Creating a 3D terrain carving from an STL

[WillAdams (William Adams (Carbide 3D))]

…as requested on support…

Given an STL:

we import it into Carbide Create…

[WillAdams (William Adams (Carbide 3D))]

which is rather shallow compared to the original 3D model:

If we instead model the design at the original size/proportion:

(and also set the Model Resolution to Very High)

which gives the size in comparison to the original of:

and if we import into this we get:

which if we apply 3D toolpaths we get:

Next, we look at scaling the design up…

[WillAdams (William Adams (Carbide 3D))]

48 inches is 1219.2mm, which if we divide in the long dimension, 108.42mm we get a scaling factor of: 11.2451577

Multiplying that by the height of 9.89 we get: 111.21461mm — converting that to Imperial for familiarity we get: 4.37852795 inches.

Rounding that off to 4.375 inches, we set up the file for these dimensions:

so we draw in geometry and import:

which we can then apply 3D toolpaths to:

which then previews as:

If we then export this as a PNG:

We can then reimport with a more modest height, but still preserve much of that height difference:

insofar as 1" of thickness allows:

which when cut w/ the 3D toolpaths previews as:
