A SolidWorks part must have a hole diameter that is always 10% of the bounding box width. The bounding box width is exposed as which type of SolidWorks property?
Answer: A system-defined mass property (e.g., 'SW-Bounding box width')
SolidWorks provides built-in system properties like 'SW-Bounding box width' that can be referenced in equations or custom properties.
Which of the following correctly describes a 'linked value' in a SolidWorks sketch?
Answer: A named sketch dimension that shares its value with other dimensions bearing the same name, acting like a local variable
Linked values let you name a sketch dimension so that all sketch dimensions sharing that name stay equal, functioning as a local parametric variable within the sketch.
You are building a parametric fastener library in SolidWorks. Which combination of tools best supports fully equation-driven configurations?
Answer: Design tables + global variables + equations
Design tables define configuration-specific values, global variables centralize key parameters, and equations propagate those parameters throughout the model geometry.
In SolidWorks equations, what is the effect of placing a comment using the single-quote (') character?
Answer: Everything after the single quote on that line is treated as a comment and ignored by the solver
In the SolidWorks equation editor, a single quote (') starts an inline comment; the solver ignores all text following it on the same line.
When exporting SolidWorks equations to a text file, which file extension is typically used?
Answer: .eqn
SolidWorks saves exported equation files with the .eqn extension, which can later be imported into other parts or assemblies.
A dimension in a SolidWorks sketch is 'over-defined' after you add an equation to it. What is the most likely cause?
Answer: The dimension is already fully defined by other sketch relations or dimensions, creating a conflict with the equation
Over-definition occurs when a dimension is constrained by both an equation and existing geometric relations or other dimensions simultaneously.
Which SolidWorks equation function computes the natural logarithm of a value?
Answer: ln()
ln(x) returns the natural logarithm (base e) in SolidWorks equations, while log() returns the base-10 logarithm.
