-Next, I lay everything flat on the XY plane and did a make 2D. For nesting I used an online service called [nestandcut.com](https://nestandcut.com/) to nest all parts in twice the quantity on a sheet of 1220x1220x15 mm. (Half a sheet). I uploaded a dxf file that I export from Rhino and imported the nested dxf back.

-1.  The cutting height did not match the level of the stock. It was cutting in the air. I adjusted this by going bacto the material panel and changing the stock thickness to 15mm. (It was 300 by mistake)
