AI Copilot

Generate model elements, analyze architecture, and get intelligent assistance for your design decisions

​
Requirements & Traceability

Capture, organize, and trace requirements from specification to implementation with full bidirectional traceability.

Requirements Management

Capture requirements, build hierarchies, assign to systems, and track verification status

Import & Export Requirements

Import requirements from Excel and CSV, export for reporting and compliance documentation

​
Analysis & Safety

Make informed engineering decisions with structured analysis tools and comprehensive safety workflows.

Trade Studies

Compare design alternatives against weighted criteria to make objective engineering decisions

Hazards & Safety

Identify hazards, assess risk levels, and track mitigation controls for system safety analysis

Test Cases

Plan, execute, and track verification tests with full traceability to requirements

​
Collaboration & Documentation

Work together in real-time, manage documents, and maintain version history across your team.

Real-time Collaboration

Invite team members, assign roles, and work together on models simultaneously

Documents Hub

Upload specs, drawings, 3D models, and link them to the parts they describe

Version Control

Create snapshots of your model and restore to any previous state when needed

Integrations

Connect with Excel and other tools to fit into your existing engineering workflow

​
Why Engineering Teams Choose Dalus

Move beyond documents and spreadsheets to a single source of truth. Dalus captures your system architecture, requirements, and analysis in one connected model that stays in sync as your design evolves.
The AI Copilot understands your model context and can generate parts, analyze architectures, process requirements from documents, and answer questions about your system design.
Every requirement traces to system elements, every test case links to what it verifies, and every design decision is documented. Navigate relationships bidirectionally to understand impact and coverage.
Work with your team simultaneously on the same model. See changes in real-time, manage permissions with roles, and maintain a complete audit trail of who changed what and when.
