HoloLens 2 CAD Viewer for HPUs and Hydraulic Valves

Problem Statement: Engineers needed to inspect large CAD assemblies (HPUs and hydraulic valves) at true scale with hands‑free interaction for reviews, training, and stakeholder demos.

Solution: I built a HoloLens 2 application using MRTK and OpenXR that loads prepared CAD models, supports inspection and part isolation, and provides intuitive gesture‑based controls. The app leveraged spatial mapping and anchored placements for stable viewing in real environments.

Skills Used:

  • C#
  • Unity
  • MRTK
  • HoloLens 2
  • OpenXR
  • XR
  • MR
  • AR

Development Process

Requirements & Model Prep

Converted and decimated CAD assets, defined inspection use cases (explode, isolate, highlight), and set performance targets.

Interaction Design

Implemented MRTK-based gestures and tool panels; ensured discoverable controls with minimal onboarding.

Anchoring & Spatial UX

Used spatial mapping/anchors to place assemblies reliably and maintain alignment during sessions.

Field Validation

Tested in office and lab settings for stability, clarity, and comfort over extended viewing.
