A material in IFC represents a physical material, such as timber, steel,
|

concrete, aluminium, etc. It may also contain physical properties used

for structural or lighting simulation. Note that unlike the computer
|
||||
graphics industry, a material by itself does not define any colour or

lighting information. Colours in IFC are known as "styles", and an IFC

material may or may not have any style information associated with it.

See ifcopenshell.api.style for more information.

A material is typically given a code name which is used by architects in

steel to be used in structural simulations.

category is critical to allow model recipients to make simple queries

standardised category naming of all materials, this type of query

'glass', 'gypsum', 'plastic', and 'earth'. The user is allowed to

specify their own category instead if none of these categories are

IFC allows you to state that objects are made out of multiple materials.
|
||||
These are known generically as material sets, but may also be called
|
||||
layered materials, composite materials, or other names in software.
|
||||
|
||||
There are three types of material sets:
|
||||
|
||||
- A layer set, used for layered construction such as walls, where the
|
||||
element is parametrically made out of extruded layers, each layer
|
||||
having a thickness defined. Even though this is known as a layer
|
||||
"set" it is still recommended to use it for all standared layered
|
||||
construction as it describes the intent of the element to be layered
|
||||
construction and thus can be used for parametric editing.
|
||||
- A profile set, used for profiled construction such as beams or
|
||||
columns, where the element is parametrically made out of one or more
|
||||
extruded profiles, where each profile may be parametric from a
|
||||
standard section (e.g. standardised steel profile) or an arbitrary
|
||||
shape (e.g. cold rolled sections, or skirtings, moldings, etc). Note
|
||||
that even though this is called a profile "set", it should still be
|
||||
used even if there is only a single profile. This is not available in
|
||||
IFC2X3.
|
||||
- A constituent set, used for arbitrary composite construction where
|
||||
the object is made out of multiple materials. The constituents may be
|
||||
explicitly defined via a shape, such as a window where the frame
|
||||
geometry is made from one material and the panel geometry is made
|
||||
from another material. Alternatively, the constituents may be
|
||||
represented in terms of percentages, such as in mixtures like
|
||||
concrete where there might be a percentage constituent of cement and
|
||||
another percentage constituent of binder. This is not available in
|
||||
IFC2X3.
|
||||
|

There is also a fourth material set known as a material list, which is a

legacy type of set used by IFC2X3. It should not be used on IFC4 and

"""Assigns a material to a product
|
||||
|
||||
When a material is assigned to a product, it means that the product is
|
||||
made out of that material. In its simplest form, a single material may
|
||||
be assigned to a product, meaning that the entire product is made out of
|
||||
that one material. Alternatively, a material set may be assigned to a
|
||||
product, meaning that the product is made out of a set of materials.
|
||||
There are three types of sets, including layered construction, profiled
|
||||
materials, and arbitrary material constituents. See
|
||||
ifcopenshell.api.material.add_material_set for details.
|
||||
|
||||
Materials are typically assigned to the element types rather than
|
||||
individual occurrences of elements. Individual occurrences would then
|
||||
inherit the material from the type.
|
||||
|
||||
If the type has a material set, then the geometry of the occurrences
|
||||
must comply with the material set. For example, if the type has a
|
||||
constituent set, then it is expected that all occurrences also inherit
|
||||
the geometry of the type, which is made out of those constituents.
|
||||
Alternatively, if the type has a layer set, then all occurrences must
|
||||
have geometry that has a thickness equal to the sum of all layers. If a
|
||||
type has a profile set, then all occurrences must has the same profile
|
||||
extruded along its axis.
|
||||
|
||||
For layers and profiles assigned to types, the occurrences must be
|
||||
assigned an IfcMaterialLayerSetUsage or an IfcMaterialProfileSetUsage.
|
||||
This allows individual occurrences to override the layered or profiled
|
||||
construction offset from a reference line.
