q1 / 5
1- which of the following statements about parametric sketching is false?
a. many sketches are used as the basis for generating three-dimensional solid geometry
b. a parametric sketch is a collection of two-dimensional geometric entities related to each other through constraints
c. when modeling complex parts, multiple simple sketches are generally easier to manage than a single complex sketch
d. when defining the shape of a sketch, before the application of constraints, sketches must be drawn accurately

Explanation:

To determine the false statement about parametric sketching:

• Option A: Sketches are often used for 3D solid geometry generation (true).
• Option B: Parametric sketches have 2D entities with constraints (true, by definition).
• Option C: Multiple simple sketches are easier to manage than one complex sketch for complex parts (true, as complexity is reduced).
• Option D: In parametric sketching, before applying constraints, sketches don't need to be drawn accurately (constraints define accuracy later), so this is false.

Answer:

D. When defining the shape of a sketch, before the application of constraints, sketches must be drawn accurately
