Scenario

Complete a toothed V-belt using a curve pattern.

Task 1. Create a curve pattern of the tooth_section sketch.

1. Select the tooth_section curve from the model tree.

Right-click and select Pattern.

Edit the pattern type from Dimension to Curve.

Notice that the Use Member Spacing option is selected.

Type 16for the spacing value and press ENTER.

The two pattern members above the blue arrow are not spaced equally with the other members. With the Use Member Spacing option, the system places a

ember on the start point of the curve, and then places members along the curve in the direction of the arrow at the specified spacing value.

2. Type 25for the spacing value and press ENTER.

Click Complete Feature .

Notice that the instances are evenly spaced because the curve length (425) is evenly divisible by thespacing value (25).
