Data Transfer

Describes changes and new features in data transfer.

Newly supported file formats

Alias 2022 provides import support for the following file format versions:

For more information, see Alias supported file formats.

New Preserve Visual Orientation CATIA V5 export option

For the CATIA V5 format, we've added a Preserve Visual Orientation export option. When selected, the U and V parametric directions of the exported surfaces are adjusted so that the geometric orientation equals the visual orientation as defined in Alias. This option is on by default. To maintain the surface geometric orientation only, turn it off before exporting.

If you are using the AlToC5 command line utility, use the -k flag to turn this option off so that visual orientation is not preserved.

See CATIA V5 export options and AlToC5.

NX file import additions

Convert Specified Layers Only

We've added a new Convert Specified Layers Only NX import option so that you specify which layers in an NX file to open in Alias. After enabling this option, type the designated numbers of the target layers in the Specified Layer field. To do this, you can use a comma separated list, a layer number range, or a combination of both. The valid layer number range is between 1 and 256.

If you are using the NXToAlias command line utility, enable the Convert Specified Layers Only option with the -layerSelect flag. Specify the target layer numbers in a string contained by quotations, such as the following: -layerSelect "1,4,6";.

Optimize Geometry

A new Optimize Geometry option optimizes the CV layouts of the imported file for use in Alias.

If you are using the NXToAlias command line utility, you can enable this option by setting a new optimize geometry flag (-g)

See NX Import options and NXToAlias.
