GATE 2025 ME – Question 23

Computer Aided Manufacturing and Automation · CAD/CAM and their integration · 1 mark · Multiple choice

In computer aided design (CAD), solid models can be constructed using

  1. boundary representation (B-rep)
  2. Bezier curves
  3. B-splines
  4. nonuniform rational B-splines (NURBS)

Show answer and explanation

Correct answer: (A) boundary representation (B-rep)

Explanation

Solid models are built using representations such as boundary representation (B-rep) and constructive solid geometry. Bezier curves, B-splines and NURBS describe curves and surfaces, not solids as such.
