Point Position & Vectors
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 XY-Plane of the Mechanism-Editor.
•Find the exact x, y and z coordinates of a Point relative to x-y-axes of the Part.
•Edit the x,y position of a Point that does not have ANY dimensions or constraints added to it with the Part-Editor.

There are three separators: •Show or Hide Vectors •Mechanism Coordinates (Read-Only) •Point Coordinates (Read-Write) |

Velocity and Acceleration Vector check-boxes The Velocity and Acceleration Vectors are exact and evaluated at each machine step using closed-form 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 Mechanism-Plane •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 > Applications-Settings > 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 Feedback-Area: •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 (Read-Only)
|
The Point coordinates (X, Y, Z ) relative to the Origin of the Mechanism-Plane (and Base-Part). The X, Y, Z dimensions are Read-Only.  Base-Part and 0,0 XY Axes The Origin (0,0, 0) of the Mechanism-Plane is the intersection of the small X- and Y-axes in the Base-Part. |
|
Note: The Point coordinates (x , y) are relative to the Part's Origin. Its Origin is the start-Point of the CAD-Line Its X-axis is in the direction from the start-Point of the CAD-Line to its end-Point. Lock and Edit Point's Position: ◉ Edit in Part-Editor The Point remains free. You can edit it in the Part-Editor. |
|
◉Lock and Edit here Use x and y data-values to edit the (x , y) coordinates of the Point This is available ONLY if the Point is free of constraints and dimensions in the Part-Editor If you use this option, you will not be able to edit it in the Part-Editor. |
