# Multiple layers of text with a graphic

as requested on support…

names carved at different levels with the swoosh being a pocket.

The first consideration is what is on each layer and to what depths each will be cut. Extant toolpaths indicate:

Top – 0.2 == Surround and Circuit Breaker Sales
0.2 – 0.239 == + Service Shop
0.239 – 0.26 == + CBS
0.26–0.28 == + Swoosh

Apparently the original (selected, so orange) was stretched to fill the space:

We clean up by removing the offset geometry (it will be replaced):

A concern here is that the text was apparently traced and this has revealed oddities in the tracing, so we reset with something reasonable:

A further concern is the depths and the tooling which will be used, so we draw this up in profile:

which immediately becomes a concern — the very thin depth differences will be quite hard to see — it is better for distinct elements to have evenly layered height differences, and it is better for shadow lines to have a greater depth which will make them easier to discern.

The tool profile drawn is a #302 60 degree V endmill, so we should be able to make up to that height of cut for a given layer, so at least we aren’t limited in tooling.

4 distinct layers are needed, and we need to not cut all the way through, so we instead divide the stock thickness by 6:

which fortuitously is a nice even 1/8"

adding three more layers we arrive at:

which leaves a double layer, 1/3rd of the material to function as a base, so it should be stable.

Next, we determine how much each layer will need to be inset by. Select the tool and a layer when both are aligned:

and do Boolean Intersection:

to arrive at 0.072" (the intersection of the radius of the tool and one layer thickness)

Next, each layer has to be offset.

Select each layer:

Assign the toolpath:

and verify the preview:

Then Boolean Offset by 0.072":

If need be, group the vectors.

Add the next layer to the selection:

and add a new Advanced V carving toolpath which starts at the bottom of the previous one:

Offset again:

add the next item to the selection:

and assign another toolpath:

The final geometry/selection is a bit odd since we want to increase the depth of the Swoosh only.

Select the text only and offset it by the 0.072" distance, this time to the outside:

Add the Swooshes to the selection:

and use Trim Vectors to remove what is not needed and isolate down to the outline of what must be cut away (the Swooshes):

Until one arrives at:

OK

OK

Join Vectors:

Yes

Deselect what is wanted:

and delete the balance:

Note that we missed a section:

So we use Trim Vectors again:

OK

OK

Join Vectors

Yes

But a mistake was made with the “U”:

Repeat the offset:

Deselect the U

Delete everything else:

and fix the offset geometry to cut consistently:

OK

We want to cut the offset U out of the swoosh, so the easiest way to do this is to ensure that they overlap by Node Editing the swoosh:

Done

Then Boolean Subtract or use Trim Vectors:

Select the two swooshes (and the offset around the unconnected “C”):

and create a toolpath:

Thank you Will,

I changed the order of height for the text a bit. Came out great.

Thank you again

Great tutorial. Would like to see this in a video tutorial.

Sorry, that’s not in my wheelhouse — you’d have to get @KevBarn14 or @wmoy to do a video.
