Revit Tip: Best Practices for Revit Project Parameters — Setup, Use, and Governance

Project Parameters are the fastest way to capture non‑standard information in your Revit model and make it schedulable, filterable, and reviewable across teams.

Good candidates for Project Parameters:

• QA/Issue tracking (Yes/No flags like Needs Review, Field Verified)
• Specification Section, System Zone, Responsibility (Trade)
• Asset ID, Warranty Period, Maintenance Class
• Commissioning Status, Install Date, Punch List Notes
• Sustainability attributes (Low VOC, Recycled Content %)
• Web links (URL) to manuals or product pages

How to set them up correctly:

• Manage > Project Parameters > Add
• Use a clean naming convention (e.g., “QA_NeedsReview”, “Spec_Section”, “Asset_ID”)
• Choose Instance for element-specific values; Type when the value should be identical across all instances of a type
• Pick the right data type: Yes/No for filters, Text for labels, Integer/Number for counts and calculations, URL for links, Currency for costs
• Group parameters under Identity Data (or a dedicated group) for discoverability
• Bind only to the categories that truly need the data; use Multi-Category when the value spans many categories

Using the data:

• Schedules: Add the parameter as a field, sort/group, then filter blanks to find missing entries
• Quality views: Create view filters based on Yes/No or text values to color-code elements for review
• Templates: Bake parameters and related view filters into your project template for repeatable setup
• Dashboards: Create multi-category schedules for quick health checks (e.g., “QA_NeedsReview = Yes”)

Tagging and documentation:

• Project Parameters cannot be tagged. If you must tag it, define it first as a Shared Parameter, then add it to the project (and into the tag family) so it remains taggable and schedulable
• Keep a central “Parameter Register” (CSV/Excel) to track names, data types, categories, and who owns population

Interoperability tips:

• IFC: Map important parameters to IFC property sets using the IFC parameter mapping settings or a Pset mapping file
• COBie/Asset handover: Prefer Shared Parameters for required deliverables; align names and data types early
• Use consistent enumerations (e.g., New | Existing | Demo) to avoid post-export cleanup

Governance and performance:

• Don’t change data types mid-project; create a new parameter and migrate values if necessary
• Use Yes/No flags for review workflows—they’re lightweight and filter fast
• Avoid storing numeric values as text; you’ll lose sorting and calculations
• Use Global Parameters for geometric control; Project Parameters are for data
• Audit quarterly: run schedules to find blanks, outliers, and inconsistent spelling/casing

Quick wins to try today:

• QA_NeedsReview (Yes/No) bound to Multi-Category; create a color review view
• Spec_Section (Text) to group schedules and guide detailing priorities
• Asset_ID and Warranty_End (Date/Text) for turnover alignment
• URL_Manual to open product docs directly from the Properties palette
