CSWP Multi-body Part Techniques — Questions and Answers

Question 1: When using the Combine feature with the 'Subtract' operation, which body is removed from which?

The tool body is subtracted from the main body (Correct answer)
The main body is subtracted from the tool body
Both bodies are merged and overlapping volume is removed
The smaller body is always subtracted from the larger body

Correct answer: The tool body is subtracted from the main body

In Combine-Subtract, the tool body's volume is removed from the main body, leaving only the main body with a cavity.

Question 2: Which feature is used to create a new solid body by intersecting two existing bodies in a multi-body part?

Combine (Common) (Correct answer)
Combine (Subtract)
Split
Move/Copy Bodies

Correct answer: Combine (Common)

Combine with the 'Common' option retains only the overlapping (intersecting) volume between selected bodies.

Question 3: In a multi-body part, what does the 'Merge result' checkbox control in a boss/extrude feature?

Whether the new extrusion merges with existing solid bodies it touches (Correct answer)
Whether sketch geometry is absorbed into the model
Whether the feature is suppressed after creation
Whether the extrusion uses thin-feature mode

Correct answer: Whether the new extrusion merges with existing solid bodies it touches

'Merge result' determines if an overlapping extrusion joins with adjacent bodies or remains a separate body.

Question 4: Which SolidWorks tool allows you to propagate design changes from a master multi-body part to derived part files?

Insert Part (Correct answer)
Split
Save Bodies
Combine

Correct answer: Insert Part

Insert Part embeds a reference to the master body, so downstream parts update when the master changes.

Question 5: When you use 'Save Bodies' to export solid bodies from a multi-body part, what happens to the resulting files by default?

They are saved as separate part files with an external reference to the parent (Correct answer)
They are saved as assembly files
They are saved as STL exports with no parametric data
They are saved as configurations within the same file

Correct answer: They are saved as separate part files with an external reference to the parent

Save Bodies creates new .SLDPRT files that maintain an external reference back to the originating multi-body part.

Question 6: What is the purpose of the 'Scope' option available in multi-body features such as fillets and chamfers?

To limit which solid bodies the feature applies to (Correct answer)
To set the display color of the feature
To define the sketch plane for the feature
To control the rebuild order of bodies

Correct answer: To limit which solid bodies the feature applies to

Scope lets you select specific bodies to receive the fillet or chamfer, excluding other bodies in the same part file.

Question 7: In SolidWorks, when a multi-body part is inserted into an assembly, how many components does it count as?

One component regardless of how many solid bodies it contains (Correct answer)
One component per solid body
One component per feature
Two components: one for the part and one for each body

Correct answer: One component regardless of how many solid bodies it contains

A multi-body part file is treated as a single component in the assembly, even if it contains multiple solid bodies.

Question 8: Which technique is best for designing a plastic enclosure where the top and bottom halves share exact mating geometry?

Model both halves as bodies in a single multi-body part, then use Save Bodies (Correct answer)
Model each half in a separate part file from the start
Create an assembly and use assembly features to split
Use a drawing template with two sheet configurations

Correct answer: Model both halves as bodies in a single multi-body part, then use Save Bodies

Modeling both halves together ensures perfect geometry match before splitting into individual part files via Save Bodies.

Question 9: What is a key advantage of the 'Indent' feature over the standard Combine-Subtract when creating mating features between bodies?

Indent adds a clearance or thickness offset during the subtraction automatically (Correct answer)
Indent merges bodies permanently while Subtract keeps them separate
Indent only works on sheet metal bodies
Indent creates a pattern of cuts while Subtract creates one

Correct answer: Indent adds a clearance or thickness offset during the subtraction automatically

The Indent feature subtracts the tool body shape from the target body while adding a user-defined clearance gap, ideal for fit tolerances.

Question 10: When using the Split feature with a sketched split line, which result bodies can you choose to keep?

Any combination of the resulting bodies using the checkboxes in the resulting bodies list (Correct answer)
Only the larger resulting body
Only the body on the sketch plane side
All resulting bodies must be kept; none can be discarded

Correct answer: Any combination of the resulting bodies using the checkboxes in the resulting bodies list

After splitting, SolidWorks lists all resulting bodies and lets you check or uncheck which ones to retain.

Question 11: How does 'Local Operations' improve performance when working with multi-body parts containing many bodies?

It rebuilds only the affected body instead of recalculating all bodies in the part (Correct answer)
It offloads computation to the graphics card
It compresses body geometry to reduce file size
It converts complex bodies to mesh for faster display

Correct answer: It rebuilds only the affected body instead of recalculating all bodies in the part

Local Operations restricts the rebuild scope to the selected body, significantly reducing rebuild time in complex multi-body parts.

Question 12: In the FeatureManager, individual bodies in a multi-body part are listed under which folder?

