Using groups to drive changes in ANSYS

SpaceClaim and ANSYS have full round-trip associativity. This means that changes to the model can be sent back and forth between SpaceClaim and ANSYS.

You can define groups to use as parameters and named selections. If the objects in the group are similar or related, then a property is created that can be used to change a parameter in ANSYS. For example, you could create a group of all faces that have the same offset and use this group to change the offset in ANSYS.

See Using groups and dimensions in ANSYS tutorial for hands-on examples.

NoteAnnotation placed on a design, drawing sheet, or 3D markup. Notes contain text or symbols that you insert and can be connected to geometry by a note leader.: Negative dimension values can invert the direction vector of SpaceClaim operations that they are associated with; this change is applied to the current and subsequent design point updates. As a result, when a Workbench input parameter is used as a driving dimension for a SpaceClaim geometry, negative dimension values may result in unexpected geometric changes.

Updating group parameters in ANSYS 13.0

In ANSYS 13.0, groups are instantly added to the Parameters group in Workbench. Changes to the group in SpaceClaim, such as renaming and deleting the group, are also immediately reflected in Workbench.

However, if you edit the dimension of a group parameter in SpaceClaim, the new value is not automatically updated in Workbench. You must click Update Parameters in the ANSYS group to push the change to Workbench. You can also send the change by saving the project or closing SpaceClaim. This means that if SpaceClaim is not running, you know that the parameters are up-to-date.

Using driving dimensions in ANSYS

You can create driving dimension groups in SpaceClaim and use them to change key dimensions in ANSYS. Just click on the part in the structure tree in ANSYS and find the CAD Parameters section in the Details panel. Change a value and run the analysis again to see its affect. You can use Update to send the new values back to SpaceClaim.

• Creating a driving dimension with Pull (offset)

• Creating a driving dimension with Move (translation or rotation)

• Creating a driving dimension with the Select tool (round radius and distance between offset faces)
