This New Component situation is royally messed up.
The key to the problem is that the current default system does not cover an important use case, and the documentation is wildly incorrect and misdirecting.
Use case:
- New Design type = Hybrid (so that it can contain subsidiary components) <-- there is a default setting for this.
- AND within that project, new components default to type Part, and Internal. There is no setting to make this the default. Instead, the New Component dialog defaults to Hybrid, apparently following the setting for New Design? If you manually change that to Part, the dialog currently defaults to Internal (favorable for my use case). And oddly, those new Part type components can contain subsidiary components (unlike a Design of type Part).
So the immediately missing piece is some way to set New Component to default to Part -- Internal. (or External if you prefer that.)
But greatly undermining anyone's ability to understand this is the complete bollocks from Assistant (and presumably in turn from Help). In the following discussion with Assistant, my questions and comments are in blue and the text marked in red is incorrect info from Assistant, and directly blows up a user's ability to understand this system.
ME: Can a Part design have subsidiary components?
Assistant: Yes, but with an important limitation. Here's what the documentation says:
Part Design & Components
A Part design can only contain one component — the root/default component itself. Specifically:
You cannot create sub-components (internal child components) within a Part design.
You cannot insert external component files into a Part design — commands like Place or Insert Component are unavailable/greyed out.
The "Create Components from Bodies" right-click option is also missing in a Part design.
[...]
So in short: if your workflow requires subsidiary components, Hybrid is the most flexible choice — keeping in mind the trade-off we discussed earlier (all components within a Hybrid will be external).
(So the initial "Yes" is contradicted by the rest of the statement)
ME: How do I set defaults so that a new design is Hybrid, and new components within such a design are Internal?
Assistant:
Based on everything retrieved in our conversation, I need to give you a straightforward answer here:
That combination is not possible. The two goals are mutually exclusive in Fusion:
| Goal |
Required Design Type |
| New design defaults to Hybrid |
Hybrid — set in Preferences > General > Default Design Type |
| New components default to Internal |
Only works in Part design — not available in Hybrid |
(but how do new components default to Internal if new components are supposedly not allowed in a Part design???)
As established earlier, any component created in a Hybrid design is always External — there is no setting that overrides this, because it's a fundamental characteristic of the Hybrid design type, not a preference.
Your Realistic Options
- If you want Internal components ? Set your default design type to Part. Accept that you cannot insert external component files. (but Part designs don't allow subsidiary components)
- If you want Hybrid ? Accept that all components will be External, and plan your workflow around that (e.g., using Edit In Place to work on them in context).
- If you need both modelling AND internal components ? Consider whether your use case actually needs a Hybrid at all. A Part design with multiple bodies may achieve what you need without requiring components at all.
Would you like help thinking through which design type best fits your workflow?
ME: Then how do you explain that I just created a Hybrid design, then added a component, and in the new component dialog I can set the type to Part and Internal?
Assistant:
You are absolutely correct, and I apologise for the misinformation in my earlier responses. The official documentation confirms exactly what you observed:
The Correct Behaviour
In a Hybrid design, the New Component dialog gives you:
- Type = Part + External unchecked ? creates an Internal component inside the active design ?
- Type = Part + External checked ? creates an External component (saved as a separate file)
- Type = Assembly, Hybrid, Sheet Metal, or Linked PCB ? always creates an External component
So internal components are possible in a Hybrid design — you just need to set Type to Part and leave External unchecked.
To Answer Your Original Question
To default new components to Internal in a Hybrid design, when creating a new component simply ensure:
- Type is set to Part
- External is unchecked
The "External" checkbox is only available when Type is set to Part in a Hybrid design — and unchecking it is what makes the component internal.
I was relying on an outdated support article that did not reflect current Fusion behaviour. Thank you for correcting me.
ME: You now understand the behavior I want. But you didn't answer how to set this as the default: New design = Hybrid, and I want New component within such design to default to Part and Internal, without hvaving to fool around with its individual settings.
Assistant: Good point — let me search specifically for whether a default can be set for the New Component dialog settings.
There is a partial answer in the documentation, but not a complete one. Here's what it says:
"The new component type in this dialog defaults to the default design type defined in the Preferences."
This means:
- Default design type = Hybrid ? set in Preferences > General > Default Design Type [YES]
- Default component Type = Part ? set in Preferences > General > Default Design Type to Part, which then drives the Type field in the New Component dialog [YES]
- Default External = unchecked ? the documentation does not describe any preference or setting that controls the default state of the External checkbox
So the short answer is: there is no documented way to pre-set the External checkbox to unchecked by default. You can control the default design type (which influences the Type dropdown in the dialog), but the External checkbox does not appear to have its own default preference.
Given that your preferences are currently set to default to Part (which is why the component Type shows Part in the dialog), the External checkbox defaulting to checked is the gap — and based on the available documentation, there is no setting to change that default behaviour. (<--- Assistant misunderstood my settings, but no matter. )
This may be worth submitting as a feature request to Autodesk if it's a recurring friction point in your workflow.
