Custom shape scale behavior

[rickscr]

I'm trying to create a custom master shape for a building.  I want to be able to re-size it, but have the angle of the roof stay the same.  Anyone know how to do this?

two options

1)  Simple, lock perspective and scale via corners
2)  Complex, in the shape geometry, factor in the angle
     Something like
              Geometry1.X3 = Geometry1.X2+ 1/2*width*cos(angle)
              Geometry1.Y3 = Geometry1.Y2+ 1/2*width*sin(angle)
              Geometry1.X4 = Geometry1.X3+ 1/2*width*cos(angle)
              Geometry1.Y4 = Geometry1.Y3 - 1/2*width*sin(angle)
     Probably have to play with the formulas...but I think you get the idea (take previous point and add 1/2 width and factor in angle)
     If you want to protect these cells from any user action, use guard() on the formula

Option 2 it is, since I need the shape to scale in both directions.  I'm beginning to see why the shapesheet is so important....

Thanks for your help!
