Class: Door

BIM. Door

Defines a parametric door opening within a building element.

A door provides a portal opening in a wall between two spaces or between a space and the outside. Its opening typically sits on or near the floor level and is around 2100mm (7') high in order to fit a 2040mm (6'8") door.

Doors differ from windows and other apertures in that they offer a means of egress and access into and out of a space. Whilst you can model a doorway using other aperture types such as a void, this will not yield the correct information when generating door schedules or performing analysis that needs to know specifically about doors. Thus, any aperture that in intended for people to move through should be added as a door.

:number

_openFraction

Stores the fraction that the aperture is currently open.

The effect of this will vary between different aperture types, and very probably in unimaginable ways by externally developed classes. Thus, it is included as a private property and exposed through the getOpenFraction getter/setter which can be overridden.

:PD.ALIGN

alignment

Defines the alignment of the aperture within its host surface, defaults to bottom-left corner.

This property determines how the aperture's position offsets are interpreted relative to its host surface. The default is to align the aperture's bottom-left corner with the corresponding corner of the host surface, but other options allow it to be aligned centrally or to the right/top edges.

Type
Inherited From:
Overrides:
:boolean

alwaysShowInPlan

Whether or not to always show this aperture in plan-section view.

When set, this window will always be shown within a plan-section view even if it does not actually cross the horizontal cutting plane.

Inherited From:
Overrides:
: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.

Type
  • string
Inherited From:
Overrides:
:string

displayName <readonly>

The name to display for this class within the user interface.

Type
  • string
Inherited From:
Overrides:
:BIM.ENTITY

entityType <readonly>

Defines the type of BIM entity this class represents.

This value is used by the PD.Registry for grouping elements and matching components. The base implementation simply references this.constructor.getEntityType() so that only a static method needs to be added to subclasses.

The actual shape of the hole to cut through its host element.

This is a crucial part of the aperture that gives its shape and is used as the basis for interactive selection when the model is viewed in 3D. It is automatically updated whenever the host junction or element changes. The positions of its vertices are given in absolute world coordinates, but will/must always be in the same virtual plane as its host surface.

Type
Inherited From:
Overrides:
:string

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.

Type
  • string

The meaning of this value depends on the current alignment property value. For TOP and BOTTOM alignments, it is the distance of the aperture from the respective horizontal edge of the host surface. For MIDDLE alignments, it is the minimum allowable offset from both TOP and BOTTOM edges.

Type
  • number
Inherited From:
Overrides:
:number

openFraction

Defines the fraction of the aperture that is open.

This value will affect different aperture types in different ways, and very likely in some completely unexpected ways with externally developed aperture types. It is a value that ranges from 0 to 1 for most kinds of aperture, and -1 to 1 for some doors that can open two ways.

Type
  • number
Inherited From:
Overrides:
:BIM.OPENING

openingType

Defines the type of opening, defaults to a plain void.

This property determines the gbXML nature of the aperture, whether it is a void, window, door, panel or feature. The assigned aperture type component must be compatible with this gbXML opening type.

Type
Inherited From:
Overrides:
:THREE.Vector2

pos

The actual position of the aperture relative to its host surface.

This gives the final calculated relative position of the aperture. These may be different to preferred offsetHor and offsetVer values as the aperture may need to be modified if its size would extend beyond the extents of the surface it belongs to. Preference is always given to maintaining the size and shape of the aperture, with its position adjusted first to make it fit.

Type
  • THREE.Vector2
Inherited From:
Overrides:

:Array.<PD.Element>

shadingComponents

Stores a list of associated shading components.

These components are typically external shading devices such as brise soleil, louvers, overhangs, fins, awnings, canopies, shutters, or other similar devices that are associated with the aperture.

Type
  • Array.<PD.Element>
Inherited From:
Overrides:
:THREE.Shape|null

shape

An optional 2D shape from which to generate the profile.

The bottom-left corner of this shape, or the minimum extents of its bounding box, should ideally start at the origin in order to be positioned accurately within the aperture's host surface(s).

shell

Stores the jamb surfaces of the aperture as well as any frame geometry.

