Constraints on Entities
You can place displacement constraints on a variety of geometric entities including points, vertices, edges, curves, and surfaces.
You define a displacement constraint by selecting the appropriate geometric reference before or after opening the Constraint dialog box to indicate how Creo Simulate should apply the constraint.
The geometric entities you can constrain differ according to the model type and operating mode, as shown below:
Model Types
Constrainable Entities
3D
point, vertex (FEM only), edge/curve, surface
2D plane stress
point, edge/curve, surface
2D plane strain
2D axisymmetric
point, edge/curve, surface
