Pattern of Offsets

Hi All,
Does any one know if it is possible to pattern offsets in SWX2005?
I am trying to create a parametric model with equally spaced concentric
rectangles and would like to be able to control the number of layers
but as far as i can tell the offsets need to be made individually.
There is a scale pattern in sketches but it is not usefull because I
need constant offsets.
Also I don't think the vary sketch option will work with a pattern
feature because the centroid of the sketch is not being patterned in
any direction. I could be wrong though.
Has anybody worked through this?
Cheers,
Shane

 

You mean a series of rectangles nested inside each other? Are they then
extruded? You could modify the box subroutine in the STAR benchmark to
do this.

 

Yeah, I'm trying to approximate a winding with a series of concentric
shapes.
The shape is close to a rectangle, but has chamfered corners with
fillets at the ends of the chamfers. So an expanding pattern using
this repeated shape with a constant gap between them. The fillets are
getting larger as the shape offsets though so the form of the shape is
changing.
What's the STAR benchmark?
I have found a way that almost gets there by extruding the whole shape
and using sketch patterns to sweep cuts internal to the lump.
Unfortunately when the sketch is selected, after closing it, only the
pattern distance is exposed not the pattern number. If that makes any
sense???
