add_indoor_shade(shade)

Add a Shade object to be added to the indoors of this object.

Indoor Shade objects can be used to represent furniture, the interior portion of light shelves, the interior part of mullions, etc. For representing finely detailed objects like blinds or roller shades, it may be more appropriate to model them as materials assigned to Aperture properties (like Radiance materials or Energy constructions).

Parameters

shade – A Shade object to add to the indoors of this object.

add_indoor_shades(shades)

Add a list of Shade objects to the indoors of this object.

Parameters

shades – A list of Shade objects to add to the indoors of this object.

add_outdoor_shade(shade)

Add a Shade object to the outdoors of this object.

Outdoor Shade objects can be used to represent balconies, outdoor furniture, overhangs, light shelves, fins, the exterior part of mullions, etc. For representing larger shade objects like trees or other buildings, it may be more appropriate to add them to the Model as orphaned_shades without a specific parent object.

Parameters

shade – A Shade object to add to the outdoors of this object.

add_outdoor_shades(shades)

Add a list of Shade objects to the outdoors of this object.

Parameters

shades – A list of Shade objects to add to the outdoors of this object.

add_prefix(prefix)

Change the identifier of this object and child objects by inserting a prefix.

This is particularly useful in workflows where you duplicate and edit a starting object and then want to combine it with the original object into one Model (like making a model of repeated rooms) since all objects within a Model must have unique identifiers.

Parameters

prefix – Text that will be inserted at the start of this object’s (and child objects’) identifier and display_name. It is recommended that this prefix be short to avoid maxing out the 100 allowable characters for honeybee identifiers.

• detailed – Boolean for whether the returned object is a detailed list of dicts with error info or a string with a message. (Default: False).

Returns

A string with the message or a list with a dictionary if detailed is True.

check_self_intersecting(tolerance=0.01, raise_exception=True, detailed=False)
