IFC Export User Guide

Source

Defines what to export, reference datum for the export process (optional) and build collections either temporary or stored in the database for reproducibility.

Load and Save IFC Export Window Settings

When an export transaction is completed and the IFC Export window is closed, the window settings are saved to a default file in the AVEVA_DESIGN_USER directory. The file is named ifcexport.expsav. When the IFC Export window is re-invoked, the system searches for this file and restores all but one of the IFC Export window values at the time of closing the IFC Export window.

Note:

The settings can be saved to any other file which might then be shared by a team of designers. This allows for consistency of export transactions.

Load and Reset

All the IFC Export window settings can be saved to a file, and reloaded into the IFC Export window.


Load	Use a file browser to select a previously created file to populate the IFC Export window fields. On loading a settings file, all the fields are repopulated except the field defining the destination file. This makes sure that the output location is stated.
Reset	Clears all fields and sets them to the system default values.

Source

Defines the elements for export. All elements for export are displayed in the element list.

Add

Adds elements to the element list.

Adds the current element.

CE Members

Adds the members of the current element.

Adds an element, specified explicitly in the text box above the Add drop-down list by name or reference number.

Current Selection

Adds the currently selected elements in the 3D view.

Current Collection

Adds the elements in the currently selected collection.

Note:

For export repeatability, it is recommended to build lists, either as shared (permanent) collections or as personal collections.

Drawlist

Adds the elements in the drawlist.

Claimlist

Adds the elements in the claimlist.

Element List

Displays all elements for export by type and name. The element list is constantly checked for duplicates to make sure that items are not exported more than once.


Clear	Right-click and select Clear to remove the currently selected element from the element list.
Clear list	Removes all elements from the element list.
Clear selection	Removes the currently selected elements from the element list.

Reference Datum

Often, different design systems use different orientation and positioning defaults. For example, a building might have its origin at one corner, and a principal axis parallel to a main wall. This might not be correct when the building is considered in the context of the whole project model.

This information is not transferred through the IFC file and must be communicated personally between the producer of the IFC file and its receiver.

This aspect is most relevant when importing models from a variety of sources to be aggregated into the single AVEVA E3D™ model with a uniform positioning and orientation system. Each IFC file might have a local origin and orientation which must be coordinated with the whole model.

Select the Use Reference Datum check box to relocate and re-orientate the model in AVEVA E3D™ in preparation for export to the target design system. The Reference Datum drop-down list becomes available.

In the Application Data World, a set of reference datum points (ZONEs) can be generated which are used to provide coordinate systems for transforming the exported model. Normally they are not editable (locked by default), but can be changed.

The actual reference datum names have a “secret” suffix, this is for security, so that the risk of name clashes is reduced.

Use the Reference Datum drop-down list to select an existing reference datum or to create a new one.

Properties

Modifies the properties of the currently selected reference datum.

Note:

The IFCGLOBAL Reference Datum is not modifiable (by default E0N0U0 / Y is N and Z is U). If accidentally deleted, it is regenerated.

Delete

Deletes the currently selected reference datum.
