About Dimension Patterns
You can create a dimension-driven pattern to specify multiple occurrences of a component in an assembly. The dimension-driven pattern uses assembly constraint dimensions such as Distance or Angle Offset offset values. The rules for creating a dimension-driven pattern are the same as those for feature patterning in Part mode.
 
* If you must redefine a dimension pattern, redefine the component placement first, and then redefine the pattern.
