The loads display options are set using the "Display settings" dialog box (ALT + X).
By default, the size of the graphical representation of the loads (punctual, linear or planar) is proportional to the intensity of the load (Fixed loads scale option is disabled).
Right clicking in the working area and selecting Loads auto-scale from the context menu displays the automatic scale of the loads. This is recommended for a better display of loads.
The loads can also be represented at a fixed scale. In this case, all loads have the same size regardless of their intensity. Thus, the smaller loads can be also visible in a model that contains large loads.
