measure modify pt2pt

Allows you to modify an existing point-to-point measure.

This is a predefined measure that lets you capture and investigate kinematic characteristics of a point relative to another point, such as the relative velocity or acceleration. For example, you can use a point-to-point measure to calculate the global y-component of distance between any two specified markers.

You can also obtain point-to-point characteristics for geometric vertices. When you select vertices for the markers, Adams/View automatically creates a marker at each vertex and uses it in the point-to-point measure.

Format:

 

measure modify pt2pt
measure_name=	existing point-to-point measure
new_measure_name =	new name for the measure
component=	coordinate_component
motion_rframe=	existing marker
coordinate_rframe=	existing marker
characteristic=	measure_pt2pt_characteristic
from_point=	existing marker
to_point=	existing marker
legend =	string
create_measure_display=	boolean
comments =	string

Example:

 

measure modify pt2pt
measure_name=	.model_1.mea_pt2pt_1 &
new_measure_name =	.model_1.mea_pt_to_pt &
to_point=	.model_1.part_3.marker_4 &
characteristic =	"translational_displacement" &
component =	"mag_component" &
coordinate_rframe =	.model_1.ground.marker_10&
comments=	"point 2 point measure to capture the translational displacement of point marker_3" &
create_measure_display =	yes

Description:

 

Parameter	Value Type	Description
measure_name	Existing point-point measure	Specifies the name of an existing point-to-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	Translational_displacement, Translational_velocity, Translational_acceleration, Angular_velocity, Angular_acceleration	Specifies the kinematic characteristic to be measured. The values you enter next in the command depend on whether you select a translational or angular characteristics.
from_point	Existing Marker	Enter the marker or point from which to measure.
to_point	Existing Marker	Enter the marker or point to which 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:

The point-to-point kinematic characteristics that you can measure are shown in the table below.

 

The object:	Has the measurable characteristics:
Two markers	• Translational displacement • Translational velocity • Translational acceleration • Angular velocity (not available when creating a point-to-point measure from the Main toolbox) • Angular acceleration (not available when creating a point-to-point measure from the Main toolbox)
