CSWP Assembly Mass Properties Analysis 2

Question 1

In a SolidWorks assembly, when you change the material of a subassembly component, what must you do to update the top-level assembly mass properties?

Accepted Answer

Run Mass Properties again from the Evaluate tab

Answer

Rebuild the assembly using Ctrl+Q

Answer

Re-open the assembly file

Answer

Update the Bill of Materials

Question 2

Which SolidWorks option allows you to override the density used in a mass properties calculation without changing the part's assigned material?

Accepted Answer

Override Mass Properties in the Mass Properties dialog

Answer

Edit Material dialog

Answer

Configuration Properties

Answer

Appearance manager

Question 3

When SolidWorks calculates the moment of inertia for an assembly, which reference frame is used by default?

Accepted Answer

The assembly origin

Answer

The center of mass of the assembly

Answer

The first component's origin

Answer

The bounding box center

Question 4

A SolidWorks assembly has components with no material assigned. How does this affect the Mass Properties result?

Accepted Answer

SolidWorks uses a default density and warns the user

Answer

SolidWorks uses air density for those parts

Answer

SolidWorks skips those components entirely

Answer

SolidWorks reports zero mass for the entire assembly

Question 5

What is the primary difference between 'Assigned mass properties' and 'Computed mass properties' in SolidWorks?

Accepted Answer

Assigned values are manually entered overrides; computed values are geometry-based calculations

Answer

Assigned values come from material databases; computed values are estimated

Answer

Computed values require purchased licenses; assigned values are free

Answer

Assigned values apply only to sheet metal; computed values apply to solids

Question 6

In which SolidWorks dialog can you select a custom coordinate system to report the center of mass relative to a user-defined reference frame?

Accepted Answer

Mass Properties dialog using the 'Report coordinate values relative to' dropdown

Answer

Mate Properties dialog

Answer

Section Properties dialog

Answer

Simulation Study Properties

Question 7

How does suppressing a component in a SolidWorks assembly affect the mass properties calculation?

Accepted Answer

The suppressed component is excluded from mass properties

Answer

The suppressed component retains its mass contribution

Answer

The suppressed component is replaced with a point mass

Answer

SolidWorks throws an error and cannot calculate mass
