STEP 1 : Add the Belt-Path:
Edit a Part, and sketch a sketch-loop with Lines and Arcs. The sketch-loop will become the path of the Belt.
Make sure you add a dimension to each Arc. Also, it is best to make the sketch fully constrained [the sketch should be black]
STEP 2 : Add a Motion-Point to the Belt-Path.
Use 'Add and select the sketch-loop. This adds a Motion-Point to the 'Belt'.
The Motion-Point indicates the motion of the Belt.
STEP 3: Add a Part that will become the Pulley
Add a rotating-Part : its Pin-Joint at the centre-Point of an Arc in the sketch-loop. The rotating-Part becomes a Pulley.
The rotating-Part may be:
or
STEP 4: Do :
Use [see the Command-Manager to select the correct elements].
| • | If the rotating-Part [Step 3] is a : |
| o | the Motion-Point [on the Belt] becomes driven by the motion of the rotating-Part. |
| o | The rotating-Part becomes a DriveR Pulley. |
| o | The default colour of a DriveR Pulley is Cyan. |
| o | There is a maximum of ONE DriveR Pulley in one belt/sketch-loop. |
- or -
| • | If the rotating-Part [STEP 3] is not a kinematically-defined Part: |
| o | the rotating-Part becomes driven by the motion of the Motion-Point on the Belt. |
| o | The rotating-Part becomes a DriveN Pulley. |
| o | The default colour of a DriveN Pulley is Magenta. |
| o | There is no limit to the number of DriveN Pulleys in one sketch-loop. |
