To Create a Curve Pattern in Creo Flexible Modeling
1. Click Flexible Modeling > Flexible Pattern. The Pattern tab opens.
2. To set the pattern type, select 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, on the References tab, click the Sketch collector, and perform one of the following actions. The sketch must contain a curve.
To select an external sketch, select the sketch.
To define an internal sketch, 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 Sketch > Setup > Feature Tools > Start Point.
7. To define the distance between pattern members along the sketch, next to , type a value.
8. To define the number of pattern members, next to , type a value.
9. 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.
10. To set the attachment options, click the Attachment tab and do the following:
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.
