When creating a sketch, what must connect to it to make it Fully- Defined?

• An Axis

• A Vertex

• The Origin

• A Plane/Planar Face

Answer explanation

When making a sketch in SolidWorks, the origin has to have some relation to the drawing, either directly or indirectly.

Which of these are relations or constraints in SolidWorks?

• Tangent

• Perpendicular

• Coincident

• Fillet

• Vertex

Answer explanation

Relations or Constraints are the rules that are applied to a sketch to show the relationship between the lines and curves. The most common ones are: Coincident, Parallel, Perpendicular, Tangent, Horizontal, Vertical, Collinear, and Concentric.

Where can you create your sketches on?

• Planar Face

• Front and Right Planes

• Top plane

• Radius

Answer explanation

The Front, Top, and Right planes are the default surfaces around the origin and can be used to sketch a part. The planar face is any of the flat faces on a part that can be used to sketch more or less material.

What is the difference between an Axis and a Vertex?

• There is no difference

• A Vertex is a line used for defining the shape and features of a part; An Axis is a point used for defining the shape and features of a part

• An Axis is a line used for defining the shape and features of a part; A Vertex is a point used for defining the shape and features of a part

Answer explanation

The dotted line shown is one of the Axis' of the part and is used for dimensioning and constraining the sketches and features of the part. The two blue dots are some of the vertexes of the part and they have a similar role like the Axis.

What will happen if the sketch is not attached to the origin and you move it?

• The part will stay in place

• Some sides of the part will move while others will stay in place

• The sketch will never be fully defined

• The part will fully move

Answer explanation

Whether it is meant to be arbitrary or not, if the origin is not attached to the sketch either directly or indirectly, the sketch will move freely and will never be fully defined.

What is the color of the lines when a sketch is undefined?

Answer explanation

In SolidWorks, when a sketch has blue lines, the sketch is underdefined and can be moved; Make sure you have all the dimensions and that all needed relations and constraints are present.

What is the color of the sketch when it is Fully Defined

Answer explanation

When a sketch is fully defined in SolidWorks, the entire part should be black and there is no more movement. That does not mean that it is right, so make sure your dimensions are correct.

When putting a dimension on a circle, what are the two options that can appear?

• Radius

• Diameter

• Inches

• Millimeters

Answer explanation

When making a circle, arc, or any circular design in SolidWorks, placing a dimension on it will give you the option of either a Radius or a Diameter. Make sure you know their symbols and how to calculate between them.

What are the two units you will be using throughout this course?

• (IPS) Inches, Pounds, Seconds

• (CGS) Centimeters, Grams, Seconds

• (MMGS) Millimeters, Grams, Seconds

• (MKS) Meters, Kilograms, Seconds

Answer explanation

Before starting you part, always verify that your units in SolidWorks are the same in the drawing. This course only uses IPS and MMGS.

When smoothing or flattening out the edges in your part, what are the options?

• Fillets

• Chamfers

• Offset

• Isometric

Answer explanation

Some parts will have chiseled or Rounded edges, these are Fillets and Chamfers in action. You can create them in the sketch or as an additional feature.
