Multi-body Part Techniques Flashcards

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

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.

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

Answer: Combine (Common)

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

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

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.

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

Answer: Insert Part

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

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

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.

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

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.

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

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.

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

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.

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

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.

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

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.

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

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.

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

Answer: Solid Bodies folder

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

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

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.

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

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.

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

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.

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

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.

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

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.

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

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.

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?

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.

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

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.
