Scenario: CNC Pattern Printing on Objects I walk up to the pattern printer kiosk. I select a pattern I want, fluted, just like those Ionic found in Greece with the grooves up and down the column. Then I place my object, a thick dowel 1 meter in length, into the CNC printer. Then I select ESTIMATE and the CNC printer scans my object, then the kiosk tells me it will cost $20. I select ORDER and the kiosk's CNC printer cuts at my dowel producing a grooved pattern on it. After cutting my dowel, I take it and the kiosk prints an invoice for me. I will give this invoice to a cashier and will pay the cost to the cashier.

This is a software design question, follow the descriptions and draw two sequence digram.