This shell contains the internal surfaces of the aperture jambs, as well as any frame geometry that may be part of the aperture.

Type
Inherited From:
Overrides:
:PD.Polygon|null

sillProfile

The outline of the aperture when viewed in plan-section view.

This is also a crucial part of the aperture that gives the shape of the hole when viewed in plan-section view, and is used as the basis for interactive selection when in plan view. It is automatically updated whenever the host junction or element changes. The positions of its vertices are given in absolute world coordinates, but will/must always be in a horizontal plane located immediately below the aperture.

Type
Inherited From:
Overrides:
:THREE.Vector2

size

The size of the aperture within the plane of its host surface.

This gives the final calculated size of the aperture. This may be different from the preferred width and height values as the aperture may need to be modified if its size would extend beyond the extents of the surface it belongs to. Preference is always given to maintaining the size and shape of the aperture and adjusting its position first to make it fit. However, if the host surface is smaller than the preferred size, the actual size will be then reduced to fit.

Type
BIM.Aperture

addToExtrudedPolygon(polygon)

Inserts the aperture as a hole within the given polygon.

This method assumes that the polygon is extruded vertically by some amount and that the vertices are in an anti-clockwise order, when viewed from same side as its surface normal, with the first vertex being the bottom-left, the second being bottom-right and the third top-right, etc.

alignCoordsWithCurvedOpening(coords)

Aligns the given local coordinates to the curved opening of this aperture and returns the direct linear distance between left and right sides.

If this aperture is curved, and its curved path has been generated, this method will modify the given local coordinates so that the X-axis is aligned to the tangent of the curved opening, and the Y-axis is aligned to the normal of the curved opening. The Z-axis is not modified.

It also computes the distance between the left and right sides of the opening. If the aperture is planar, this is simply the size.x value. However, if the aperture is curved, this will be the linear distance between the start and end points of the curved aperture path.

Parameters:

computeSharedLocalCoordinates()

Sets up a shared local coordinate set for the given aperture.

As this returns shared local coordinates, you must assume that these computed settings are only valid when used within the method or function that called this method, or within any methods directly invoked by the calling method/function. If you try to update another aperture after calling this method, or use promises or await where that might happen, then there is a very real risk that something else may change them in the interim.

This method assumes that the update() method has already been called on the given aperture after any changes to it so that its core profile has already been computed.

The origin of the local coordinates is set to the bottom-left corner of the aperture opening profile. The U-axis is set to the direction of travel from the given junction to the next, and the V-axis to the normal to that direction. The W-axis is set to the normal of the path that the junction belongs to or, if it doesn't belong to a path, its own upVector.

NOTE: This method calls the generateSillProfile() method to compute the plan profile of the aperture, so you do not need to call it beforehand. When a level updates, it either calls this method or generateJambGeometry(), but never both.

Parameters:
Name Type Argument Description
level BIM.Level

The level to get section plane.
frameDepth number <optional>

The depth of the internal frame.
frameOffset number <optional>

The offset of the frame from the path line, defaults to zero.

generateSillProfile( [frameDepth] [, frameOffset])

Generates the horizontal profile of the aperture.

The horizontal profile is basically the shape of the sill of the aperture when viewed in plan. It is used for interactive selection in plan view, for generating plan-section holes in the host level's footprint and is extruded to generate the side and head jamb surfaces.

In a wall between two angled corners, the inside and outside surfaces may well be of different lengths, and both different from the path length the wall segment follows. This means that, if either side of the aperture is near one the corners, the inner aperture hole may be different from the outer aperture hole. This means that the sill may need additional vertices, as shown in the diagram below.

Internal Frames

The sill needs to adapt even further if it is to accommodate an internal frame. In such cases, it needs to know the frame offset from the path line and the frame depth. This allows it to ensure that the frame always abuts an area of side jamb that is perpendicular to the path line.

Thus, this method can be used by aperture type components to generate sill and jamb geometry that is compatible with their own frame dimensions and positions.
