About Visibility

The visibility status of entities is taken into account.

STEP elements listed by the STEP INVISIBILITY entity are created in the NoShow space. This applies to the high level entities:

• If a shell vertex is invisible but not the shell itself, the vertex will be visible in 3DEXPERIENCE.
• An exception is made for faces: When a solid or a shell is not declared in STEP as INVISIBLE (not listed by the INVISIBILITY entity), but all its faces are INVISIBLE, this solid or shell is created in the NoShow space.

The data to export can be defined by their visibility.

Show/NoShow options can be activated under Export, in the STEP Exchange section of the Preferences.

For visibility of instances, see also About The Structures (At Export).

The data to export may be:

• Visible entities placed in the Show space.
• Hidden entities placed in the NoShow space.
• Hidden entities placed in layers that are not visualized.

When Export also NoShow entities is not selected, only visible entities are exported to STEP.

When Export also NoShow entities is selected, all entities belonging to both the "Show" and the "NoShow" spaces are exported, the entities that are in the NoShow space being exported under the INVISIBILITY STEP entity.

When Export non-visualized layers is selected, all entities belonging to those layers are also exported. Those entities are not exported under the INVISIBILITY STEP entity.

Important: STEP export does not manage the visibility of instances of products. Hence, if an assembly contains instances in No Show: If all instances are in No Show, those instances and the corresponding product are not exported. If at least one instance is visible, the product is exported together with all its instances.
