# CADD-2 Lesson 7

### Solid Modeling

Command/OperationDefinition
Primitive Basic building block of solid models.
Solid Modeling Computer modeling of 3-Dimensional volumes of solid parts.
Cylinder Creates a solid cylindrical primitive
Torus Creates donut shaped solid primitives.
Cone Circular solid primitive that meets at a point.
Wedge Creates a solid wedge.
Box Creates a solid box.
Sphere Creates a solid sphere primitive such as a ball bearing.
Pyramid Creates a solid pyramid primitive.
Revolve Turns a polyline about an axis to create a 3D Model.
Extrude Allows you to add depth to a closed volume.
MASSPROP Calculates the mass-volume of a 3D solid model.
Sweep Moves a 2D profile along a path or curve.
Helix Open 3D Spiral.
Loft Creates a new solid model or surface by specifying a series of 2 D cross sections.
Thicken Allows you to create a solid from a surface.
Boolean Logic System for use with logic formulas and operations in 3D.
Boolean Operations Such as Union, Subtract, and Intersect, are used to create composite solids.
Composite Solids are composed of two or more solid objects.
Subtract A boolean operation that removes one solid object from another.
Union A boolean operation that allows you to join to solids to form a new composite solid.
Subobject A face, edge, or corner of a solid model. Many tools used to modify 2D objects may also be used in 3D.
3DMove Allows you to move objects in 3D space.
3DRotate Allows you tom rotate objects in 3d Space.
PRESSPULL Allows you to press or pull any closed 2D profile on the face of a solid. Press is a combination of the extrude & subtract commands. Pull is a combination of the extrude & union commands.
Visual Styles Allows you to view a model as a wireframe, conceptual, or realistic views.
Paper Space Layout views similar to actual paper
Model Space Actual area we normally create drawings
Viewports Allows you to view different parts of a drawing while in Paper Space.
Shell Converts a 3D solid into a hollow shell with a wall of wanted thickness.
Slice Removes a portion of a solid by creating a cutting plane.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
