Based on a background interference check between current, linked IFC, and Revit files, conVoid creates openings, penetrations, and recesses with high accuracy. The quality optimization algorithm ensures that models can be used without model requirements. Openings can be created or converted based on all kinds of elements, even with complex geometry.

Use linked Revit and IFC models to run your process for creating openings. conVoid also supports the movement of linked models if they were placed in the wrong position.

conVoid supports all IFC Models, which can be linked to Revit.

​

• IFC MEP Models

• IFC Architectural Models

• IFC Structural Models

• IFC Provision for Void Models

• and other...

​

You can also work only with IFC models, without a need for a Revit Model.

conVoid supports all categories and element types, which are represented by a 3D-Element.

• Walls Slanted/Tapered

• Windows

There is no need to detect and filter clashes with other tools. conVoid has an advanced built-in clash detection, which will automatically find relevant clashes for creating openings.

Transfer Parameter Values from Reference- and Host-Elements to a selected Parameter of the openings, e.g., Fire Rating or Structural Usage. All Text Parameters which were been added to the Opening Family as a Project Parameter or Family Parameter can be selected as a Target Parameter.

conVoid uses a unique tracking algorithm to update openings throughout the whole designing process. Just use your current and external models, and conVoid will automatically inform you about any changes to keep your void coordination on track. Every detected change will be stored in a changelog, with an overview of the Location- and Parameter Changement.

To keep enough space between MEP- and Host-Elements, oversize the opening with a predefined offset.

Join openings into one single element based on a predefined distance of your choice. conVoid calculates the distance between the openings and joins them automatically.

Define the maximum diameter of circular openings. If an opening is greater than the predefined maximum diameter conVoid will change the shape of the opening from circular to rectangular.

Activate the [Cut with Host] option and conVoid will automatically cut the openings with the Host-Elements. Even a cut is set, conVoid will still detect changes and update the opening.

Activate the option [Lock with Host] to add constraints between opening and host-element. By changing the location or size of the host element, the opening adjusts automatically.

There is always the possibility to place openings manually. conVoid recognizes these openings and marks them as placeholders. As soon as a reference component penetrates this placeholder, conVoid automatically connects both elements and updates the opening in case of changes. 

Conclass developed highly adjustable Revit void families for everyone's needs. Following modifications can be done:

​

• Select between various 2D-Symbols to display the void in a view according to your needs

• Change rotation or slope of the voids

• Set a cut offset to the voids to keep enough space between the host and the reference element

• Get the distance between the upper or lower floor to void

• Activate a clash zone to check the distance to neighbor elements

Exclude Elements from the conVoid workflow to avoid that conVoid creates openings based on these elements. Structural Engineers can, for example, exclude structural elements like beams or walls where the MEP-Engineer should place no openings.

FEATUREs convoid manager

With the conVoid Manager, you get a complete overview of the current status of the openings. Review, approve and comment openings and share your results with other project participants.

conVoid supports BCF import and export, which allows you to share your results with other project participants. Use this feature to get your openings approved or commented on by the reviewer.

With the BCF Import- and Export function, you can run the issue and approval process on platforms like BIM Track, BIM Sync, BIMcollab, or other systems which support the Import- and Export of BCF Files. All added information, like comments, snapshots, titles, and approval status, can be imported and merged back to conVoid.

There is no need to create a BCF File for each opening. conVoid will automatically create a BCF for each opening. Furthermore, you can add snapshots and comments to the BCF.

Finding and saving a good viewpoint to let project participants zoom automatically to the opening by clicking on the BCF Issue is a time-consuming task. conVoid creates for each opening an optimal view.

Revit IDs can change during working cloud-based with BIM360. To still provide a readable ID of the openings which can be used for communication, conVoids creates for each opening a unique ID.

With conVoid Manager, you can add comments to each opening and share them with other project participants. Besides, you can create internal notes for each opening, just for your purpose.

Add a snapshot for each opening to capture certain situations. You can also edit the snapshot and add more information to it.

The conVoid Manager lists all parameters of the openings in a table and displays the rows in the respective status color of the openings. In addition, you can hide irrelevant parameters, which are then not output in the Excel export, for example.

Add color filters to the 2D and 3D views to highlight the different statuses of the openings. Define your status colors, which will be adopted in the conVoid Manager table and the active view.

Different filter options are provided to display a selective choice of openings in the table.

​

• Filter all openings in the active view

• Filter all openings which are not cut with the host-element

• Status Filter

• Filter openings with a specific parameter value

Export your results to an Excel and CSV file and make them available to other project participants.

Use the distance check to ensure that there is sufficient distance between the openings. A space is automatically created around the opening by activating the collision zone, which displays a warning if openings intersect.
