The ability to do this came in as a feature request — basically rather than incising the design as V carving does, carving them proud of the surface:
While one can do this in Carbide Create Pro:
it takes a while to cut them out w/ any degree of verisimilitude using a ball-nosed endmill.
Hang on for how to do it manually.
First consideration is which V endmill will be used, and how proud the letterforms will stand of the stock — we’ll use a 60 degree and 1/4" height:
Draw the centerline for the letter:
to the inside and outside by half the width dimension or so:
Add geometry around the letter:
Select the outer geometry and the centerline and do an Advanced V carving w/ pocket clearing:
Repeat for the inside:
To arrive at:
Draw up geometry which is slightly wider than the width noted above:
so as to make the desired letter:
Once one has arrived at the desired outline:
Inset by a bit less than half the desired width:
Where necessary, offset any inner features to the outside, or if need be, re-draw them:
Select the new centerline geometry and the outer and do an Advanced V carving:
Appreciate the effort here. Prismatic Lettering is a must for me, and although your tutorial works, it’s unfortunate this style of lettering/shaping requires soooo many steps. Carbide: Can you fix this PLEASE
I really don’t want to go to V-CarvePro software.
I usually have a full bed of lettering all needing this and it’s super difficult to achieve with a nested grouping of more than 20 letters.
Any other thoughts? Thanks again 
But once you do, you’ll wish you had done it sooner.
Have you tried the Pro version of Carbide Create via trial license?
The CC Pro modeling features would seem to make prismatic letters simple & straight forward to achieve.
How would it be done in the CC Pro version? I’ve been trying to figure it out but not quite getting there. Right now CC is hemorrhaging trying to calculate the toolpath.
I believe you’d need to draw up the central channel and then subtract it at an angle.
I actually have a project for a friend which want something similar (it’s making letters for casting in concrete) — but I’ll probably do it w/ OpenSCAD and drawn/imported geometry.
