Question 1Inventor part modeling

In an Inventor part file, which sketch constraint makes a line segment parallel to the horizontal or vertical axis of the sketch coordinate system?

  1. Coincident constraint
  2. Symmetric constraint
  3. Tangent constraint
  4. Horizontal or Vertical constraint Correct answer.

Explanation

The Horizontal and Vertical constraints align a line with the sketch X or Y axis and are applied automatically when the line is drawn close to alignment. They differ from geometric relations between two entities, such as coincidence or tangency.

Question 2Inventor part modeling

What does the Extents option 'Distance' control when creating an extrusion in a part?

  1. The taper angle applied to side faces
  2. The number of copies created along the axis
  3. The total depth measured from the sketch plane Correct answer.
  4. The fillet radius applied to the outer edges

Explanation

With the Distance extents type, the extrusion depth is a single value measured from the sketch plane in the chosen direction. Other extents types reference existing geometry rather than a fixed numeric depth.

Question 3Inventor part modeling

Which work feature is used to create a plane offset a specified distance from an existing face or plane?

  1. Tangent plane
  2. Angle plane
  3. Midplane between two planes
  4. Offset plane from a plane Correct answer.

Explanation

An offset work plane is defined by an existing planar face or work plane plus a numeric distance. The other plane types require different reference geometry such as an axis, a point, or a second plane.

Question 4Inventor part modeling

What is the primary purpose of a Revolve feature in part modeling?

  1. Lofting between several unrelated profiles
  2. Rotating a profile about an axis to create a solid Correct answer.
  3. Sweeping a profile along a closed path
  4. Thickening a surface into a shell

Explanation

Revolve spins a closed profile around a chosen axis by a specified angle to generate a solid. The profile must lie on one side of the axis so the resulting geometry does not self-intersect.

Question 5Inventor part modeling

In a part file, which feature removes material by cutting a profile through or into existing geometry?

  1. Chamfer
  2. Extrude with the Join operation
  3. Extrude with the Cut operation Correct answer.
  4. Hole with a counterbore

Explanation

An Extrude feature set to the Cut operation subtracts the swept profile volume from the existing solid. Join adds material, while Hole and Chamfer modify geometry with dedicated parameters.

Question 6Inventor part modeling

Which sketch tool projects existing model edges onto the active sketch plane as reference geometry?

  1. Extend
  2. Trim
  3. Project Geometry Correct answer.
  4. Offset

Explanation

Project Geometry brings selected model edges or vertices onto the sketch plane so they can be referenced by new sketch geometry. The projected curves are associated with the source edges.

Question 7Inventor part modeling

What does the Hole feature's 'Termination' setting of 'Through All' produce?

  1. A hole limited to the first encountered face
  2. A hole that passes through the entire part in the chosen direction Correct answer.
  3. A hole that stops at a specified depth
  4. A hole that follows a curved surface

Explanation

Through All extends the hole until it exits all material in the specified direction, regardless of part thickness. Depth-based termination instead stops at a fixed value.

Question 8Inventor part modeling

Which constraint would you apply to make two circles share the same center point?

  1. Equal
  2. Collinear
  3. Parallel
  4. Concentric Correct answer.

Explanation

The Concentric constraint aligns the centers of two circular or arc entities so they share a common center. Equal only matches radii and does not fix the center location.

Question 9Inventor part modeling

A part must have a rib that follows a curved outer edge with a constant wall thickness. Which feature best creates this?

  1. Coil
  2. Extrude with a symmetric distance
  3. Loft between two sections
  4. Sweep along the edge path with a profile Correct answer.

Explanation

A Sweep drives a profile along a path, so a small cross-section swept along the curved edge yields a rib of uniform thickness. Extrude and Loft cannot follow an arbitrary curved path with constant section.

Question 10Inventor part modeling

You need a work axis through the center of a cylindrical hole. Which selection creates it most directly?

  1. Select the cylindrical face of the hole Correct answer.
  2. Select three non-collinear points
  3. Select two parallel planar faces
  4. Select a sketch line and a plane

Explanation

Selecting a cylindrical or conical face creates a work axis along its centerline automatically. Other reference combinations define axes through intersections or points instead.

Question 11Inventor part modeling

A fillet fails on an edge that meets several other edges at a sharp corner. What is the most appropriate first remedy?

  1. Convert the part to a surface model
  2. Increase the fillet radius substantially
  3. Reduce the radius or reorder the feature so the corner is resolved first Correct answer.
  4. Delete all sketches in the browser

Explanation

Fillet failures at complex corners usually stem from the radius exceeding available space or from feature ordering. Reducing the radius or filleting the intersecting edges earlier often resolves the geometry.

