Question

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

Correct answer (A) boundary representation (B-rep) Solution Solid modeling in CAD involves representing the entire volume of an object. The two primary methods for solid modeling are: 1. Boundary Representation (B-rep) : Describes a solid by its bounding surfaces (faces, edges, vertices). 2. Constructive Solid Geometry (CSG) : Builds complex solids using Boolean operations on primitive shapes. Bezier curves, B-splines, and NURBS are mathematical representations used for curve and surface modeling, which can be part of a B-rep model but are not solid modeling techniques themselves. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
