## Executive Snapshot
**What it is:** CAD Assistant is an offline 3D CAD and mesh model viewer for iOS, utilizing Open CASCADE Technology.
**Why users hire it:** Engineers hire this tool to inspect complex CAD geometry on mobile devices without needing a desktop workstation, so the lack of updates threatens the long-term utility of the viewer.
<!-- /section:executive-snapshot -->

<!-- section:features -->
## App DNA (Features & Intent)
- **[Standard] Multi-format CAD/Mesh Viewer:** Renders 3D models from BREP, IGES, STEP, STL, PLY, OBJ, JT, and glTF formats using OCCT components.
- **[Differentiator] Interactive Scalar Data Visualization:** Displays mesh elements colored by scalar quantities with adjustable interactive color scales.
- **[Differentiator] Format Conversion:** Exports loaded CAD or mesh models into alternative formats including STEP, IGES, BREP, PLY, STL, OBJ, and glTF.
<!-- /section:features -->

<!-- section:market-position -->
## Market Position {#market-position}

CAD Assistant maintains a niche position as a free, offline-first CAD viewer with a 4.05 rating, but its lack of updates since 2018 leaves it trailing behind active competitors.
<!-- /section:market-position -->

<!-- /section:sentiment -->
<!-- section:swot -->
## SWOT Analysis {#swot}

**Core Strengths:**
- OCCT rendering engine provides reliable geometry handling
- Multi-format support covers standard industrial file types

**Critical Frictions:**
- No updates since 2018 creates compatibility risk
- 20 total ratings indicate low user engagement
- No cloud-sync functionality

**Growth Levers:**
- Integrate cloud-storage APIs for file management
- Add AR-viewing mode for field inspection

**Market Threats:**
- Nomad Sculpt's rapid update cycle captures attention
- Modern mobile CAD tools render static viewers obsolete

<!-- /section:swot -->
## Recent Changes (v2 → v3) {#recent-changes}

The report identifies a transition from a stable legacy utility to a declining product as the competitive landscape shifts toward active, feature-rich alternatives.

**Overall trend**: Declining
**Compared at**: 2026-05-26

### High-impact changes
- **[Declined] Outlook Trend** (positioning) — Outlook trend: stable → declining.
- **[Shifted] Competitive Landscape** (positioning) — Removed direct CAD nemeses (Shapr 3D) and replaced with a broader, less focused set of productivity and conversion tools.

### Medium-impact changes
- **[Added] New Threats and Opportunities** (swot) — Added specific threats (Nomad Sculpt) and opportunities (AR-viewing) to the SWOT analysis.
- **[Added] Updated Feature Gaps** (features) — Feature gaps updated to include remote print management and biometric archive locking.

<!-- section:whats-new -->
## What's New

- **Latest (v1.2, 7 years ago):** Added glTF 2.0 export support and the ability to rename assembly parts.
<!-- /section:whats-new -->

<!-- section:momentum -->
## App Momentum (Zombie) {#momentum}

- No feature updates since 2018.
- Maintains stable legacy user base.

> **Cadence:** 1 total versions · 1 majors in last 6 months · 2754 days since last update

<!-- /section:momentum -->

<!-- section:so-what -->
## The "So What?" (Strategic Takeaway) {#so-what}

CAD Assistant is an established productivity app that is completely free.
With a 4.05/5 rating from 20 reviews, it shows polarized user reception.

<!-- speakable-start -->
> **Bottom Line:** CAD Assistant provides a reliable rendering engine for industrial CAD formats, but the lack of updates since 2018 makes it a liability for professional workflows, so the team should prioritize a stability audit or sunset the app.
<!-- speakable-end -->

**Best for:** Engineers and 3D designers who need to view or convert CAD and mesh files on mobile devices.

<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [MAINTAIN] [HIGH IMPACT] Audit compatibility for current iOS because the app has not been updated since 2018 → maintain baseline utility — *The 2018 last-updated date creates a high risk of crashes on current iOS versions.* _(trade-off: deprioritize Pause all new feature development — stability is the priority for professional users.)_
<!-- /section:pm-actions -->

<!-- section:feature-gaps -->
### Feature Gaps vs Competitors

- Real-time remote print management (available in RC Klipper 3D)
- Biometric archive locking (available in ChatExport)
- Advanced multiresolution sculpting (available in Nomad Sculpt)
<!-- /section:feature-gaps -->

<!-- section:outlook -->
### Outlook: Declining

The mobile CAD market is shifting toward cloud-connected, feature-rich design tools, leaving static viewers like CAD Assistant increasingly isolated. Without a commitment to modern OS support, the app will continue to lose relevance to active competitors, so the team must decide whether to refresh the codebase or sunset the product.

- 🔴 The lack of updates since 2018 indicates the app is in maintenance mode, which erodes trust for professional users requiring modern OS support.
- 🔴 Competitors like Nomad Sculpt maintain a high release cadence, which shifts user expectations toward active, feature-rich mobile design tools.