Question 12Inventor part modeling

What is the effect of setting an Extrude feature to the 'Symmetric' direction option?

  1. It extrudes only in the reverse direction
  2. It extrudes half the distance on each side of the sketch plane Correct answer.
  3. It tapers both ends of the extrusion
  4. It creates a mirrored copy of the feature

Explanation

Symmetric distributes the specified total distance equally on both sides of the sketch plane. This is useful when the sketch plane sits at the mid-thickness of the intended part.

Question 13Inventor part modeling

How does the 'To Next' termination differ from 'To Face' in an extrusion?

  1. To Next requires a work plane, while To Face does not
  2. To Next stops at the next face encountered, while To Face stops at a specifically selected face Correct answer.
  3. To Next creates a cut, while To Face creates a join
  4. To Next measures from the origin, while To Face measures from the sketch

Explanation

To Next automatically terminates at the first surface the extrusion meets, whereas To Face requires the user to pick the exact terminating face. To Face is more predictable when several faces lie along the direction.

Question 14Inventor part modeling

A designer wants a pattern of holes that follows a rectangular grid across a plate. Which pattern type fits best?

  1. Circular pattern
  2. Sketch-driven pattern along a spline
  3. Rectangular pattern Correct answer.
  4. Mirror feature

Explanation

A Rectangular pattern repeats a feature in two orthogonal directions with specified spacing and counts. Circular patterns distribute instances around an axis instead.

Question 15Inventor part modeling

Which operation would you choose to combine two separate solid bodies into a single body while keeping all material?

  1. Split
  2. Thicken
  3. Combine with the Cut operation
  4. Combine with the Join operation Correct answer.

Explanation

The Combine feature with the Join operation merges overlapping or touching solid bodies into one continuous body. Cut and Intersect remove material instead.

Question 16Inventor part modeling

What does the 'Taper' angle in an Extrude feature do to the resulting geometry?

  1. Rounds the top edges of the extrusion
  2. Rotates the profile within the sketch plane
  3. Adds a draft only to internal cavities
  4. Slants the side walls relative to the extrusion direction Correct answer.

Explanation

A taper angle inclines the extruded side faces, producing a draft-like shape that narrows or widens along the direction. It does not modify edges or rotate the profile.

Question 17Inventor part modeling

A sketch profile is fully constrained, but the extrusion refuses to build. Which cause is most likely?

  1. The part has more than one work plane
  2. The profile contains an open loop or self-intersecting curve Correct answer.
  3. The sketch uses too many dimensions
  4. The model uses millimeters instead of inches

Explanation

Extrude requires a closed, non-self-intersecting profile; an open or crossing boundary cannot form a solid. Dimension count and unit choice do not prevent feature creation.

Question 18Inventor part modeling

Which sketch technique best captures design intent so that a slot stays centered on a plate when its width changes?

  1. Drawing the slot freehand without constraints
  2. Dimensioning the slot to the plate edges with symmetric constraints about a center plane Correct answer.
  3. Applying a tangent constraint between the slot and the plate edge
  4. Locking every slot vertex with fixed constraints

Explanation

Symmetric constraints about a center plane keep the slot centered while dimensions control its size, so edits preserve the intended relationship. Fixed constraints prevent the geometry from adapting.

Question 19Inventor part modeling

What is the difference between the Equal constraint and the Symmetric constraint in a sketch?

  1. Equal mirrors position, while Symmetric matches size
  2. Equal applies only to arcs, while Symmetric applies only to lines
  3. Equal matches size, while Symmetric mirrors position about a line Correct answer.
  4. Equal requires a work plane, while Symmetric does not

Explanation

Equal forces selected entities to share the same length or radius. Symmetric positions two entities at mirrored distances about a selected symmetry line.

Question 20Inventor part modeling

You need a counterbored hole with a specific depth for the larger diameter. Which Hole feature option controls the larger recessed diameter?

  1. The simple hole diameter
  2. The point placement
  3. The counterbore diameter and depth Correct answer.
  4. The thread designation

Explanation

A counterbore hole type adds a larger cylindrical recess above the main hole, and its diameter and depth are set independently. The simple hole diameter governs the through portion.

Question 21Inventor part modeling

A pattern of a hole feature is created, then the original hole is moved. What happens to the patterned instances by default?

