To Create a Fill Pattern in Creo Flexible Modeling

1. Click Flexible Modeling >

Flexible Pattern. The Pattern tab opens.

2. To set the pattern type, select Fill 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 area to fill with the pattern, on the References tab, click the Sketch collector, and perform one of these actions:

◦ To create a new sketch, click Define and sketch the outside boundary of the pattern. Click

. A preview of the pattern appears.

6. To select a grid template, click the arrow next to

and select a template.

7. To set the spacing between the centers of the pattern members, type or select a value in the box next to

. Alternatively, in the graphics window, drag the handle or double-click the value next to the Space label and type a value.

8. To set the minimum distance between the centers of the pattern members and the sketch boundary, type or select a value in the box next to

. A negative value makes the center lie outside the sketch.

9. To set the angle of rotation of the grid about the origin, type or select a value in the box next to

. Alternatively, in the graphics window, drag the handle or double-click the value associated with the handle and type a value.

10. To change the radial spacing for

circular and

spiral grids, type or select a value in the box next to

. Alternatively, in the graphics window, drag the handle or double-click the value associated with the handle and type a new value.

11. Optionally, set one or more of the parameters on the Options tab.

◦ Use alternate origin—Uses an alternative origin different than the default geometric center of the lead feature or geometry to place the pattern leader. Click the collector and select a datum point, coordinate system, curve end, or vertex.

◦ Follow leader location—Offsets all the pattern members from the sketch plane using the same distance as the offset of the pattern leader.

◦ Follow surface shape—Positions pattern members to follow the shape of the selected surface. Click the collector and select a surface.

▪ Follow surface direction—Orients the pattern members to follow the surface direction.

◦ Follow template rotation—For

circular and

spiral grids, orients pattern members in relation to an origin.

12. To exclude or include specific pattern members, perform these actions:

◦ To exclude a pattern member, click its black dot

in the graphics window. The black dot changes to white to show that the pattern member is excluded.

◦ To include a pattern member that has been excluded, click its white dot

. The white dot changes to black.

13. 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.
