Reference Information: Design Range Management

General Information

Converter for IFC supports standard and large design ranges, not small range.

When you create new content, you must specify the associated design range. Normal range is the default option and is sufficient in the majority of cases. For more information, see 3DEXPERIENCE Native Apps: Introducing Design Range Management.

At Import

Files are imported in the design range defined in the Design Limits tab in Me > Preferences. As a consequence:

Only that design range is taken into consideration, not those defined in the file, if any.
It is not possible to import assemblies containing different ranges, as only one design range is considered.
A warning is displayed in the work area and in the error file if the imported geometry is not compliant with the current design range.
Since Converter for IFC does not support small range, you are given the choice to import the file in normal range or to abort the import.
When either the small or large design range is not supported by the selected format, the data are imported in normal design range.

The following options in Me > Preferences are impacted by the design range management.

The resolution for Geometry quality enhancement is adapted to the current design range.
The Input tessellation parameter is not available.

At Export

The data are exported in the design range defined at their creation, even in the case of hybrid assemblies, not in the design range defined in the Design Limits tab in Me > Preferences.

Note: The export of small range part data is not supported. Messages are generated in the .err file.

For assemblies containing both normal and large ranges, the output contains the information about the largest range, but does not identify data in large range from data in normal range.

A warning message is displayed when exporting large range data, to remind you that the receiver may not be able to open it.
