  Is there an elegant way to build a round window with the [Radial Cockpit Window](https://www.bricklink.com/v2/catalog/catalogitem.page?P=4740pb005#T=P)? I've tried experimenting with vertical clip plates but it just ends up looking odd.

  I'm gonna suggest a SNOT contraption relying on two [3659 Arch 1x4](https://www.bricklink.com/v2/catalog/catalogitem.page?P=3659), two 1x1 round plates in trans clear, and one [2654 2x2 round plate with rounded bottom](https://www.bricklink.com/v2/catalog/catalogitem.page?P=2654#T=C&C=12), also in trans-clear:

  The 2x2 plus 1x1 round plates should just fit within the arches of the arch bricks and provide just enough friction to hold:

  There *should* be enough room inside the 1x4 arch brick to snugly accommodate the 2x2 plate:

  It's also possible to use the (relatively new) part [78666 Arch 1x2 Inverted](https://www.bricklink.com/catalogItemIn.asp?P=78666) together with [3659Arch 1x4](https://www.bricklink.com/v2/catalog/catalogitem.page?P=3659) to achieve a SNOT-less window frame, for example:
  
  [![CAD diagram of window assembly](https://i.sstatic.net/gDoX3.png)](https://i.sstatic.net/gDoX3.png)
  
  Bear in mind that the curve of the inverted 1x2 arches is not the same as the 1x4 arch, and there'll be a small (about 1/10th of a stud) gap between the inverted arches and the 2x2 dish:
