conclass ConVoid Openings 1.7.06 – Automated MEP Opening Coordination for Autodesk® Revit® and IFC Models

ConVoid Openings 1.7.06 is a specialized Autodesk® Revit® add-in developed by conclass to automate the coordination of MEP openings. The software simplifies the traditionally labor-intensive process of creating, adopting, updating, and coordinating openings for building services (also known as builders’ work openings, penetrations, recesses, or provision for voids).

The 1.7.06 version is fully compatible with Autodesk Revit 2021 through 2027, representing one of the most recent updates to the software. ConVoid enables users to create openings based on all Revit and IFC elements of any category and linked model, with no specific model requirements to consider before starting the process. The software supports a wide range of use cases, including MEP openings, structural openings, and converting doors and windows to structural openings.

Primary Users

ConVoid Openings 1.7.06 is designed for architects, structural engineers, and MEP (Mechanical, Electrical, Plumbing) engineers who need to manage building service penetrations efficiently. It serves professionals who:

  • Coordinate builders’ work openings for MEP services across multiple disciplines

  • Automate the creation and updating of openings in walls, floors, and other structural elements

  • Work with linked Revit® models and imported IFC files from various consultants

  • Manage large-scale projects with thousands of openings without overwhelming manual effort

  • Ensure clash-free coordination between structural and MEP designs

Key Features & Capabilities

Automated Opening Creation and Updates

  • Clash-Based Generation: Automatically creates openings where any 3D element (ducts, pipes, cable trays) clashes with host elements (walls, floors, roofs)

  • Support for Multiple Element Types: Works with all Revit categories, including generic models, MEP services, and structural elements

  • Gap Management for Cable Trays: Creates openings even when cable trays are modeled to the exterior and interior surfaces of a host element without intersection

IFC and Linked Model Support

  • Direct IFC Integration: Converts IFC Provision for Voids directly to Revit openings

  • Linked Model Support: Works seamlessly with linked Revit models from other disciplines, enabling cross-discipline coordination

Parameter Transfer and Data Enrichment

  • Transfer Parameters from Host and Reference Elements: Enrich openings with information such as fire ratings, material information, and MEP system abbreviations in a single step

  • Parameter Value Renaming: Standardize naming conventions across projects using a built-in renaming feature or CSV import templates

  • Model Name Transfer: Built-in “Model Name” parameter for tracking which model generated each opening

Coordination and Quality Assurance

  • BCF Collaboration: Export and import BIM Collaboration Format (BCF) files for simplified issue tracking and approval processes between disciplines

  • Clash Detection: Built-in clash detection to identify and resolve conflicts before construction

  • Change Tracking: Logs all changes to openings for transparency and accountability

Annotation and Reporting

  • Smart Tagging: Automatically tag openings in 2D plans

  • Plan Checking: Review and validate openings before coordination sign-off

  • Excel Export: Export opening data for external reporting or quantity take-offs

Advanced Control Options

  • Polygonal Openings: Manual placement of polygonal openings with 3 to 12 sides, available in both horizontal and vertical orientations

  • Single Openings per Host: Option to create separate openings for each host element when a service penetrates multiple layers (e.g., insulation and concrete wall layers)

  • Filter-Based Workflows: Create and manage filters to process specific parts or levels of a project

What’s New in ConVoid Openings 1.7.06

While specific changelog details for version 1.7.06 are limited, the release represents ongoing development and refinement of the ConVoid platform. Key aspects of the current version include:

Extended Compatibility

  • Revit 2027 Support: Version 1.7.06 is compatible with the latest Revit 2027 release, in addition to Revit 2021 through 2026

Proven Performance for Large Projects

  • Scalability: Successfully used in projects with up to 35,000 openings in a single model

  • Optimized Performance: Recommended workflow for large models involves creating and updating openings step by step, focusing on selected parts or levels of the building

No Model Requirements

  • Flexible Input: Supports all Revit and IFC elements regardless of category, with no specific model preparation requirements

  • Maximum Distance Consideration: Note that elements located beyond 10 miles/16 kilometers from the internal origin may affect accurate placement