  1. They remain at their original coordinates
  2. They convert to separate sketch points
  3. They update to follow the new position of the parent feature Correct answer.
  4. They are deleted automatically

Explanation

Pattern instances are associative to the parent feature, so moving or editing the parent updates all instances. This associativity is central to parametric modeling.

Question 22Inventor part modeling

Which approach creates a shelled enclosure with uniform wall thickness from a solid block?

  1. Apply a large fillet to all edges
  2. Use the Mirror feature about the midplane
  3. Create a rectangular pattern of the block
  4. Apply the Shell feature and remove the open face Correct answer.

Explanation

The Shell feature hollows a solid, leaving walls of a specified uniform thickness, and selected faces can be removed to open the cavity. Fillets and patterns do not hollow the body.

Question 23Inventor part modeling

A loft between two rectangular sections produces a twisted shape. Which setting most directly corrects the twist?

  1. Adjusting the mapping of the section points or adding rails Correct answer.
  2. Applying a chamfer to the result
  3. Increasing the extrusion taper
  4. Changing the part units

Explanation

Loft twist usually results from mismatched point mapping between sections, which can be corrected by adjusting the mapping or adding rails to guide the transition. Taper, units, and chamfers do not control loft correspondence.

Question 24Inventor part modeling

Two extrusions overlap, and a later feature must remove only the shared volume. Which Combine operation achieves this?

  1. Join
  2. Split
  3. Intersect Correct answer.
  4. Cut

Explanation

Combine with the Intersect operation keeps only the volume common to both bodies and discards the rest. Join merges everything, while Cut subtracts one body from another.

Question 25Inventor part modeling

A rib feature must be added to a thin-walled casting so that it merges cleanly with the walls. Which setting is most important to ensure proper merging?

  1. The number of pattern instances
  2. The taper angle of an unrelated extrusion
  3. The document unit precision
  4. The rib thickness direction and the option to extend into the base Correct answer.

Explanation

Rib features need the correct thickness direction and an option that extends the rib into the adjacent material so the new volume fuses with the walls. Without proper merging, the rib may fail or leave gaps.

Question 26Inventor part modeling

Which sketch constraint makes a line's length stay fixed when other geometry changes?

  1. Equal constraint
  2. Tangent constraint
  3. Fix constraint Correct answer.
  4. Coincident constraint

Explanation

The Fix constraint locks a sketch entity to its current position, size, and orientation, so its length cannot change when other geometry is edited. Equal makes two entities match each other rather than fixing a value, and Coincident and Tangent only relate entities to one another.

Question 27Inventor part modeling

Which sketch tool adds a reference line that is not included in the extruded profile?

  1. Projected edge
  2. Sketch point
  3. Construction geometry Correct answer.
  4. Centerline of a revolve

Explanation

Construction geometry is sketch geometry that is used for alignment and constraints but is ignored when a profile is selected for a feature. This lets a designer build symmetry lines and reference frames without affecting the resulting solid.

Question 28Inventor part modeling

What does the Revolve feature require in addition to a closed profile?

  1. A second profile on a parallel plane
  2. An axis of revolution Correct answer.
  3. A work plane offset from the profile
  4. A shell thickness value

Explanation

Revolve sweeps a profile around an axis, so an axis of revolution must be defined, either from sketch geometry or from a model edge or work axis. Without an axis the feature has no rotational reference and cannot build.

Question 29Inventor part modeling

Which feature creates a solid by sweeping a profile along a path while allowing the profile to change between multiple sections?

  1. Emboss
  2. Loft Correct answer.
  3. Sweep
  4. Coil

Explanation

Loft builds a solid by blending between two or more section profiles, so the cross-section can change shape along the length. Sweep uses one profile carried along a path without changing its shape.

Question 30Inventor part modeling

Which pattern type distributes instances around a central axis?

  1. Circular pattern Correct answer.
  2. Sketch-driven pattern
  3. Mirror feature
  4. Rectangular pattern

Explanation

A circular pattern rotates copies of a feature about an axis by a specified angle or count. Rectangular patterns distribute instances along two linear directions instead.

Question 31Inventor part modeling

Which tool measures the distance between two selected faces in an assembly or part?

  1. Cross section
  2. Measure Correct answer.
  3. Inspect
  4. Analyze interference

Explanation

The Measure tool reports distance, angle, length, area, and other values between selected entities. It is the direct way to check clearance or verify that a modeled distance matches intent.

Question 32Inventor part modeling

What is the purpose of the Extrude 'Distance' field when the direction is set to 'One Side'?

