Opening Parameters
Introduction
The opening families come with a range of parameters that are automatically set when running ConVoid. However, certain parameters should not be adjusted manually. The symbols below outline the suggested approach for managing these parameters:
The parameter should not be manually modified when the opening has been automatically placed by ConVoid.
The parameter can be manually modified.
The parameter should be modified using a ConVoid feature.
The parameter can be changed either manually or through a ConVoid feature.
Shared Parameters
All Shared Parameters can be found in the ConVoid family libary.
Dimensions Parameters
Total Dimensions
Parameters:
​
Total Diameter | Total Width | Total Height | Total Length | Total Depth
Description:
​
These parameters indicate the total dimensions of the opening.
Notes:
​
The total dimension is calculated by adding the dimensions of the reference element and the oversize of the opening. For example, the total width is calculated by summing the oversize left, width, and oversize right values.
Dimensions
Parameters:
​
Diameter | Width | Height | Length | Depth
Description:
​
These parameters represent the actual dimensions of the reference element, such as a duct or pipe
Notes:
Dimensions should not be modified when the opening has been placed automatically by ConVoid, as any changes made will be reset to match the reference element size during the next ConVoid run.
Oversize Dimensions
Parameters:
​
Oversize Left | Oversize Right | Oversize Back | Oversize Front | Oversize Bottom | Oversize Top
Description:
​
These parameters are used to increase or decrease the size of the opening.
Notes:
​
You can utilize these parameters to expand or reduce the opening's dimensions without causing alterations in the next ConVoid run. The oversize settings selected in your ConVoid filter might lead to marginally larger dimensions if rounded up.
Rotation
Parameters:
​
Rotation X Axis | Rotation Y Axis | Rotation Z Axis
Description:
​
These parameters are used to add a slope to your opening.
Notes:
You can achieve a combination of multiple rotations for the opening. To avoid generating sloped openings, you can disable this option in the ConVoid Settings.
Level and Elevation Parameter
Level Parameters
Parameters:
​
Base Level | Top Level
Description:
​
The openings are based on two levels, which are used to calculate the distance to the lower surface of the slab (SSL) and the distance to the upper surface of the slab (BB/S).
Notes:
​
We advise against adjusting these parameters through the Property Window, as the opening's location may vary. Instead, we recommend using the Level/Elevation feature in ConVoid for more dependable outcomes.
Offset of the opening to the Base Level
Parameters:
​
Offset Void - Base Level
Description:
​
The offset is set from the base level to the center of the opening.
Notes:
The parameter should not be manually adjusted when it has been automatically placed by ConVoid. If the opening was placed manually, use the Level/Elevation feature to set the elevation.
Distance to Level
Parameters:
​
Distance Void Lower Edge to Base Level | Distance Void Axis to Base Level | Distance Void Axis to Top Level | Distance Void Upper Edge to Top Level
Description:
​
These parameters indicate the distance between the opening and both the Base and Top Levels.
Notes:
​
This parameter is commonly used to display the distance to the lower and upper surfaces of slabs in a tag. To tag openings refer to the session Smart Tag.
Elevation - Project Base Point

Notes:
-
Visibility Parameters
Symbol Parameters
Parameters:
​
Symbol Top and Bottom | Symbol Back and Front | Symbol Right and Left
Description:
​
These parameters are used to change the symbol of the opening in a particular view.
Notes:
​
An overview of the symbols can be found here.
Display Symbol
Parameters:
​

Description:
​
If the parameter is enabled, the symbol will be displayed between the base and top levels. Otherwise, it will be visible only below the opening.
Notes:
-
Placeholder
Parameters:
​
Placeholder
Description:
​
By enabling this parameter, all symbols will be hidden in your plans, elevations, and other views.
Notes:
​
The parameter is commonly used to hide an opening. It will be set automatically if you join openings manually.
Offset Symbol
Parameters:
​

​
The vertical openings include three symbols in distinct areas, which can be utilized to display the appropriate symbol in a ceiling plan or floor plan.
Notes:
​
The vertical opening should be constrained to two different levels. Make sure to verify your cut plane offset and input the corresponding values into the parameter.
Control Parameter
Exclude Parameter
Parameters:
​
Exclude from conVoid
Description:
​
This parameter can be used in multiple ways. Enabling it will prevent any automatic changes to openings. Moreover, it can also be used to prevent ConVoid from creating an opening based on a host or reference element. To achieve this, simply enable the parameter in your host or reference element.

Location Parameter
Room Parameter
Parameters:
​
Room I/II: Name, Number, Level
Description:
​
These parameters need to be manually incorporated into the ConVoid Families, either by employing a project parameter or by directly integrating them within the family. You can locate these parameters in the Shared Parameter File. After adding them, ConVoid will automatically populate room values when placing or modifying openings.
Notes:
​
​ConVoid also supports rooms in a linked model. The parameter transfer is triggered when modifying openings. If the values remain empty, simply populate the room parameter with arbitrary text, and ConVoid will initiate the parameter transfer process.
