Why use a Motion-Path Function-Block?


See also Motion-Path dialog-box


Motion-Path FB

To add a Motion-Path FB you select a sketch-path*. MechDesigner adds a Motion-Point to the sketch-element*. initially at its start-Point.

The motion-values at the input-connector to the Motion-Path FB specify the motion of the Motion-Point along the sketch-path..

Applications of a Motion-Path FB:

to define the path of a robot

to define the path of a chain or belt,

to define the motion for Ram-R and Ram-P dyads.


Rules for a Motion-Path FB

The sketch-path can be:

a single sketch-element

an open or closed sketch-path

crossed (8) or not-crossed (0)

Add Motion-Path FB

Toolbar :

Kinematics FB toolbar

Add Motion-Path FB

Motion-Path FB

Menu :

Add menu > Add Motion-Path FB

Add :

STEP 1: Add the Motion-Path FB to a sketch-path and graphic-area

1.Click Add menu (toolbar) > Add Motion-Path FB

The Command-Manager has one selection-box.

2.Click a sketch-element from the sketch-path

3.Click OK-tiny-13-17 in the Command-Manager

The Motion-Path FB is now in the graphic-area

A Motion-Point is at the start-Point of the sketch-element you select in the sketch-path.

Open :

STEP 2: Open the Motion-Path dialog-box

1.Double-click a Motion-Path FB in the graphic-area

- or -

2.See How to Open a Dialog-Box

The Motion-Path FB dialog-box is now open.

Notes :

You can use a Motion-Point as a Point for a Pin-Joint.

Compare : Motion-Path FB and Motion-Dimension FB

A Motion-Path FB / Motion-Point can be compared with a Motion-Dimension FB / Motion-Part.
