measure modify point

Allows you to modify an existing point measure.

This is a predefined measure that lets you capture and investigate Characteristics of a point, such as its location relative to the global coordinate system or the sum of forces acting on it.

For example, you can use point measures to resolve a force at a specific location on a flexible body, or you can determine the acceleration of the end marker of a pendulum with respect to the ground reference frame.

Format:

measure modify point
measure_name =	existing point measure
new_measure_name =	new name for measure
component =	coordinate_component
motion_rframe =	existing marker
coordinate_rframe =	existing marker
characteristic =	measure_point_characteristic
point =	existing marker
legend =	string
create_measure_display =	boolean
comments =	string

Example:

measure modify point &
measure_name =	.model_1.mea_point_1 &
new_measure_name =	mea_my_point &
point =	.model_1.part_3.marker_4 &
characteristic =	" total_force_on_point " &
component =	"mag_component" &
coordinate_rframe =	.model_1.ground.marker_10&
comments =	"point measure to capture the total force of point marker_3" &
create_measure_display =	yes

Description:

Parameter	Value Type	Description
measure_name	Existing point measure	Specifies the name of an existing point measure to be modified.
New_measure_name	New name for the measure	Specifies the new name for the measure. You can use this name later to refer to this measure.
component	X_component, Y_component, Z_component, Mag_component, R_component, Rho_component, Theta_component, Phi_component	Specifies the component in which you are interested. The components available depend on the coordinate system.
motion_rframe	Existing Marker	Specifies existing marker
coordinate_rframe	Existing Marker	Specifies existing marker
characteristic	Total_force_on_point, Total_torque_on_point, Total_force_at_location, Total_torque_at_location, Translational_deformation, Angular_deformation_velocity, Translational_deformation_velocity, Translational_displacement, Translational_velocity, Translational_acceleration, Angular_velocity, Angular_deformation, Angular_acceleration	Specifies the kinematic and characteristic to be measured.
point	Existing Marker	Enter the marker or point to measure.
legend	String	Specifies the text that will appear in the top of the measure window.
comments	String	Specifies any comments on this measure.
Create_measure_display	Yes/no	Specifies yes if you want to display a strip chart of the measure.

Extended Definition:

Point Characteristics You Can Measure

The characteristics of markers that you can measure are shown in the table below. All types of markers have the same measurable characteristics, but markers on flexible bodies have additional characteristics for deformation.

The object :	Has the measurable characteristics:
Markers on a rigid body, point mass, or flexible body	■total_force_on_point ■total_torque_on_point ■total_force_at_location ■total_torque_at_location ■translational_displacement ■translational_velocity ■translational_acceleration ■angular_velocity ■angular_acceleration
Markers on flexible body	■angular_deformation ■angular_deformation_velocity ■angular_deformation_acceleration ■translational_deformation ■translational_deformation_velocity ■translational_deformation_acceleration
