Part Modelling In SOLIDWORKS

A: A. That drives unnecessary cost and inspection burden because ISO 2768 exists to avoid blanket tight tolerances. B. That breaks traceability because manufacturing assumptions aren't controlled in the design data. C. That imports tribal knowledge that may not match the contractual standard. D. This aligns the model and drawing so default tolerances are applied consistently where none are called out.

A: A. That leaves the stress riser in the solid model so downstream FEA underpredicts fatigue risk. B. That increases peak stress under bending compared to a radius for the same envelope. C. That creates a mismatch between analysis, drawing, and as-built geometry. D. This reflects the real geometry and improves fatigue life prediction without manufacturing surprise.

A: A. That hides design intent loss and often breaks mates and drawings later. B. That wastes time and increases the risk of introducing silent geometry changes. C. That locks the model and prevents legitimate future variation. D. This maintains parametric behavior so geometry updates predictably with the new input.

A: A. That often ignores how the part is actually located in the assembly. B. That creates unstable datums because fillets vary with process. C. That assumes the CAD origin has functional meaning when it usually doesn't. D. This ties tolerance control to real assembly interfaces as the standard intends.
