You can import and export planar and zonal cross-sections of part and assembly models that belong to the Neutral, Creo Elements/Direct, STEP, and JT file formats. The part and assembly models can contain single or multiple planar and zonal or a combination of planar and zonal cross-sections.

When you export part models to STEP, the offset cross-sections in the models are converted to a set of zones. When you export a part with zonal cross-sections, multiple cross-sections are created and added to the model views. The zonal cross-sections in the STEP files are imported as is to Creo.

The cross-sections of the part and assembly models that are imported and exported must be associated with combined states and can contain annotations. When you import and export the part and assembly models, the cross-sections transfer along with the combined states and annotations.

The following definitions and properties of the cross-sections are preserved during the import and export of part and assembly models:

When planar cross-sections are associated with combined states, the clipping directions of the cross-sections are transferred as a property of the combined states. When cross-sections reference combined states, you can change the setting of the clipping directions that are defined in the cross-sections to use the cross-sections for views that are set at 180 degrees from each other.

When you import the part and assembly models after an initial export, the cross-sections reimport retaining the following associations and settings:

The clipping direction of a planar cross-section is correctly applied for each combined state when two combined states are associated with a planar cross-section. One combined state uses the default setting of the clipping direction while the other combined state tries to reverse the clipping direction of the planar cross-section. However, the clipping direction re-imports as a property of each combined state and is correctly applied.
