Editing MicroMVDs for exchange requirements/Element classes MicroMVD

{{Template:MVD_Documentation}}
The following [[Using MicroMVDs for exchange requirements|MicroMVD]] vocabulary can be used to ensure [[Industry Foundation Classes (IFC)]] elements belong to the correct IFC class.

<pre>
Feature: Element classes

In order to correctly identify objects
As any interested stakeholder filtering objects for a particular purpose
All IFC elements must belong to the appropriate IFC class

Scenario: Receiving a file
 * The IFC file "{file}" must be provided
 * IFC data must use the {schema} schema

Scenario: Ensure all IFC type elements use the correct IFC class
 * The element {guid} is an {ifc_class}
 * The element {guid} is an {ifc_class} only
 * The element {guid} is further defined as a {predefined_type}
 * The element {guid} should not exist because {reason}
</pre>

You can fill out the variables using the guide below.

|-
| <code>{file}</code>
| project.ifc
| The filename or path to any IFC file.
|-
| <code>{schema}</code>
| IFC4
| The schema version. At the moment, these are likely to be either IFC4 or IFC2X3.
|-
| <code>{guid}</code>
| 28q3AgmxP5cepIweO5Of$o
| This is a 22 character GlobalId for a particular IFC element.
|-
| <code>{ifc_class}</code>
| IfcWall
| This case insensitive text value must correspond to the full name of an IFC class.
|-
| <code>{predefined_type}</code>
| BEAM
| This case insensitive text value must correspond to the predefined type of an IFC class, or a custom object type.
|-
| <code>{reason}</code>
| we don't need it
| You can write anything here to describe any reason.

| For import, opening an IFC does not retain any element class information. Linking IFCs do retain this information. For export, some Revit family categories have restrictions on which element classes they can be exported to, and the user cannot override it.