  1. It sets the angular rotation of the profile.
  2. It sets the total depth of the extrusion in the chosen direction. Correct answer.
  3. It sets half the depth on each side of the sketch plane.
  4. It sets the number of copies created.

Explanation

With a one-side direction, the distance value defines how far the profile is extruded along the chosen direction from the sketch plane. The symmetric option, by contrast, splits that value across both sides.

Question 33Inventor part modeling

Which file type stores a single part in Autodesk Inventor?

  1. .idw
  2. .ipt Correct answer.
  3. .iam
  4. .ipn

Explanation

An .ipt file is an Inventor part file containing sketches, features, and solid bodies. Assembly, drawing, and presentation files use different extensions.

Question 34Inventor part modeling

A designer needs a rectangular pocket with vertical walls and a flat bottom at a fixed depth. Which feature is most direct?

  1. Rib
  2. Extrude cut with a distance termination Correct answer.
  3. Revolve cut
  4. Hole with a counterbore

Explanation

An extrude cut removes material from an existing solid down to the specified distance, producing vertical walls and a flat bottom that matches the sketch profile. This matches the described pocket exactly.

Question 35Inventor part modeling

A fillet radius of 8 mm is requested on an edge, but the adjacent face is only 6 mm wide. What is the most likely result?

  1. The fillet builds and automatically trims the face to 2 mm.
  2. The fillet builds and converts the face into a construction surface.
  3. The fillet fails because the radius exceeds the available face width. Correct answer.
  4. The fillet builds with a reduced radius of 6 mm automatically.

Explanation

A fillet needs enough adjacent material to accommodate the radius; when the radius is larger than the available face, the operation cannot resolve the geometry and the feature fails. The designer must reduce the radius or change the adjacent geometry.

Question 36Inventor part modeling

How does a Sweep feature differ from an Extrude feature?

  1. Sweep requires two profiles, while Extrude requires three.
  2. Sweep removes material only, while Extrude adds material only.
  3. Sweep follows a defined path, while Extrude moves the profile linearly along its normal. Correct answer.
  4. Sweep works only on curved sketches, while Extrude works only on straight sketches.

Explanation

Sweep carries a profile along a user-defined path, which may be curved, so the resulting solid follows that path. Extrude translates the profile in a straight line perpendicular to the sketch plane.

Question 37Inventor part modeling

A part must be hollowed with 3 mm walls, but one face must remain open. Which setting achieves this?

  1. Shell with uniform thickness only
  2. Hole with a through-all termination
  3. Chamfer on the perimeter
  4. Shell with the open face removed Correct answer.

Explanation

The Shell feature hollows a solid, and removing a face from the selection leaves that side open while the remaining walls get the specified thickness. Selecting no open face produces a fully closed hollow body.

Question 38Inventor part modeling

Which work feature is created automatically when a cylindrical face is selected with the work axis tool?

  1. A work axis through the cylinder's center Correct answer.
  2. A work point at the cylinder's midpoint
  3. A work plane tangent to the cylinder
  4. A work plane perpendicular to the cylinder's axis

Explanation

Selecting a cylindrical face creates a work axis that coincides with the cylinder's centerline. This axis can then be used for patterns, mates, or additional work features.

Question 39Inventor part modeling

What does the 'Join' operation in the Combine feature do?

  1. It subtracts the tool body volume from the target body.
  2. It keeps only the volume shared by both bodies.
  3. It adds the volume of the tool body to the target body. Correct answer.
  4. It deletes the target body and keeps the tool body.

Explanation

Join merges the tool body into the target body so the resulting solid contains the combined material of both. Cut removes the tool volume, and Intersect keeps only the overlapping region.

Question 40Inventor part modeling

A hole must be placed at the center of a rectangular plate and stay centered if the plate's dimensions change. Which approach best preserves that intent?

  1. Place the hole with a sketch point and no constraints.
  2. Place the hole using absolute coordinates.
  3. Dimension the hole from one corner with fixed values.
  4. Constrain the hole sketch point to the midpoints of two perpendicular edges. Correct answer.

Explanation

Constraining the hole point to midpoints of perpendicular edges ties its location to the plate's center, so resizing the plate keeps the hole centered. Absolute or corner-based dimensions would hold fixed offsets instead.

Question 41Inventor part modeling

What does the 'To' termination option in an Extrude feature require?

  1. A selected face or surface that the extrusion stops at Correct answer.
  2. A numeric distance value
  3. A selected axis of rotation
  4. A specified taper angle

Explanation

The To termination extends the extrusion until it reaches a selected face or surface, so the resulting depth adapts to that geometry. This differs from a distance termination, which uses a fixed numeric value.

