| STEP 6: ||Edit the new Part|
| STEP 7: ||Add an two Arcs and two Lines to give the Path of the Belt|
| STEP 8: ||Add a Line, drag from the Centre of the Arc near the Part Axes|
| STEP 9: ||Add a dimension to each Arc|
Step 9 is complete
Note that the centre of the Arc is not at the Origin of the Part.
A Drive Pulley has one important rule -
'You must merge the centre-Point of the Arc and the start-Point of the Line'
However, a rule that you might not know is:
'You cannot merge the centre-Point of the Arc with the start-Point of the CAD-Line along the centre of the Part'.
This means you cannot use the CAD-Line for the centre-Point of the Arc.
This is why we added a new Line to merge the centre-Point of the Arc with it. This is the only reason.
