In a SolidWorks assembly mass properties dialog, what does the 'Accuracy' slider control?
Answer: The tessellation refinement used to approximate curved surface volumes
The Accuracy slider adjusts the mesh tessellation quality used to approximate volume for curved geometry, trading speed for precision.
A CSWP problem states that the density of a custom material is 7,850 kg/m³. If you are working in the MMGS unit system, what density value should you enter in SolidWorks?
Answer: 0.00785 g/mm³
7,850 kg/m³ converts to 0.00785 g/mm³ because 1 kg/m³ = 0.000001 g/mm³, so 7,850 × 0.000001 = 0.00785 g/mm³.
Which SolidWorks tool is specifically designed to automatically update a linked mass value in a drawing annotation whenever the assembly mass changes?
Answer: Bill of Materials with mass column
A Bill of Materials with a mass column linked to the SolidWorks Mass property automatically reflects updated masses when the drawing is regenerated.
In SolidWorks, which assembly-level operation would cause the center of mass to shift without changing the total mass of the assembly?
Answer: Moving a component to a different position using mates
Repositioning a component via mates changes where its mass is located spatially, shifting the assembly's center of mass without altering total mass.
When a SolidWorks part contains multiple bodies (multibody part), how does the Mass Properties tool handle them when the part is used in an assembly?
Answer: All solid bodies in the part contribute to the assembly mass
All solid bodies within a multibody part contribute their individual volumes and masses to the assembly's total mass properties.
For CSWP purposes, if you need to verify your answer for assembly mass to 2 decimal places, which setting should you check in SolidWorks?
Answer: Tools > Options > Document Properties > Units — set decimal places to 2 or higher
Document Properties > Units controls the number of decimal places displayed throughout the document, including Mass Properties results.
In SolidWorks, what happens to the mass properties of an assembly when you create an exploded view?
Answer: Mass properties remain unchanged because no geometry or material is altered
An exploded view is a visual display state only; it does not alter geometry or material, so mass properties are completely unaffected.
