What's included
45+ rules. Ready to run.
The free version gives you a complete picture of the most common data quality problems in Revit models — organised across four categories.
13
Best practice rules
Common modelling habits that create problems downstream — caught before they compound.
10
Performance rules
Elements and settings that slow down your model or cause instability in large projects.
12
Data consistency rules
Parameter values that contradict each other or don't match what downstream systems expect.
10
Standards rules
Cross-country checks against general BIM standards applicable to most projects.
Engineers working in the Netherlands get access to additional BIM Basis ILS checks at no cost. More country-specific rule sets are in development.
How it works
Live feedback. Inside Revit.
DAQS Assist runs in the background as you model. When something fails a rule, you see it immediately — with context on why it matters and how to fix it.
Detailed issue list
Every failed check is listed with a description, severity level, and guidance on how to resolve it.
Filterable by type
Filter issues by category — critical, performance, best practice — so you focus on what matters most right now.
No export required
Analysis runs on your work-in-progress model directly in Revit. No IFC export, no external tools.
Rule explanations included
Each rule comes with an explanation of why it exists — not just what failed.
Free forever
The free version has no time limit. Use it for as long as it's useful — upgrade only when you need more.
Single shared project
Free accounts share a single project environment. Teams needing project-level separation can upgrade to premium.
