In mechanical CAD, what does GD&T stand for?
Answer: Geometric Dimensioning and Tolerancing
GD&T stands for Geometric Dimensioning and Tolerancing, the standard system for defining allowable variation in part geometry.
Which GD&T symbol represents 'flatness' on a mechanical drawing?
Answer: Two parallel horizontal lines
Flatness is represented by two parallel horizontal lines in GD&T and controls how flat a surface must be.
In Autodesk Inventor or SolidWorks, what is a 'mate' constraint used for when assembling parts?
Answer: Defining a geometric relationship that positions two parts relative to each other
Mate constraints in mechanical CAD assemblies define the positional and angular relationships between two components.
What is a bill of materials (BOM) in the context of a mechanical CAD assembly drawing?
Answer: A structured list of all parts and components in an assembly with quantities
A BOM is a structured table in an assembly drawing listing every part, its part number, description, and quantity required.
Which drawing view type in mechanical CAD shows the interior features of a part by cutting through it with a defined cutting plane?
Answer: Section view
A section view reveals internal features of a part by showing the cross-section along a defined cutting plane.
In CAD-based manufacturing (CAM), what does the term 'toolpath' refer to?
Answer: The programmed trajectory a cutting tool follows to machine a part
A toolpath is the defined trajectory generated in CAM software that the cutting tool follows to remove material and create the part.
