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

Running Mass Properties again from the Evaluate tab recalculates based on the current material definitions of all components.

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

The 'Override Mass Properties' checkbox in the Mass Properties dialog lets you specify custom density, mass, or center of mass values.

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

By default, the moment of inertia is reported relative to the assembly's origin coordinate system.

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 applies a default density and displays a warning that some components lack assigned materials.

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 mass properties are user-defined overrides entered manually, while computed properties derive from the part's geometry and material density.
