To Create a Fill Pattern
1. Select the feature that you want to pattern and click Model > Pattern. The Pattern tab opens.
2. Select Fill from the list of pattern types. The Fill pattern options open.
3. Select an existing sketched curve, or click References > Define and sketch the area to be filled by the pattern.
 
* In Sketcher, a read-only construction point is placed at the pattern leader origin, with horizontal and vertical construction lines passing through the point.
Click OK to complete the sketch. When you select a curve or quit Sketcher, a preview of the pattern grid is displayed, based on the default values. Each pattern member is identified by .
4. Select a grid template.
 
* Click the arrow next to the button to access the grid templates.
5. To change the spacing between pattern member centers, type or select a value in the box adjacent to . Alternatively, in the graphics window, drag the handle or double-click the value associated with the Space label and type a new value.
6. To change the minimum distance between the pattern member centers and the sketch boundary, type or select a value in the box adjacent to . A negative value makes the center lie outside the sketch. Alternatively, in the graphics window, drag the handle or double-click the value associated with the handle and type a new value.
7. To specify the rotation angle of the grid about the origin, type or select a value in the box adjacent to . Alternatively, in the graphics window, drag the handle or double-click the value associated with the handle and type a value.
8. Set one or both of the following optional parameters for circular and spiral grids:
To change the radial spacing, type or select a value in the box adjacent to . Alternatively, in the graphics window, drag the handle or double-click the value associated with the handle and type a new value.
To rotate pattern members about an origin, select the Follow template rotation check box on the Options tab.
9. Set one or more of the optional parameters on the Options tab:
Regeneration option—Reduces regeneration time by selecting a more restrictive regeneration option, depending on the complexity of the pattern:
Identical—All the pattern members are identical in size, are placed on the same surface, and do not intersect each other or part boundaries.
Variable—The pattern members can vary in size, or be placed on different surfaces, but they cannot intersect each other or part boundaries.
General—There are no pattern member restrictions.
Use alternate origin—Uses an origin different than the default geometric center of the lead feature or geometry to place the pattern leader.
Follow leader location—Offsets all pattern members from the sketch plane using the same distance as the pattern leader's offset. 
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.
10. To exclude a pattern member at a certain location, click the corresponding black dot that identifies the pattern member in the graphics window. The black dot changes to white () to show that the pattern member has been excluded. You can click the white dot again while redefining the pattern to re-include the pattern member.
