX Web CAD at the Professional’s Service
Trispace NX doesn’t just aim to be a great CAD: it takes a leap into the future by integrating an Artificial Intelligence designed for specific tasks.
The Vision module of this innovative web CAD can analyze a photograph of a freehand sketch (e.g., a building plan taken on-site) and transform it into a real CAD drawing in just ten seconds. It recognizes walls, doors, and dimensions, outputting metric-scaled polylines onto a dedicated layer.
Additionally, the system supports interaction via natural language commands. Instead of memorizing complex macros, you can simply write actions like “triangulate”, “decimate ten thousand”, or ask in words to extract a cross-section; the backend with tool-calling will interpret the request and directly modify the project database without intermediate steps.
Integration of Trispace NX into the GeoStru Ecosystem
Trispace NX stands as the ideal front-end for the entire GeoStru ecosystem. The triangulated mesh, for example, can be colored by geomechanical materials (granite, limestone, etc.) and exported as CSV files to feed specialized software like GEOROCK 3D for rockfall analysis.
All the work done – which includes layers, blocks, meshes, calibrated rasters, and cross-sections – is constantly saved in the background in the browser (thanks to localStorage) and enclosed in a single project file with the .cadproj extension. This drastically simplifies sharing information with colleagues, eliminating the need to manually export different files for every single deliverable.
To test the potential of this revolutionary tool and immediately optimize your technical and topographic design workflow, Trispace NX is already available at geostru.ai.
