I am starting with the engraving on the metal box.

So remove all staff from the box.

add a metal box with an open plane setting.

and add designs

Then settings

auto measure

framing

and start engrave.

My second part is glasses.

This one needs to take time to stable and flat.

let's stay the red dot on the glasses frame.

Add text and choose output and ignore to all other images.

Then add the setting to text.

auto measure

framing

and start engraving

The last one is the glasses case.

select the images for the glasses case and choose the output option and all others to ignore.

Auto-measure

framing

and start engraving.

All done.

Thank you
