Class: IFCPanel

BIM. IFCPanel

A core class for parametrically generating IFC panel geometry.

This class provides basic parameters for defining an IFC panel. Other classes can build in this infrastructure to define additional parameters and generate more detailed and specific parametric shapes.

Panels are used by doors and casement windows, and may optionally contain one or more internal glazed or recessed sub-panels. The layout or arrangement of sub-panels is governed by the BIM.PANEL enumerator.

A basic IFC panel defines the outer frame dimensions as well as mullion and transom sizes required to arrange and generate holes or recesses within a panel of a given dimension. This component can be used to generate panels of any width, depth or height, so the internal sub-panels will dynamically adapt in an attempt to maintain the set frame, mullion and transom sizes.

If the transom and mullion depths are both equal to the panel depth, then a monolithic panel will be created where the front and rear faces are a single flat plane with holes for each sub-panel. If the transom and mullion depths are different, then they will be created as separate prism components within the panel.

Members


:string

className <readonly>

The name of the subclass for this object instance.

This name must match the name of this class within the PD.Registry. Thus, the base implementation simply references this.constructor.getClassName() to ensure that this is always the case even for subclasses. As a result, there is rarely any need to override this method.

This property is used when copying, storing and exporting data for subclass instances to ensure that they are recreated as instances of the right class.

iconName <readonly>

The name of the SVG icon to associate with this object instance.

This name should match the name of the icon associated with this class within the PD.Registry. Thus, the default implementation simply references this.constructor.getClassName() to ensure that this is always the case, even for subclasses. However, you can override this property if you want a different icon dependant on other properties of the class instance, as shown in the example below.

// Overriding the icon name.

isLocked

Whether or not this component's parameters are fixed.

This property is used by the UI and framework to indicate that the component's parameters are fixed and therefore not editable. It is typically set by a 3rd-party manufacturer or supplier on products that they can only provide in one configuration.

For example, there is no point specifying a particular manufacturer's fridge and then adjusting its width to fit a hole in your cabinetry if that manufacturer cannot actually supply a fridge of that width.

Thus, when this property is true, you will not be able to edit the parameters, but you can always duplicate the component (or its configuration), but without the supplier details if you really do want to modify it.

Methods


adaptAndFitPanelData(panelData)

Adapts the shared panel data to fit the given panel size.

The same panel layout can be used to generate panels of any size or aspect ratio, such as different sized doors or window casements. Rather than modify the original values, a shared object is used to store a volatile copy of the panel layout data that ia adapted to fit the given size.

As this is a shared data object, you must use it immediately and only within the same method that computing it. This method will be called for every door that uses swinging, sliding or folding panels, so you cannot assume that the data won't change between if you try to use it at some stage without resetting.

Returns:

Returns the shared panel description data object.

hasMethod(component, methodName)

Determines if this component has a callable method with the given name.

This method is useful for checking if the component has a particular method before attempting to call it, thereby avoiding potential runtime errors. It is used within the framework to check for the presence of life-cycle methods in an element's type component before delegating them.

Parameters:
Name Type Description
component BIM.Component

The component to check.

methodName string

The case-sensitive name of the function/method to check for.

Inherited From:
Overrides:
Returns:

Returns true if the component is valid and has the function name as a method, otherwise false.

Type
boolean

isCompatibleWith(obj)

Determines if this component can be added to the given entity.

Whilst a small number of components may be compatible with multiple entity types, most components are designed to be used only by a specific entity type, and will not allow you to assign them to an incompatible entity.

Parameters:
Name Type Description
obj BIM.ENTITY | BIM.Entity

The entity type or object instance to check for compatibility with.

Inherited From:
Overrides:
Returns:

Returns true if the component can be added to the object, otherwise false.

Type
boolean

rebuild(element)

Rebuilds the geometry of this component ready for visualisation.

This is a placeholder method that should be overridden by subclasses to provide the necessary geometry generation logic for the component. Geometry is typically added to the host element's brep and/or shell based on its path.

Parameters:
Name Type Description
element BIM.Element

The element to rebuild.

Inherited From:
Overrides:
Returns:

Returns this component instance to support method chaining.

renderPanelInPlanSection(panelData, aperture, meshes, coords [, outline] [, no_infill])

Generates a plan-section view of the panel layout.

Parameters:
Name Type Argument Default Description
panelData object

The adapted panel dimensions.

aperture BIM.Aperture

The aperture to render.

meshes BIM.Meshes

The set of meshes to add geometry to.

coords PD.LocalCoordinates

The local coordinate system to use.

outline boolean <optional>
false

Don't draw in section when true.

no_infill boolean <optional>
false

Don't draw panel infill when true.


updateDynamicParameters(param, group)

Sets the dynamic parameter value and returns true if it changed.

Most subclasses don't need to override this method as it automatically detects changes and rebuilds the element/component and model when required. However, if you do need to add your own custom logic or intercept the return value, please read the following examples carefully and use whichever best suits your needs.

NOTE: When overriding this method, you may not want to call super.updateDynamicParameters(param, group) as the parent class may have added its own logic that may interfere with what you want to do. Instead, either use the static PD.Base.updateDynamicParametersOnHost method to check if the value changed, or base it on the third example which replicates the code in that static method.

Parameters:
Name Type Description
param PD.Parameter

The dynamic parameter that changed.

group PD.ParamGroup

The group that the dynamic parameter belongs to.

Inherited From:
Overrides:
Returns:

Returns true if the value actually changed.

getAndResetSharedPanelData() <static>

Retrieves a shared data object describing a panel configuration.

The same panel type instance can be used to generate window and door panels for many different apertures, each one with potentially different sizes and aspect ratios. Moreover, a single door aperture may have multiple swinging, folding or sliding panels, each at different angles and orientations. Some of these may be too small to accommodate the current frame, mullion and transom sizes, which then need to be reduced to fit the actual panel size.

Rather than modifying actual instance properties, this shared data object stores a temporary copy of all the data required to describe such a panel, which can then be dynamically adapted to fit a specific panel size. Also, as apertures can be dynamically resized at up to 60 times per second, a shared object is used to avoid unnecessary memory allocation and minimise garbage collection issues.

The data stored by this shared object should be considered highly volatile. Thus you should retrieve it, set its values and then use it, all within the same function or method. The obvious intention is that this object be passed around to other classes or functions during that process, but that should occur within the same higher level method, as shown in the example below.

Returns:

Returns a shared panel description object.

function generateDoorPanel(level, aperture) {

     if (aperture.panelComponent) {