Solid Bodies folder (Correct answer)
Surface Bodies folder
Bodies folder
Components folder

Correct answer: Solid Bodies folder

All solid bodies created in a multi-body part appear in the Solid Bodies folder in the FeatureManager design tree.

Question 13: Which workflow is most appropriate for a multi-body weldment where individual members need separate cut lists and BOM entries?

Weldment feature with structural members auto-grouped by cut-list folder (Correct answer)
Save Bodies to separate parts with manual BOM entry
Assembly-driven weldment using configurations
Multi-body part with manually named bodies and drawing notes

Correct answer: Weldment feature with structural members auto-grouped by cut-list folder

SolidWorks Weldments automatically generates a cut list by grouping identical structural members, which feeds directly into drawings and BOMs.

Question 14: When mirroring a body with 'Mirror Bodies,' what option controls whether the mirrored copy is a separate body or merged with the original?

The 'Merge solid bodies' checkbox in the Mirror feature PropertyManager (Correct answer)
The 'Create derived part' toggle
The sketch symmetry constraint applied before mirroring
The configuration active at the time of mirroring

Correct answer: The 'Merge solid bodies' checkbox in the Mirror feature PropertyManager

Checking 'Merge solid bodies' in the Mirror feature joins the mirror result with the source body; unchecking keeps them as distinct bodies.

Question 15: What happens to the original bodies after a Combine-Add operation in SolidWorks?

They are consumed into a single merged body and no longer exist individually (Correct answer)
They remain as separate bodies alongside the new combined body
They are moved to a suppressed state
They are exported automatically to separate files

Correct answer: They are consumed into a single merged body and no longer exist individually

Combine-Add merges all selected bodies into one body; the individual source bodies are consumed and replaced by the single result.

Question 16: A designer needs to model foam inserts that perfectly conform to the interior of a plastic housing. Which multi-body technique is most efficient?

Model the housing, then use Combine-Subtract or Indent to carve the foam body using the housing geometry (Correct answer)
Model the foam independently with separate measurements
Import the housing as a reference body from an assembly
Use a surface offset from the housing and thicken it

Correct answer: Model the housing, then use Combine-Subtract or Indent to carve the foam body using the housing geometry

Using the existing housing body as a cutting tool via Indent or Subtract ensures the foam geometry exactly matches the housing interior without re-modeling it.

Question 17: Which property must be assigned to each body in a multi-body part for individual bodies to display different materials in a drawing BOM?

Material applied per-body via the Solid Bodies folder right-click menu (Correct answer)
Material assigned at the part document level
Material configured in the drawing format
Material listed as a custom property in the part's Summary tab

Correct answer: Material applied per-body via the Solid Bodies folder right-click menu

Right-clicking a body in the Solid Bodies folder lets you assign a unique material per body, which can then be referenced in cut lists or BOMs.

Question 18: What is the effect of checking 'Absorb sketches' when inserting a part into a multi-body part file?

Sketches from the inserted part are moved into the host part's FeatureManager and become editable (Correct answer)
Sketches are deleted from both the source and host files
Sketches remain in the inserted part and are not accessible in the host
Sketches are converted to 3D curves in the host part

Correct answer: Sketches from the inserted part are moved into the host part's FeatureManager and become editable

Absorb sketches brings the source part's sketches into the host file's FeatureManager so they can be used to drive new features.

Question 19: During a CSWP exam scenario, you are told to use a plane to split a body and keep only the upper portion. Which feature accomplishes this?

Split, selecting the plane as the trim tool and deselecting the lower body (Correct answer)
Extruded Cut using a sketch on the plane
Combine-Subtract using the lower body as the tool
Delete Face applied to all lower faces

Correct answer: Split, selecting the plane as the trim tool and deselecting the lower body

The Split feature accepts a plane as its trimming tool and lets you choose which resulting bodies to keep via checkboxes.

Question 20: In a multi-body part, how can you rename a solid body to something meaningful like 'Housing_Top'?

Slow double-click the body name in the Solid Bodies folder in the FeatureManager (Correct answer)
Right-click and select 'Properties,' then edit the FileName field
Edit the body's first feature and change the description
Rename is not possible; bodies use auto-generated names only

Correct answer: Slow double-click the body name in the Solid Bodies folder in the FeatureManager

A slow double-click (or right-click > Rename) on the body in the Solid Bodies folder allows you to type a custom name for that body.

Question 21: Which statement accurately describes 'Patterning Bodies' versus 'Patterning Features' in a multi-body part?

Patterning bodies copies the entire body geometry, rebuilding faster since individual features are not re-solved for each instance (Correct answer)
Patterning bodies is slower because each body is saved as a separate file during the pattern
Patterning features is always faster than patterning bodies regardless of complexity
Patterning bodies requires a separate assembly to manage the instances

Correct answer: Patterning bodies copies the entire body geometry, rebuilding faster since individual features are not re-solved for each instance

Body patterns copy the final body geometry directly, avoiding recalculation of every feature for each instance, which speeds up rebuild significantly.
