CAD Geometric Constraints 2

Question 1

What is the key difference between geometric constraints and dimensional constraints in CAD?

Accepted Answer

Geometric constraints define shape relationships; dimensional constraints define size and position numerically

Answer

Geometric constraints are applied first; dimensional constraints are applied last

Answer

Geometric constraints only apply to 2D sketches; dimensional constraints apply to 3D models

Answer

Geometric constraints are permanent; dimensional constraints can be changed

Question 2

What does an 'Equal' constraint do when applied to two lines?

Accepted Answer

Makes them the same length

Answer

Forces them to be parallel

Answer

Aligns them end to end

Answer

Makes them collinear

Question 3

Which constraint ensures a point lies exactly on a curve or line (not necessarily at its endpoint)?

Accepted Answer

On Curve (Point On)

Answer

Coincident

Answer

Pierce

Answer

Fix

Question 4

What is 'over-constraining' in CAD sketching?

Accepted Answer

Applying redundant or conflicting constraints that make the sketch mathematically unsolvable or over-defined

Answer

Applying more constraints than the sketch has elements

Answer

Adding too many dimensions to the model tree

Answer

Using fix constraints on every element

Question 5

Which geometric constraint makes two lines or curves meet at a 90-degree angle?

Accepted Answer

Perpendicular

Answer

Tangent

Answer

Normal

Answer

Vertical

Question 6

What does a 'Midpoint' constraint do in a CAD sketch?

Accepted Answer

Forces a point to lie at the exact center of a line or arc

Answer

Splits a line into two equal halves

Answer

Makes two lines equal in length

Answer

Centers an element on the origin

Question 7

In most CAD applications, what color are sketch elements typically displayed in when they are 'fully constrained'?

Accepted Answer

Black or dark gray

Answer

Blue

Answer

Red

Answer

Green
