Question 1

Before inspecting Component A, a designer manually hides Component C while Components A and B remain visible. The designer then isolates Component A, completes the inspection, and chooses Unisolate.

What visibility state should the designer expect after leaving isolation?

  1. Components A, B, and C are all visible because Unisolate turns on every component
  2. Only Component A remains visible because Unisolate does not restore prior visibility
  3. Components A and B are visible, while Component C returns to its previously hidden state (correct answer)
  4. Only Components B and C are visible because the isolated component is hidden afterward
Explanation: When working with Fusion 360's isolation feature, the key concept to understand is that Unisolate restores the pre-isolation visibility state — it acts like an "undo" for isolation, not a global visibility reset. Whenever you see a question about isolating components, ask yourself: what was the visibility state before isolation occurred? In this scenario, the designer manually hid Component C before isolating Component A. That manual hide is recorded as the baseline state. When Isolation is activated, Fusion 360 temporarily suppresses everything except the isolated component. When the designer then chooses Unisolate, the software reverts to that saved baseline — meaning Components A and B reappear (they were visible before isolation), and Component C remains hidden (it was already hidden before isolation). That logic confirms C is correct. A is wrong because Unisolate doesn't blindly turn on every component — it specifically restores whatever visibility configuration existed before you entered isolation. If it did what A describes, manually hiding something before isolating would be pointless. B incorrectly suggests that only the isolated component stays visible after Unisolate, which would make the feature nearly useless for any real workflow. D is doubly wrong: it claims the isolated component gets hidden afterward (it doesn't), and implies the other components become visible in a contradictory way. A helpful tip: think of Unisolate as a visibility snapshot rollback. Fusion 360 takes a snapshot of visibility the moment you isolate, and Unisolate returns you to exactly that snapshot. Any changes you made before isolating persist; nothing gets added or removed beyond that baseline.

Question 2

A model contains visible solid bodies, construction planes, sketch curves, and joint origins in the same region. The designer must window-select only sketch curves for deletion, without hiding the other object types.

Which preparation most reliably limits the window selection to the intended geometry?

  1. Enable Sketch Curves in the selection filters and disable the other relevant object types (correct answer)
  2. Enable Face Priority so the window ignores construction and assembly objects
  3. Activate the sketch so every object crossed by the window becomes sketch geometry
  4. Isolate the sketch so all solid, construction, and assembly objects are permanently removed
Explanation: When working with complex Fusion 360 models containing multiple object types, the Selection Filters panel is your precision tool for controlling exactly what a window selection can "see" and capture. Questions like this test whether you understand that filtering happens before selection, not after. The most reliable preparation is A — enabling Sketch Curves in the selection filters while disabling bodies, construction planes, and joint origins. The Selection Filters toolbar lets you toggle specific object categories on or off. When you disable all non-sketch types, your window drag physically cannot select them, regardless of what geometry it crosses. This gives you deterministic, repeatable control over mixed-content regions. B is incorrect because Face Priority affects how Fusion resolves overlapping geometry when you click a single point — it doesn't filter object types from a window selection or ignore construction and assembly objects. C is a tempting trap. Activating a sketch does confine your editing context somewhat, but it doesn't prevent a window selection from capturing joint origins or construction planes that fall within the same area. Sketch activation changes your editing mode, not your selection filter rules. D misrepresents what Isolate does. Isolate hides everything except the chosen object — it doesn't permanently remove anything — but more importantly, the question explicitly states the designer must avoid hiding the other objects. Isolation would violate that constraint entirely. Study tip: On Fusion 360 questions involving selective manipulation in dense models, always look for answers that reference Selection Filters first — they provide the most surgical control and are a favorite exam topic precisely because many users overlook them.

Question 3

During repeated design reviews, the same six nonadjacent components must be selected to inspect properties and apply commands. The components are distributed across several browser branches, and their visibility may change between reviews.

Which workflow most efficiently preserves this reusable group without restructuring the assembly?

