Offset surfaces, scale up, trim and create new BREP

Hello,

I have a referenced box with 6 surfaces. I want to offset 4 surfaces with the same fixed distance and offset the other 2 with varying distances.  

Once I have the offset surfaces, I want their bounds to define a new (larger) box.  

In the files attached, I show the work I've done so far.  I have offset the surfaces, scaled them up and am now trying to trim them to define the bounds of the new box.

Is the logic here sound?  I think there is likely a smoother way to do this, I'd appreciate some help! 

Thanks,

Daniel

Tom,

Thanks for the reply.  Indeed ScaleNU was essentially what I was looking for.  I wanted to set the z axis to scale a bit differently, so needed to Deconstruct BREP, then EvalSurf to make that happen.  See attached.  I think this is as clean as it can get...

I will download and try out your plugin, for when I run into similar problems with non planar surfaces.  

Thanks so much for your help!

Dan
