Inverted Rounded Corner Rectangles (Incut Rectangles)

[MEB]

Thank you for the info Frank. Already working to get it...

Big Frank, this is a great technique and it also works with regular rounded boxes, after you convert the box to editable shapes.

It even works in Web Designer too (very useful when using rounded text panels etc.), but you have to first convert the box by selecting Arrange/Combine Shapes/Add Shapes.

I know it is not so accurate but why did no one state the obvious. After doing the Ctrl+Shift+S and if you have your constraint angle set at 45 then Ctrl+drag the nodes around saves a lot of time.

...because

1. In the solution I gave to the OP there was no need for Ctrl+Shift+S
2. I did specifically mention Ctrl+Drag

Just read up a few posts until you see my diagram.
