To Create a Curve Pattern in Creo Flexible Modeling
1. Click > 
Flexible Pattern. The Pattern tab opens.
Flexible Pattern. The Pattern tab opens.2. Under Type, select 
Curve from the list.
Curve from the list.3. To select references to define the pattern leader, click the References tab, and perform any of the following actions:
◦ Click the Leader surfaces collector, and select surfaces. If needed, click Details to open the Surface Sets dialog box.
◦ Click the Leader curves and datums collector, and select curves and datums.
4. To pattern the selected rounds and chamfers that attach the patterned geometry to the model, click the References tab and check the Transform selected attachment rounds/chamfers check box. If you do not check this check box, the selected attaching rounds and chamfers are removed and optionally recreated.
5. To define the sketch to place pattern members, perform one of the following actions. The sketch must contain a curve.
◦ To select an external sketch, on the Pattern tab, click the 
Sketch collector, and select a sketch.
Sketch collector, and select a sketch.◦ To define an internal sketch, on the References tab, click Define and create a sketch.
 | In Sketcher, a read-only construction point is placed at the pattern leader origin, with horizontal and vertical construction lines passing through the point. |
6. To change the start point and direction of the curve, perform these actions:
a. On the References tab, click Edit. The Sketch tab opens.
b. To select a different start point for the sketch, select a curve end in an open sketch, or select any vertex for a closed curve.
c. Click > > > .
7. To define the spacing and number of pattern members, perform one of the following actions:
◦ To define the distance between pattern members along the sketch, click 
Spacing, and type a value.
Spacing, and type a value.◦ To define the number of pattern members along the sketch, click 
Number of Members, and type a value.
Number of Members, and type a value.8. If needed, click the Options tab and set options:
◦ Use alternate origin—Use an origin different than the default geometric center of the lead feature or geometry to place the pattern leader.
◦ To attach all pattern members to the model geometry, select the Attach pattern members check box.
| | When the Attach pattern members check box is not selected, the resulting geometry is a quilt. The appearance of the original solid surfaces is propagated to both sides of the resulting quilt. |
◦ To attach all pattern members to the model geometry with rounds or chamfers of the same type and dimensions as the pattern leader, select the Create rounds/chamfers check box.
