In CAD assembly modeling, a 'mate' constraint between two flat faces makes them:
Answer: Coplanar and facing each other
A mate constraint in CAD assembly aligns two faces coplanar and facing (opposing normal directions), simulating physical contact between parts.
The title block of an engineering drawing typically does NOT include:
Answer: Customer's bank account
Title blocks contain part name, number, material, scale, drawing number, revision, company name, and drafter information — not financial data.
In GD&T, flatness tolerance controls:
Answer: How flat a surface is (with no datum reference)
Flatness in GD&T controls all points on a surface lying within two parallel planes separated by the tolerance value; it requires no datum reference.
A bill of materials (BOM) in a CAD assembly drawing lists:
Answer: All component parts with quantities, part numbers, and descriptions
A BOM is a structured list of all components in an assembly, including item numbers, quantities, part numbers, descriptions, and often material and supplier information.
The 'feature control frame' in GD&T contains, in order:
Answer: Symbol, tolerance value, datum reference(s)
A GD&T feature control frame reads left to right: geometric characteristic symbol, tolerance value (with any modifiers), then primary/secondary/tertiary datum references.
In CAD, 'extrude' and 'revolve' are examples of:
Answer: Feature-based modeling operations that create 3D geometry from 2D sketches
Extrude and revolve are sketch-based modeling operations: extrude pushes a 2D profile along an axis, while revolve rotates it around an axis to create 3D solid features.
