To Create a Point Pattern using a Pattern of Points in Creo Flexible Modeling
Use a pattern of points as a reference to place instances of a feature pattern.
1. Create a pattern feature that contains datum points.
2. Select the surfaces to be patterned, and click > 
Flexible Pattern. The Pattern tab opens.
Flexible Pattern. The Pattern tab opens.
3. Under Type, select 
Point. The Point pattern options appear.
Point. The Point pattern options appear.4. To use points in a pattern feature made of datum points to create the pattern, click 
From Pattern.
From Pattern.5. To define pattern member placement, make sure the Reference collector is active, and select the pattern header of a pattern feature that is made of datum points.
6. The orientation of all the non-lead members of the pattern is same as the lead member when a Pattern of Points is selected as a reference.
Optionally, to align the pattern members with the leader by using an origin different from the default origin, click the Use alternate origin collector, and then select a datum point, coordinate system, curve end, or vertex. The default origin is located at the center of an imaginary bounding box around the pattern leader geometry.
◦ 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.
