I’m making kitchen utensils and I guess I need someone to explain to me like I’m a child how to cut out the “spoon” part off the model. My stock is .40 inches thick. I told CC Pro that my “base” is .30 inches and then I told it I wanted to “cut out” .18 inches at a 22 degree angle which in my mind would leave .12 inches of stock at the bottom of the scooped out portion. That is not what is happening. Am I missing a step or is my thinking wrong? Any help would be greatly appreciated!
Usually this is caused by a mismatch between job setup:
and how origin is set relative to the stock:

I find that opening the .c2d file up and drawing a box which matches the specified dimensions (draw up the cut in profile if need be) or moving the machine to the origin and then using a tape measure to measure out the dimension(s) in question will make clear where things aren’t lining up.

It’s the 3D part that gives me trouble. When I create a “base” as part of the model should it be the same thickness as my stock piece? When I tell it to subtract an amount of material does the software think I’m cutting that amount from the top of the stock or is it going to leave that amount of stock at the bottom of the cut? How does actual stock thickness relate to these parameters that I enter? I’ve watched a bunch of videos on the CC Pro software but these basic questions are never covered when it comes to the modeling portion of the software.
Whether or not the Stock is fully modeled depends on the nature of the design and how it is being approached:
- Design is being incised into the material? Model to full thickness
- Design is being placed on a surface? Model to a partial thickness to match
- Design only is being modeled? Do not model the stock, model only the part
The modeler doesn’t care about the stock thickness in the job setup. It will display any part of the model that exceeds the stock in a redish color to let you know your model is taller than the stock, but that is all.
The modeler starts building at Z zero, and all subsequent components are built relative to Z zero (when using min, max, equal), or relative to the current model (when using add or subtract).
Base stock is applied to the current component being built, before applying the merge type.
So, to model what you are describing, I first draw it up in profile to see it
Select the outside rectangle & add a flat component 0.400 height.
Select the oval, subtract a round component, 22° angle, 0.180 height, 0.100 base height.
So if I’m reading this correctly I’m telling the software to take out .180 of material at a 22 degree angle but leave .100 worth of material at the bottom (from Z zero up)…is that correct? I hope so because this explanation makes the most sense yet! If that is not enough material left to my liking would I just change the model height or the base height??
The way you described it, the vertical walls (base height of the component) are 0.100, the bowl of the spoon is 0.180, leaving a thickness of 0.120 at the bottom.
Your 22°, 0.180 height component looks like this… (0.100 grids)
Add the base height…
Now subtract that from a 0.400 block…
Now that I think of it, it’s probably best on the round component to scale the height to 0.180, as it will have a variable size if it’s an oval. This will force the total thickness to 0.180.

I actually ended up using the “scale height” feature and it worked well. I’ve been playing around with the set up on a bunch of spoons and I want to get past the point of just guessing at what I’m doing and actually understanding what I’m doing and how these inputs are affecting my end product.
It took me a bit to wrap my head around how the round component works as well.
If you don’t specify a limit (scale or limit), leaving it at ‘none’, it ignores the height value & tries to create a ‘round’ i.e. circular/arc at the angle you specify, so the height is based on the cross section distance between the vectors. Scale works just like scaling a circle in the cross section, shrinking it down or stretching it up to match the height you specify, resulting in an elliptical cross section. So to get an exact depth in the center of the spoon, estimate the angle, and limit (scale) the height to your desired depth.
