What is the first thing we should set up in SOLIDWORKS when creating a new model?
When starting a new CAD file, the first thing we should do is choose the units we would like to use.
Describe the general parametric modeling procedure.
a. Create a rough two-dimensional sketch
b. Apply/modify constraints and dimensions
c. Extrude, revolve, or sweep the parametric two-dimensional sketch
d. Add additional parametric features by identifying feature relations and complete the design.
e. Perform analyses on the computer model and refine the design as needed.
f. Create the desired drawing views to document the design.
What is the main difference between a rough sketch and a profile?
As the name implies, a rough sketch is not precise at all; while a profile is the completed and precise sketch that is used to create the solid feature.
List two of the geometric constraint symbols used by SOLIDWORKS.
Parallel - indicates a line is parallel to other entities
Perpendicular - indicates a line is perpendicular to other entities
What was the first feature we created in this lesson?
Extruded feature

List and describe three basic Boolean operations commonly used in computer geometric modeling software?
There are three basic Boolean operations: JOIN (Union), CUT (Difference), and INTERSECT.
The JOIN operation combines the two volumes included in the different solids into a single solid.
The CUT operation subtracts the volume of one solid object from the other solid object.
The INTERSECT operation keeps only the volume common to both solid objects.
What is a primitive solid?
a basic three-dimensional shape. The basic primitive solid set typically includes:
Rectangular-prism (Block), Cylinder, Cone, Sphere, and Torus (Tube).
What does CSG stand for?
Constructive Solid Geometry (CSG) method.
CSG describes the solid model as combinations of basic three-dimensional shapes (primitive solids).
Which Boolean operation keeps only the volume common to the two solid objects?
The INTERSECT operation keeps only the volume common to both solid objects.
What is the main difference between an EXTRUDED CUT feature and a HOLE feature in SOLID WORKS?
An EXTRUDED cut feature is a sketched feature, where we created a rough sketch first and performed an extrusion operation.
A hole feature is a placed feature. A placed feature is a feature that does not need a sketch and can be created automatically.