Question 42Inventor part modeling

A pattern of a feature is created, and the original feature is later suppressed. What happens to the pattern?

  1. The pattern instances are also suppressed because they depend on the parent feature. Correct answer.
  2. The pattern automatically converts to a mirror.
  3. The pattern instances become free-floating bodies.
  4. The pattern instances remain because they are independent solids.

Explanation

Pattern instances are derived from the parent feature, so suppressing the parent removes the source geometry and the pattern can no longer build, effectively suppressing its instances. The dependency must be resolved by restoring or replacing the parent feature.

Question 43Inventor part modeling

Which sketch tool would you use to offset a closed profile inward by a fixed distance?

  1. Extend
  2. Fillet
  3. Trim
  4. Offset Correct answer.

Explanation

The Offset tool creates a parallel copy of selected sketch geometry at a specified distance, which is useful for wall thicknesses and clearance profiles. Trim, Extend, and Fillet modify existing geometry rather than creating a parallel copy.

Question 44Inventor part modeling

A designer needs a raised boss with a drafted side wall on top of a plate. Which combination of settings achieves this in one extrusion?

  1. Through All termination with a negative taper
  2. Distance termination with a positive taper angle Correct answer.
  3. Symmetric termination with zero taper
  4. To Next termination with zero taper

Explanation

A distance termination sets the boss height, and a positive taper angle slopes the side walls inward as the extrusion proceeds, producing the draft. Combining termination with a taper angle is the direct way to add draft during extrusion.

Question 45Inventor part modeling

What does the 'Minimum Remaining Wall' setting in the Hole feature control?

  1. The minimum diameter of the hole
  2. The minimum number of hole instances in a pattern
  3. The minimum thread depth of a tapped hole
  4. The minimum material left between the hole bottom and the far face Correct answer.

Explanation

The minimum remaining wall value ensures that a hole termination leaves at least that much material before breaking through the opposite face. It is used to keep blind holes safely short of the far surface.

Question 46Inventor part modeling

A loft between a small circle and a large square produces an unexpected twist. Which control most directly resolves the twist?

  1. Increasing the number of sections
  2. Adjusting the loft rails
  3. Applying a taper angle
  4. Changing the section mapping or adding a rail Correct answer.

Explanation

Twist in a loft usually comes from mismatched correspondence between section vertices, so adjusting the mapping or adding rails that guide the blend corrects the alignment. Adding sections or a taper does not fix the correspondence itself.

Question 47Inventor part modeling

A model must show a knurled grip on a cylindrical handle with many small ridges. Which approach is most efficient for performance?

  1. Model every ridge as a separate extrusion and pattern them.
  2. Model the ridges as individual work features.
  3. Model the ridges as a cosmetic or decal texture on the cylindrical face. Correct answer.
  4. Model the ridges with a single swept cut and circular pattern of 200 instances.

Explanation

Representing fine surface detail such as knurling as a cosmetic texture keeps the solid simple, which preserves modeling and drawing performance. Modeling hundreds of tiny ridges creates heavy geometry with little functional benefit.

Question 48Inventor part modeling

An extrusion must stop at a curved surface that it meets at an angle. Which termination is most appropriate?

  1. To Face or To Next Correct answer.
  2. Through All
  3. Symmetric
  4. Distance with a fixed value

Explanation

A To Face or To Next termination lets the extrusion end on the selected curved surface so the resulting end matches that surface. A fixed distance would not follow the curve, and Through All would pass completely through the part.

Question 49Inventor part modeling

A rib is added to a thin-walled casting and must merge with the existing walls. Which setting is most important?

  1. The shell thickness value
  2. The rib thickness direction and the option to extend to the existing body Correct answer.
  3. The taper angle of the rib profile
  4. The number of pattern instances

Explanation

A rib must be given a thickness direction and be allowed to extend into the adjacent walls so it merges into a single solid. Without that merging behavior the rib can remain disconnected or create a thin sliver.

Question 50Inventor part modeling

A part contains an undercut that prevents a straight pull from a mold. Which analysis tool identifies faces that cannot be drafted sufficiently?

  1. Zebra analysis
  2. Draft analysis Correct answer.
  3. Cross-section analysis
  4. Interference analysis

Explanation

Draft analysis colors faces according to their angle relative to a pull direction, revealing faces that would prevent a clean release from the mold. This helps the designer add draft or redesign the undercut before manufacturing.
