If the model nodes are not visible, turn on the appropriate layer in the Layers pane.
If you want to use a local coordinate system when setting the loads, first define and activate the local coordinate system.
Click one of the sub-menu items under (Boundary Conditions tab > Constraints and Loads panel > Loads). You can select either Point or Edge for a nodal load.
Select the Tools tab in the Project pane.
Select the nodes on the model where you want to set the load(s).
If setting a Point load, enter the force to be applied (Nodal force) and the allowed rotation (Nodal moment) for the X, Y, and Z directions.
If setting an Edge load, enter the force to be applied (Nodal force) in the X, Y, and Z directions.
Select Apply. The load should now be applied to the model.
Tip: You can apply the load in any arbitrary (non-global) direction by first setting up a local axis system at the node (see Step 2). If a local axis system is not specified, the load will be set globally.
