Q1: What are parametric drafting techniques in AutoCAD? Ans: Parametric drafting techniques in AutoCAD involve using parameters, constraints, and parametric relationships to create intelligent objects whose sizes and shapes can be controlled and modified easily. Q2: What is a parameter in AutoCAD? Ans: In AutoCAD, a parameter is a user-defined variable that represents a value, such as a length, angle, or text. Parameters can be assigned to objects to control their properties and dimensions. Q3: How do constraints work in AutoCAD? Ans: Constraints in AutoCAD are geometric relationships that restrict the movement and behavior of objects. They ensure that objects maintain specific distances, angles, or alignments relative to other objects or reference points. Q4: What is a parametric relationship? Ans: A parametric relationship is a rule or equation that defines how parameters and constraints interact to maintain the desired behavior of an object. It ensures that changes to one parame