  1. Create a selection set from the six components and recall the set during each review (correct answer)
  2. Isolate the six components once and use the isolation state as a permanent selection group
  3. Enable Component Priority and redraw a crossing window during every design review
  4. Move the six components into one new component so a single click selects every item
Explanation: When working with Fusion 360 assemblies, questions about repeatedly selecting the same components test your knowledge of selection sets — a dedicated tool designed exactly for this workflow. Ask yourself: does the solution need to be reusable, non-destructive, and independent of component visibility or browser structure? Selection sets, created via the Selection Sets panel, let you name and save a specific group of components. During each design review, you simply click the saved set to instantly reselect all six components — regardless of where they sit in the browser hierarchy or whether their visibility has changed. This makes A the correct answer: it's persistent, reusable, and requires no assembly restructuring. B is a trap because isolation is a display state, not a selection mechanism. Isolation hides everything else visually but doesn't store or recall a selection group — and it resets when you exit it. C misunderstands Component Priority mode, which changes how window selections interact with component vs. body geometry. It doesn't remember which components you want, so you'd still need to manually identify and drag-select the six targets every time — error-prone and inefficient. D is tempting but destructive: merging six nonadjacent components into one new parent component fundamentally changes the assembly's structure, breaks existing references, and is far more invasive than the question permits ("without restructuring the assembly"). As a study tip, watch for Fusion 360 questions that describe repetitive multi-component workflows — they almost always point to selection sets as the answer. If the question mentions saving time across multiple sessions without altering structure, selection sets are your tool.

Question 4

A top-level assembly contains a subassembly named Clamp. Clamp contains two child components and three bodies. The designer needs to work with the entire Clamp structure while temporarily removing all unrelated top-level components from the canvas.

Which action best produces the required working context?

  1. Activate one child component so unrelated top-level components are automatically hidden
  2. Isolate the Clamp subassembly so its contained components and bodies remain visible (correct answer)
  3. Apply Face Priority to Clamp so only its internal geometry remains displayed
  4. Hide the Clamp subassembly so its children are protected from accidental selection
Explanation: When working in Fusion 360 with complex assemblies, understanding how visibility and activation tools differ is essential. The key concept here is Isolate — a command that temporarily hides everything in the canvas except the selected component or subassembly, letting you focus on a specific structure without permanently altering visibility states. In this scenario, right-clicking the Clamp subassembly and choosing Isolate (answer B) is exactly what you need. Fusion 360's Isolate command hides all unrelated top-level components while keeping Clamp's child components and bodies fully visible and accessible. When you exit isolation mode, the original visibility state is restored automatically — making it a non-destructive, temporary working context. Answer A describes activating a child component, which shifts the editing context into that component, not the full Clamp structure. Activating a child would make the other Clamp children harder to interact with and doesn't clean up the canvas the way the question requires. Answer C references Face Priority, which is a selection filter that controls what type of geometry gets selected on click — it has nothing to do with hiding or isolating components. Answer D proposes hiding Clamp itself, which would make the very subassembly you need to work on invisible — the opposite of the goal. A useful pattern to remember: when a question mentions "temporarily removing unrelated components" while keeping a specific structure fully accessible, think Isolate. It's Fusion 360's dedicated tool for this exact workflow, and it's reversible. Don't confuse it with Activate (changes editing scope) or Hide (removes visibility of the target itself).

Question 5

An assembly contains three visible components, each with one body. Body Priority is enabled. The designer drags a selection window from right to left so that it completely encloses the first body, crosses only part of the second body, and does not touch the third body.

Which objects should be selected when the drag is completed?

  1. Only the first body, because a selection window requires complete enclosure
  2. The first and second bodies, because the crossing window touches both (correct answer)
  3. The first and second components, because assembly selections resolve to components
  4. All three bodies, because Body Priority overrides the window boundary
Explanation: When working with selection windows in Fusion 360, the key distinction is between two window types: a selection window (dragged left to right) selects only fully enclosed objects, while a crossing window (dragged right to left) selects any object that is either fully enclosed or partially touched by the window boundary. This question tests whether you know how crossing windows behave alongside Body Priority. Because the designer drags from right to left, this creates a crossing window. A crossing window captures the first body (fully enclosed) and the second body (partially intersected), making B the correct answer. The crossing window's inclusive behavior means partial contact is enough for selection — the second body qualifies even though only part of it falls within the window. Choice A is wrong because it describes the behavior of a standard left-to-right selection window, not a crossing window. Requiring complete enclosure is the wrong rule here. Choice C introduces a misconception about how Body Priority interacts with component resolution — when Body Priority is enabled, Fusion 360 targets bodies directly rather than resolving selections up to their parent components, so you get bodies, not components. Choice D misrepresents what Body Priority actually does; it controls what type of object gets prioritized during selection, not whether the window boundary is ignored. The third body is untouched and remains unselected regardless of any priority setting. A useful habit: always note the drag direction before answering selection questions. Right-to-left means crossing window (generous selection); left-to-right means standard window (strict enclosure only). Pair that with whatever priority mode is active to predict exactly what gets selected.

