type relates to the main material (or material combination)

<P>This enumeration defines the basic

configuration of the window type in terms of the number of window panels and
|

the subdivision of the total window. The window configurations are given for

windows with one, two or three panels (including fixed panels) as shown in Figure 171.</P>
|

<P>Windows which are subdivided into more than three panels have to be

defined by the geometry only. The type of such windows is USERDEFINED.</P>

|
||
|
||
<p><u>Definition from IAI:</u> This type definition is used to distinguish between different levels
|

of load grouping. It allows to differentiate between load groups, load cases, and load combinations.
|
||
Normally, these enumeration types shall be used in the following context:</p>
|
||
|
||
<ul>
|
||
<li>LOAD_GROUP groups instances of subtypes of <i>IfcStructuralAction</i>. It shall be used as a
|
||
container for loads grouped together for specific purposes, e.g. loads which are part of a
|
||
special load pattern.</li>
|
||
<li>LOAD_CASE groups LOAD_GROUPs and instances of subtypes of <i>IfcStructuralAction</i>.
|
||
It should be used as a container for loads with the same origin.</li>
|
||
<li><s>LOAD_COMBINATION_GROUP is an intermediate level between LOAD_CASE and LOAD_COMBINATION.
|
||
The purpose of this level is to provide a factor with which one or more LOAD_CASEs occur in a
|
||
LOAD_COMBINATION. This factor cannot be specified directly at the load case if the load case
|
||
is meant to occur in more than one combination with different factors.</s><br>
|
||
This intermediate level is obsolete. Instead, </li>
|
||
<li>LOAD_COMBINATION is used to group load cases which act together into a load combination.</li>
|
||
<li>USERDEFINED: A grouping level which does not follow the standard hierarchy of load group types.</li>
|

<li>NOTDEFINED: The grouping level is not yet known.</li>

<p><i>IfcGeometricProjectionEnum</i> defines the various representation types that can be semantically distinguished. Often different levels of detail of the shape representation are controlled by the representation type.
|
||
</p>
|
||
<ul>
|
||
<li>GRAPH_VIEW:
|
||
Geometric display representation that shows an abstract, often 1D
|
||
element representation, e.g. representing a wall by its axis line.</li>
|
||
<li>SKETCH_VIEW:
|
||
Geometric display representation that shows an abstract, often 2D
|
||
element representation, e.g. representing a wall by its two foot print
|
||
edges, surpressing any inner layer representation.</li>
|
||
<li>MODEL_VIEW:
|
||
Geometric display representation that shows a full 3D element
|
||
representation, e.g. representing a wall by its volumetric body.</li>
|
||
<li>PLAN_VIEW:
|
||
Geometric display representation that shows a full 2D element
|
||
representation, the level of detail often depends on the target scale,
|
||
e.g. representing a wall by its two foot print edges and the edges of
|
||
all inner layers. The projection is shown in ground view as seen from
|
||
above.</li>
|
||
<li>REFLECTED_PLAN_VIEW:
|
||
Geometric display representation that shows a full 2D element
|
||
representation, the level of detail often depends on the target scale,
|
||
e.g. representing a wall by its two foot print edges and the edges of
|
||
all inner layers. The projection is shown in ground view as seen from
|
||
below.</li>
|
||
<li>SECTION_VIEW:
|
||
Geometric display representation that shows a full 2D element
|
||
representation, the level of detail often depends on the target scale,
|
||
e.g. representing a wall by its two inner/outer edges and the edges of
|
||
all inner layers, if the element is cut by the section line.</li>
|
||
<li>ELEVATION_VIEW:
|
||
Geometric display representation that shows a full 2D element
|
||
representation, the level of detail often depends on the target scale,
|
||
e.g. representing a wall by its bounding edges if the element is within
|
||
an elevation view.</li>
|
||
<li>USERDEFINED:
|
||
A user defined specification is given by the value of the <i>UserDefinedTargetView</i>
|
||
attribute.</li>
|
||
<li>NOTDEFINED:
|
||
No specification given.</li>

IFC2x3 CHANGE This concept was initially introduced in IFC 2.0 as <i>IfcModifiedFlag</i> of type BINARY(3) FIXED and has been modified in R2x to an enumeration. It was initially introduced as a first step towards providing facilities for partial model exchange from a server as requested by the IFC implementers. It is intended for use primarily by a model server so that an application can identify the state of the object.

5269;IfcChangeActionEnum;"<epm-html>
|
||
|
||
<p><i>IfcChangeActionEnum</i> identifies the type of change that might have occurred to the object during the last session (for example, added, modified, deleted). This information is required in a partial model exchange scenario so that an application or model server will know how an object might have been affected by the previous application. Valid enumerations are:</p>
|
||
|
||
<ul>
|
||
<li>NOCHANGE: Object has not been modified.</li>
|
||
<li>MODIFIED: A modification to the object has been made by the user and application defined by the LastModifyingUser and LastModifyingApplication respectively.</li>
|
||
<li>ADDED: The object has been created by the user and application defined by the OwningUser and OwningApplication respectively.</li>
|
||
<li>DELETED: The object has been deleted by the user and application defined by the LastModifyingUser and LastModifyingApplication respectively.</li>
|
||
<li>NOTDEFINED: The change action is not known or has not been defined.</li>
|
||
</ul>
|
||
|
||
<p>Consider Application A will create an IFC dataset that it wants to publish to others for modification and have the ability to subsequently merge these changes back into the original model. Before publication, it may want to set the <i>IfcChangeActionEnum</i> to NOCHANGE to establish a baseline so that other application changes can be easily identified. Application B then receives this IFC dataset and adds a new object and sets <i>IfcChangeActionEnum</i> to ADDED with Application B defined as the OwningApplication. Application B then modifies an existing object and (re)defines the LastModifiedDate to the time of the modification, LastModifyingUser to the <i>IfcPersonAndOrganization</i> making the change, and sets the LastModifyingApplication to Application B. When Application A receives this modified dataset, it can determine which objects have been added and modified by Application B and either merge or reject these changes as necessary. Consequently, the intent is that an application only modifies the value of <i>IfcChangeActionEnum</i> when it does something to the object, with the further intent that a model server is responsible for clearing the <i>IfcChangeActionEnum</i> back to NOCHANGE when it is ready to be republished.</p>
