Get a copy of this object.

If None, the properties will be duplicated with the same host.

faces_by_blk()[source]

Get all Faces in the model separated by their blk property.

This method will also ensure that any faces with Surface boundary condition are not duplicated in the result but are rather offset from the base face to ensure modifiers on opposite sides of interior Faces are accounted for. Furthermore, this method also ensures that any static interior sub-faces (with Surface boundary condition) only have one of such objects in the output lists.

Returns:

  • faces: A list of all faces without a unique modifier_blk.

  • faces_blk: A list of all opaque faces that have a unique modifier_blk.

Return type:

A tuple with 2 lists

generate_exterior_aperture_sensor_grid(dimension, offset=0.1, aperture_type='All')[source]

Get a radiance SensorGrid generated from all exterior Apertures of this Model.

This will be None if the Model has no exterior Apertures.

Parameters:

  • dimension – The dimension of the grid cells as a number.

  • offset – A number for how far to offset the grid from the base aperture. Positive numbers indicate an offset towards the exterior while negative numbers indicate an offset towards the interior, essentially modeling the value of sun on the building interior. (Default is 0.1, which will offset the grid to be 0.1 unit from the aperture).

  • aperture_type –

    Text to specify the type of Aperture that will be used to generate grids. Window indicates Apertures in Walls. Choose from the following. (Default: All).

    • Window

    • Skylight

    • All

Returns:

A honeybee_radiance SensorGrid generated from the exterior Apertures of the model. Will be None if the Model has no exterior Apertures.

generate_exterior_face_sensor_grid(dimension, offset=0.1, face_type='Wall', punched_geometry=False)[source]

Get a radiance SensorGrid generated from all exterior Faces of this Model.

The Face geometry without windows punched into it will be used. This will be None if the Model has no exterior Faces.

Parameters:

  • dimension – The dimension of the grid cells as a number.

  • offset – A number for how far to offset the grid from the base face. Positive numbers indicate an offset towards the exterior. (Default is 0.1, which will offset the grid to be 0.1 unit from the faces).

  • face_type –

    Text to specify the type of face that will be used to generate grids. Note that only Faces with Outdoors boundary conditions will be used, meaning that most Floors will typically be excluded unless they represent the underside of a cantilever. Choose from the following. (Default: Wall).

    • Wall

    • Roof

    • Floor

    • All

  • punched_geometry – Boolean to note whether the punched_geometry of the faces should be used (True) with the areas of sub-faces removed from the grid or the full geometry should be used (False). (Default:False).

Returns:

A honeybee_radiance SensorGrid generated from the exterior Faces of the model. Will be None if the Model has no exterior Faces.

static reset_resource_ids_in_dict(data, add_uuid=False, reset_modifiers=True, reset_modifier_sets=True)[source]

Reset the identifiers of radiance resource objects in a Model dictionary.

This is useful when human-readable names are needed when the model is exported to other formats like Rad and the uniqueness of the identifiers is less of a concern.

Parameters:

  • data – A dictionary representation of an entire honeybee-core Model. Note that this dictionary must have ModelRadianceProperties in order for this method to successfully edit the radiance properties.

  • add_uuid – Boolean to note whether newly-generated resource object IDs should be derived only from a cleaned display_name (False) or whether this new ID should also have a unique set of 8 characters appended to it to guarantee uniqueness. (Default: False).

  • reset_modifiers – Boolean to note whether the IDs of all modifiers in the model should be reset or kept. (Default: True).

  • reset_modifier_sets – Boolean to note whether the IDs of all modifier sets in the model should be reset or kept. (Default: True).

Returns:

A new Model dictionary with the resource identifiers reset. All references to the reset resources will be correct and valid in the resulting dictionary, assuming that the input is valid.
