As requested on support…
You helped me with my 3D plaque of the USA 250th, sizing it to 14 X 14.
I would like one a little smaller, like 11/25 X 11.25.
Where the file is:
First, File | Export the 3D model as a PNG:
Make a new/blank file:
and adjust the Job Setup per:
Ok
Draw a rectangle to match the XY stock dimensions:
and import the pixel image as a Texture:
adjusting the settings and the 3D model until one arrives at what is wanted:
right-click on the 3D model to get the outline:
OK
and use that vector for the 3D toolpaths.
