To assign a uniform pressure load over a surface, use the following procedure.

1. Select the surfaces which will have the same point loads.
2. On the Surface ribbon tab, select the Pressure tool in the Loads group.
   
   The Add Surface Uniform Pressure Load dialog opens.
3. Select the Load group or case to which the load will be added from the drop-down list.
4. Type the Pressure to apply over the surface. Negative values may be used to reverse the direction of the load.
5. Select the Direction of the load from the drop-down list.
   • Global X / Y / Z – to apply loads parallel to the selected global axis.
   • Local x / y / z – to apply loads parallel to the local surface axis. Local x and y loads are in the plane of the surface.
6. Click OK. The dialog closes and the pressure load is applied to the selected surfaces.
