Void marking shouldn't take hours

MEP engineers spend countless hours on a task that should be automatic. We built a better way.

Without MEPOpeningMarker

Manual void marking is the bottleneck every MEP team knows too well.

  • Hours spent manually identifying intersections
  • Missed openings leading to costly on-site rework
  • Inconsistent void sizes across the project
  • Tedious coordination between disciplines

With MEPOpeningMarker

Automatic detection of every MEP intersection with walls and structural frames — in active and linked documents.

  • All intersections detected in seconds
  • Zero missed openings, zero rework
  • Consistent, rule-based void sizing with configurable offsets
  • One-click execution for the entire project

Everything you need to automate voids

Built specifically for MEP professionals who value precision and efficiency.

Smart Intersection Detection

Automatically detects pipes, ducts, and cable trays intersecting with walls and structural frames using solid boolean operations.

Rectangular & Round Voids

Choose between rectangular and round void shapes. Configure offsets, approximation steps, and discipline labels to match your project standards.

Linked Document Support

Detects intersections across both the active document and all linked Revit models. No need to bind links first.

Supports .NET Framework 4.8 (Revit 2021–2024) and .NET 8.0 (Revit 2025–2026). Seamless integration with your BIM workflow.
