• In 3D models, you can apply pressure loads only to surfaces.

• In 2D models, you can apply pressure loads to an edge or to a curve that is the boundary of one and only one surface.

• You cannot apply pressure loads to points.

• Pressure loads are independent of a coordinate system, so you do not need to select a coordinate system.

• When you apply a pressure load, Creo Simulate displays a load icon on the appropriate entities. The icon includes a vector that indicates the direction of the load. If the vector direction does not agree with what you thought you specified, review the dialog box and check the sign of the load value.
