[[visual3d:documentation:visual3d_signal_types:used_process#why_filter_the_analog_vs_force_data|however, we do not recommend filtering the force/cofp/freemoment signals.]] ===== modify_force_platform_parameters command dialog ===== it is also possible to modify force platform parameters via the graphical interface's dialog located in visual3d's force menu. the dialog provides you with an overview of all the current force platform parameter values and allows you to edit and save these values. amti4.png
