Ok, I wanted a solution that would work this weekend, so I grabbed the OpenCutList source code and tweaked a single line that, together with some changes in my model, gives me a solution.

I made a 2 minute video explaining why I need this solution and how I went about creating it: https://youtu.be/MlnRIQxDo4Y

Quick summary: I have a dynamic component for a cabinet side panel. It is set up to create a toe kick of a configurable size regardless of you resize it. Making this work requires that the panel be made up of three nested objects, and the component resizes these objects to account for the toe kick. OpenCutList was creating a separate part for each of the three nested object, but what I need is to create a single part that is the union of the three sub-parts. My solution was to create a single  hidden part of the right size, and to resize it so that it's always the correct size for the actual part I need.

The next step is to tweak OpenCutList to use my hidden part and ignore the visible but unwanted "sub-parts" that make up the component. I did that by changing a single line in the OpenCutList extension to always use parts (even if hidden) that are tagged as "OpenCutList: IsPart" and to ignore parts that are tagged as "OpenCutList: IsNotPart"

```
if (entity.visible? && _layer_visible?(entity.layer, path.empty?) && entity.layer.name != "OpenCutList: IsNotPart" || entity.layer.name == "OpenCutList: IsPart") 
```

I acknowledge this is an incomplete hack, but I do see value in having a more general version of this capability where OpenCutList defines a part for an entire component rather than all of the sub--components. This would really help anyone who needs to machine parts down from their initial cuts (e.g. my situtation with multiple adjacent parts, a turned part, etc.)

Maybe 2 easier "tweaks" are :

1. Convert sub-component into groups. (OCL ignore groups) - the standard solution that is not a tweak 😛
 
2. Or set the cut opening attribute to true to your sub components. (OCL ignore cut opening components) - the tweak solution that works without modifying OpenCutList sources.

Thx Boris! Did not know about the grouping behavior, and that solves half the problem, which is making OCL ignore the sub-components.

Do you know how to make OCL create a part for the full component?

Hi Jeff,

In the above screenshot you can see that 2 sub-components create only 1 part in OCL.

OK! This works, Boris, though I found that OCL chokes if a component contains a single group.

Is the behavior you've shared with me documented?

Really, how did you obtain this ?

If I try it works :

Do you talk about using the "cut opening" attribute ?

No, it's more a tweak than a real feature :)