Question 6

While preparing an assembly operation, a designer must select two entire solid bodies without accidentally selecting their individual faces. Both bodies belong to components that contain additional bodies.

Which setting best supports the required selection while preserving access to the individual bodies?

  1. Enable Component Priority, because it selects the owning components and their full contents
  2. Enable Face Priority, because clicking any face identifies its complete solid body
  3. Enable Body Priority, because clicks resolve to bodies instead of faces or components (correct answer)
  4. Enable Edge Priority, because a body's boundary edges identify the full solid body
Explanation: When working in Fusion 360 assemblies, the Selection Priority filter controls what type of geometry gets resolved when you click in the viewport. Understanding each priority mode is essential for efficient assembly workflows. The scenario requires selecting whole solid bodies — not their faces, not their parent components. Body Priority (C) is the correct choice because it tells Fusion 360 to resolve any click directly to the body level, regardless of which face or edge you physically click on. Crucially, it still gives you access to individual bodies within multi-body components, which is exactly what the designer needs. Option A is tempting but wrong. Component Priority would select the entire component, which may contain multiple bodies you don't want selected together. The question specifically states the components contain additional bodies, so this would over-select and break the requirement for precise body-level targeting. Option B is a classic trap. Face Priority does not automatically identify a complete solid body — it resolves to the individual face you clicked. You would need extra steps (like right-clicking to select the parent body) rather than a direct click selecting the body itself. Option D is similarly flawed. Edge Priority resolves clicks to individual edges, not to the full body that edge belongs to. Edge priority is useful for sketch constraints or measurements, not for body-level selection in assemblies. A good study tip: when a Fusion 360 question asks about selection in assemblies, map the four priority modes to their resolution level — edge → face → body → component — and match the mode to the lowest complete unit the task requires.

Question 7

A hidden component lies entirely inside the rectangular area of a window selection. Several visible components also lie inside that area. The Components selection filter is enabled.

What is the expected effect of the window selection?

  1. It selects all enclosed components, including the hidden component, because the filter is enabled
  2. It selects the enclosed visible components but does not canvas-select the hidden component (correct answer)
  3. It selects only the hidden component because hidden objects receive selection priority
  4. It selects no components because one enclosed component is unavailable in the canvas
Explanation: When working with selections in Fusion 360, it's essential to understand the difference between what selection filters allow and what the canvas can actually interact with. Selection filters define which object types are eligible for selection — they don't override visibility rules. Window selections in Fusion 360 only capture objects that are currently visible and interactable in the canvas. Even if a component is entirely enclosed within the selection rectangle, if it's hidden, the canvas simply cannot "see" it to select it. The Components filter being enabled confirms that components are the target object type, but visibility is a prerequisite that operates independently of filters. So B is correct: visible components inside the window get selected; the hidden component does not. Choice A is the most tempting trap. Students assume that because the filter is enabled and the component is geometrically inside the selection area, it should be captured. But the filter governs type, not visibility — enabling it cannot resurrect a hidden object for selection. Choice C introduces a fictional rule: Fusion 360 has no concept of "hidden objects receiving selection priority." Hidden means excluded, not prioritized. Choice D overcorrects in the opposite direction — the presence of one hidden component doesn't block the entire selection. The visible components inside the window are still selected normally; the hidden one is simply skipped. A useful rule of thumb: in Fusion 360, think of visibility as a gate that comes before filters. An object must first be visible to enter the selection pipeline, and then filters determine whether its type qualifies. Keep this layered logic in mind whenever a question mixes filters with hidden objects.

Question 8

One component contains three separate bodies. A designer wants to inspect only the second body while keeping the component's assembly position unchanged and avoiding accidental selection of its two sibling bodies.

Which action is most appropriate?

