Use this dialog to:
•Show Velocity Vectors and Acceleration Vectors of a Point as you cycle the model.
•Find the exact X and Y coordinates of a Point relative to the XYPlane of the MechanismEditor.
•Find the exact x, y and z coordinates of a Point relative to xyaxes of the Part.
•Edit the x,y position of a Point that does not have ANY dimensions or constraints added to it with the PartEditor.
Edit a Point


There are three separators: •Show or Hide Vectors •Mechanism Coordinates (ReadOnly) •Point Coordinates (ReadWrite) 
Velocity and Acceleration Vector checkboxes The Velocity and Acceleration Vectors are exact and evaluated at each machine step using closedform algorithms. You have the option to show the same vectors that are calculated numerically with a simple difference algorithm. The numerical vectors are physically offset to the analytical vectors. If you show Velocity or Acceleration vectors, or both: •The vectors show, from the Point and only when the Point is moving relative to the MechanismPlane •The length of each vector is proportional to the Point's instantaneous Velocity and Acceleration. •The magnitude of each vector shows at the arrowhead of each vector. •The color (default) of the vectors are Velocity, Acceleration •See Edit menu > ApplicationsSettings > Graphics tab > Display colors  Velocity Vectors/Acceleration Vectors


Scope You can display the vectors that are calculated relative to the: •Local xyz axes  Mechanism Axes (default) •Global XYZ axes  MODEL AXES. Velocity Vector Options The Velocity vectors can show as one of:: •Magnitude of the Velocity (default) •X component of the motion •Y component of the motion •z Component of the motion 

To change the scale and length of the vectors, use the buttons in the FeedbackArea: •Click the up or down buttons below Vel. to edit the Velocity Vector •Click the up or down button below Accel. to edit the Acceleration Vector 
Mechanism Coordinates (ReadOnly)
The Point coordinates (X, Y, Z ) relative to the Origin of the MechanismPlane (and BasePart). The X, Y, Z dimensions are ReadOnly. BasePart and 0,0 XY Axes The Origin (0,0, 0) of the MechanismPlane is the intersection of the small X and Yaxes in the BasePart. 
Note: The Point coordinates (x , y) are relative to the Part's Origin. Its Origin is the startPoint of the CADLine Its Xaxis is in the direction from the startPoint of the CADLine to its endPoint. Lock and Edit Point's Position: ◉ Edit in PartEditor The Point remains free. You can edit it in the PartEditor. 

◉Lock and Edit here Use x and y datavalues to edit the (x , y) coordinates of the Point This is available ONLY if the Point is free of constraints and dimensions in the PartEditor If you use this option, you will not be able to edit it in the PartEditor.
