PractiCal AR vs OnsiteBIM

PractiCal AR helps FIRST® Robotics Competition teams calibrate and check practice field AprilTag placement using augmented reality and AprilTag detection. Use your device to detect AprilTags, build a field map, compare detected tag positions against an ideal field layout, and export the results for use in other tools. APRILTAG DETECTION Detect AprilTags in real time using your device’s camera and ARKit. Each detected tag is shown in the AR view with its 3D pose so you can see position and orientation while scanning . FIELD CALIBRATION Scan your practice field AprilTags and compare their detected positions against the official field layout. CALIBRATION REPORT View a table showing Ideal vs. Actual tag placement, then export the report as CSV, JSON, or Markdown. 3D FIELD MODEL View this season’s simplified field CAD model in a 3D viewer, or place it in your environment using AR. REVIEW MODE Review saved calibration data in the app without needing to be in front of the field. EXPORT YOUR DATA Export your field calibration data in WPILib JSON format and Limelight JSON format. AR GAME Use your a practice or competition field to play four AR mini-games — launch fuel balls at the hub targets on the field and track your scores. Play the games from the stands, no need to do any calibration of the field, other than using PractiCal to detect and pin a single tag, all from the stands. The included games are: - Quick Shot — Score as many as you can in 20 seconds - Hot Shot — Build the longest streak without missing - Long Shot — Go for distance — how far can you score from? - Top Shot — How good is your accuracy rate? The game features: - Real-time ball physics with adjustable launch speed and angle - Aim with your camera. NOTE: The game and scores are specific to REBUILT and will be removed at the beginning of the 2027 FRC season. Leaderboard participation is optional and only displays user provided 3 letters and FRC team #. Useful settings for calibrating tags from a distance is in Settings -> Calibration * Tap to recenter all tags * Snap tags to vertical The higher the resolutions and lower the decimation, the farther you can be. You can also detect closer and walk away, ARKit will know how fr you've gone. PractiCal AR is free, with no in-app purchases or ads. Built by an FRC mentor for the FRC community. Requires a device with ARKit support and a camera. Works best in a well-lit environment with clearly visible AprilTags.

See your BIM model where it belongs: on the jobsite. OnsiteBIM brings BIM and construction together by placing 3D building models directly into the real world using your iPhone or iPad. Inspect, navigate, measure, and compare digital building models against physical construction—from active floor plates and mechanical rooms to basements and remote jobsites. HOW IT WORKS — FROM OFFICE TO JOBSITE Open Your 3D Model Open BIM and CAD models directly from your device, Apple Files, iCloud Drive, Google Drive, OneDrive, Dropbox, Egnyte, or other supported storage. Place Your Alignment Target Tape a printed Alignment Target to a known column, wall, or floor benchmark. Free print-ready targets and Revit families can be generated by your office or VDC team using the tools at www.onsitebim.app. Aim Your Camera & Inspect at 1:1 Scale Point your camera at the target, and your 3D model locks into place at 1:1 scale for real-world inspection. Alignment Targets are physical positioning anchors for your models—not QR codes or download links. POSITION YOUR MODEL YOUR WAY Use Alignment Targets for automatic positioning or place models manually when targets aren't available. • Auto Target Alignment — Position models in real-world space using a printed Alignment Target, including position, elevation, and orientation. • Manual Surface Placement — Place models on floor surfaces using joystick navigation, rotation controls, and elevation nudging. SEE EXACTLY WHAT MATTERS Filter individual BIM and CAD layers or use MEP ONLY to instantly hide architectural elements and isolate the systems you need. • HVAC ductwork • Plumbing pipes • Fire suppression • Electrical conduits and cable trays • Structural elements and rebar sleeves WORK WITH MAJOR BIM & 3D FORMATS Open models without requiring cloud conversion: • IFC — OpenBIM models, including IFC 2x3 and IFC4 • GLB & glTF — 3D models with PBR materials • USDZ — Apple spatial 3D models • OBJ & STL — 3D geometry with selectable measurement units Compatible with models exported from Autodesk Revit, Navisworks, SolidWorks, Archicad, Rhino, and SketchUp. MIX DIGITAL MODELS WITH THE REAL WORLD Use supported LiDAR-equipped devices to improve spatial understanding between your digital model and physical surroundings. • Real-Time LiDAR Occlusion — Physical walls, slabs, columns, and other surfaces can hide virtual geometry positioned behind them. • Interactive Transparency — Inspect digital building systems behind physical surfaces or inside concrete forms. CONTROL MODEL VISIBILITY Adjust model opacity from 0% to 100% to cross-reference virtual MEP runs, conduit racks, equipment, and other building elements against physical jobsite conditions. MEASURE IN 3D Use the surface-aligned 3D tape measure to verify clearances, slab elevations, and spatial relationships between physical surfaces and virtual model elements. Measurements are displayed in metric and imperial units. WORK WITHOUT THE CLOUD OnsiteBIM is designed for jobsites where network connectivity isn't always available. • On-Device Processing — 3D model parsing, spatial tracking, and rendering run directly on your device. • Work Offline — Inspect models in basements, mechanical rooms, tunnels, and remote jobsites without Wi-Fi or cellular connectivity. • Private by Design — Your 3D model geometry remains on your device during model processing and inspection. BUILT FOR THE JOBSITE A field-focused interface designed for active construction environments: • High-contrast HUD for bright outdoor environments • Large, glove-friendly touch targets • 2D directional joystick navigation • Precision elevation nudging • Thermal and battery optimization for extended inspection sessions COMPANION WEB TOOLS Free tools for offices and VDC teams, including Revit families, IFC export profiles, and Alignment Target generation, are available at www.onsitebim.app. Bring your BIM model to the jobsite.