  1. Activate the parent component, because activation automatically hides its unselected sibling bodies
  2. Create a selection set containing the second body, because recalling the set prevents the sibling bodies from being selected
  3. Enable Component Priority, because component selection displays only the body that was clicked
  4. Isolate the second body, because isolation limits visibility without changing assembly placement (correct answer)
Explanation: When working in Fusion 360's assembly environment, questions about visibility and selection control often hinge on understanding which tools affect geometry display versus component position or hierarchy. Keep that distinction in mind here. The scenario needs three things simultaneously: inspect one body, preserve the assembly position, and prevent accidental selection of sibling bodies. Isolating the second body (D) accomplishes all three. The Isolate command hides everything except your selected geometry in the canvas, making sibling bodies invisible and therefore unselectable — and critically, it does not move or redefine any component's position in the assembly. When you exit isolation, everything returns exactly as it was. A is wrong because activating a component does not automatically hide sibling bodies. Activation changes the editing context — it lets you modify that component's contents — but all bodies in the viewport remain visible and selectable. You'd still risk clicking a sibling body accidentally. B is wrong because a selection set is a recall shortcut, not a visibility filter. It lets you quickly re-select a predefined group of objects, but it does nothing to hide or lock out the other bodies. Sibling bodies remain fully visible and clickable. C is wrong because Component Priority is a selection filter that prioritizes components over bodies or faces when clicking — it doesn't isolate or hide anything. It changes what gets selected on a click but won't prevent you from accidentally selecting the wrong component in a crowded assembly. As a study tip: whenever a Fusion 360 question mentions "inspect without disturbing placement," think Isolate — it's purely a display operation with no positional side effects.

Question 9

A designer needs to select an internal face located directly behind an exterior face. Temporarily hiding the exterior body would disrupt the current visibility setup, and repeatedly clicking the same location continues to select the exterior face.

Which selection workflow most directly accesses the internal face without changing object visibility?

  1. Use Select Other at that location and choose the internal face from the candidate list (correct answer)
  2. Enable Component Priority and click again until the internal face becomes active
  3. Create a left-to-right window around the area and remove the exterior face afterward
  4. Isolate the exterior body and then select the internal face through its visible surface
Explanation: When you need to select geometry that's hidden behind other faces without touching visibility settings, Fusion 360's Select Other tool is the key concept being tested here. This tool lets you cycle through all selectable objects at a given cursor location — including overlapping or occluded faces — by presenting them in a small pop-up candidate list. Clicking on a location where multiple faces share the same screen position will repeatedly snap to the topmost (exterior) face by default. That's the trap the scenario describes. Select Other solves this by right-clicking (or using the dedicated command) at that same location and displaying every face candidate stacked at that point. You then simply choose the internal face from the list — no visibility changes required. Option A is correct. Option B is a distractor that sounds technical but misapplies the concept. Component Priority is a selection filter that prioritizes component-level selection over body or face selection — it does not help you reach occluded faces behind another surface. Option C describes a window selection, which captures everything within a rectangular region regardless of occlusion, but it selects based on bounding geometry, not specific face depth — you'd still need to manually deselect the exterior face and may not isolate the exact internal face. Option D directly contradicts the scenario's constraint: isolating a body does change visibility, which the passage explicitly says must be avoided. As a study tip, whenever a Fusion 360 question mentions overlapping or hidden geometry with a constraint against hiding objects, think Select Other first — it's specifically designed for that exact workflow.

Question 10

A designer has already selected four bodies. A fifth body must be added and one of the original four must be removed without clearing the other selections.

Which workflow accomplishes this most directly on a Windows workstation?

  1. Isolate the fifth body, select the unwanted body, and then choose Unisolate
  2. Click the fifth body to add it, then right-click the unwanted body and choose Deselect
  3. Enable Body Priority, click the fifth body, and then click the unwanted selected body
  4. Hold Ctrl, click the fifth body, and Ctrl-click the unwanted selected body (correct answer)
Explanation: When working with multi-body selections in Fusion 360, the key skill being tested here is how to modify an existing selection set — adding one item and removing another — without starting over. Think of the Ctrl key as your selection toggle: holding Ctrl while clicking any object adds it to the current selection if unselected, or removes it if already selected. That toggle behavior is exactly why D is correct. Holding Ctrl and clicking the fifth body adds it to your four existing selections. Then, while still holding Ctrl, clicking the already-selected body deselects it alone, leaving the other three untouched. Two clicks, no disruption to the rest of your selection — clean and direct. Option A misunderstands what Isolate does. Isolating a body is a visibility tool for focusing your viewport, not a selection mechanism. Using Unisolate afterward doesn't restore a prior selection state — it just makes hidden bodies visible again. Option B is tempting but wrong in a critical way: clicking the fifth body without holding Ctrl replaces your entire current selection with just that one body. You'd lose all four original selections instantly. Even if right-click offered a "Deselect" option, you'd have already lost your work by that first bare click. Option C introduces a fictitious feature. "Body Priority" is not a selection mode in Fusion 360 — this is a distractor designed to sound plausible using technical-sounding terminology. Study tip: Whenever a Fusion 360 question involves modifying a selection, think Ctrl first. It's the universal toggle for adding/removing items without clearing the set, and this pattern appears across many Fusion 360 workflows.
