Simulation Feature Creation Methods
Simulation features are modeling features that you create while you are working in Creo Simulate—either native mode or FEM mode. These features exist only in your Creo Simulate session and are not visible in Creo Parametric unless you promote them. Each time you reenter the Creo Simulate environment, simulation features are saved and regenerated.
You can use simulation features to help define modeling entities, such as loads and constraints. You can create simulation features on your model in three different ways:
While in Creo Simulate, use the items on the Datum tab of the Refine Model tab to create datum axes, all three types of coordinate systems, datum points, datum curves, datum planes. Use items on the Regions tab of the Refine Model tab to create surface regions and volume regions.
While in Creo Parametric, use the items on the Datum group to create datum axes, coordinate systems, datum points, datum curves, and datum planes. Note that you cannot create surface or volume regions while in Creo Parametric.
Additionally, you can only create Cartesian coordinate systems. Even if you attempt to create cylindrical or spherical coordinate systems in Creo Parametric by using offsets, Creo Simulate treats the resulting coordinate system as Cartesian. To create true cylindrical or spherical coordinate systems, work from within Creo Simulate.
Use the icons on the toolbar to create datum axes, datum points, datum curves, or datum planes.
