Linear Pattern while maintaining geometric constraints

Hi all,


I'd like to create a pattern that maintains geometric constraints.  If you look at the sketch above, you can see that if you vary the 3.000 dimenstion, you'll have all dimensions remain the same, with the sketch rotating about Axis 1, since the geometry is constrained such that the centerline passed through Axis one.  Change the 3.000 dimension to 1.000 and you get below:

The angle of the sketch changes, but all of the dim's remain constant because they are defined and the centerline stays running through Axis 1.


If I now go to pattern this and use the 3.000 dimension as the direction, SW doesn't maintain the fact that I had geometric constraints and I get the same shape at whatever increment I use on the pattern without the shape maintaining the focus to the axis, as it is in the sketch.


Therefore, is there a way to maintain the geometrical relationships defined in the sketch while patterning?  ProE will maintain geometrical relationships, but I am trying to model a particular part in SW instead.


Please let me know if I need to clarify this more.
