Can this be made into sheetmetal

My client gave me a PDF file. From which was able to replicate the design in SW. However, I need to flatten this pattern so the fabricator can correctly place mounting holes prior to forming it.

The material will be 1/4" thick acrylic heat formed. A piece of .04 aluminum will be glued to the surface after forming. The aluminum is the piece we need to flatten.

Any ideas?
thanks in advance

Yeah, you can do it, but it might get ugly. You have to start by deleting all your features, but you can keep the sketches. In the first sketch all you need is 1 spline. Then offset a plane and copy the first sketch to the copied plane, then use the two sketches to make a lofted bend. Then the part is sheet metal. You can then use the sketch to blank out thepart you want to keep, but SW09 is gonna give you some difficulties about multibodies in a sheet metal part, so you may need to do this all again for the second part, or use configurations or some other trick.

  Thanks Matt
  
  Great tip. It worked well, however, now I can't seem to flatten it. Can you help just a little more and see if you can flatten it? Thickness doesn't matter, I can adjust that stuff once I get the pattern to flatten/unflatten.

    Ok, I can see you're using an older version of the software. You offset the sketch by the thickness of the sheet metal, but as you see that doesn't work.
    
    Sketch squiggly spline on Front plane
    offset Front plane by X inches
    use Convert Entities to copy squiggly spline to new plane
    loft between 2 sketches
    flatten

Carter ... the Lofted Bend you created was for the ~1/4" thickness. It should have been across the 8" width.

  thanks to both Matt and Kelvin
  
  K's answer worked the best. Now, flat and develop length dead on.
  
  Sorry about the delay on updating, had a 'hot' job.
