Force Load—Generative Design
You can create force loads on surfaces in your model.
To Define a Force Load
1. Click > 
Force. The Force Load dialog box opens.
Force. The Force Load dialog box opens.2. Specify a name for the load, or use the default name. Optionally click the color swatch adjacent to the Name box to change the color of the icon, the distribution, or the text displayed for the load.
3. Select a surface to which you want to apply the force load. Your selection appears in the References collector.
4. The default coordinate system of the model is the reference coordinate system and is displayed in the Coordinate system collector. If the model does not have a default coordinate system then the 
button is not available and the Coordinate system collector is empty. You can select any coordinate system, or create a UCS (user coordinate system).and designate it as the default coordinate system.

◦ Magnitude and direction—Specify the value of the unit vectors for direction by typing a value of 0, 1, or -1 in the X, Y, or Z field.
Alternatively click 
and select a linear edge or planar surface to specify the direction of the load. The value of the unit vector is displayed in the X, Y, or Z field.

◦ Directional components—Specify the components of the load for each coordinate direction X, Y, or Z. The resultant direction and magnitude of the force is determined from the values you specify for each coordinate. If you enter a positive value the force is applied in the same direction as the vector. If you use a negative value, the direction of the load opposes the vector.
6. Select units of force from the list or accept the default units.
7. Click OK to create the load and save it.
