Geometric Constraints

TRUE OR FALSE
The Concentric constraint forces two circles, arcs, or ellipses to share a common center point.

• True
• False

Limits or restrictions that are placed on geometry to define a model’s shape and size are ____________.

• geometric entities
• constraints
• sketch planes
• regions

The constraint that forces two selected lines or curves to lie at right angles to one another is ___________.

• parallel
• vertical
• perpendicular
• coincident

The constraint that indicates a set of curves or lines are touching without overlapping.

• equal
• smooth
• tangent
• symmetric

The constraint that forces two points to be constrained together, or causes one point to lie on a curve.

• coincident

• colinear

• concentric

• parallel

The constraint that forces lines drawn at the same length or that arc or circle drawn have the same radius.

• horizontal

• equal

• vertical

• parallel

Symbols that show alignments, perpendicularities, tangencies, and other relationships are known as __________ symbols. 

• geometric constraint
• drafting
• function
• engineering drawing

The __________ constraint causes the lines or axes drawn to be parallel to the y-axis.

• horizontal

• vertical

• parallel

• datum

What is the definition of a "constraint" in inventor?

• Restrictions and associations that are applied to 2D geometry (shapes, points, lines) to make them line up or connect in a certain way

• The limits and restrictions a designer must consider at the beginning of a project

• Devices that keep a person from moving

• Specifications for the size of a design, 2D or 3D

Which constraint symbol matches coincident: occurring together in space or time. For example, the ends of the lines were coincident - they were on top of each other.
