4.12-4.14 CONE

What is a three-dimensional cone?

• A three-dimensional cone is a geometric shape that has a square base and a flat top, with straight sides connecting the base and the top.

• A three-dimensional cone is a geometric shape that has a triangular base and a rounded top, with straight sides connecting the base and the top.

• A three-dimensional cone is a geometric shape that has a rectangular base and a pointed top, with curved sides connecting the base and the top.

• A three-dimensional cone is a geometric shape that has a circular base and a pointed top, with curved sides connecting the base and the top.

• Designing aerodynamically efficient nose shape.

• Developing designs for edible ice cream holders.

• Design to ensuring optimal audio quality.

• Designing conical traffic cones used for guidance and information.

Match the following case studies with their correct descriptions:

Groups:

(a) The Gherkin:

,

(b) The Vessell

,

(c) Ice Cream Cone

• A public artwork in Hudson Yards, Manhattan.

• It is difficult to say who invented it, but it has been popular for over a hundred years

• A unique & innovative design in London's skyline.

Match the following terms with their definitions:

​ (a)     - The distance between the center point and quadrant 

​ (b)   - The elevated distance on the Z-Axis from the base point to the vertex

​ (c)   - The distance from the base quadrant to the Apex

• SLANT HEIGHT
• HEIGHT
• Radius
• Diameter

To access the 'cone' command using the shortcut, type the following and then press enter: "____".

Reorder the following steps to create a cone with a specified radius tangent to two objects:

• Type 'CONE' or press the 'CONE' command

• Specify the height the cone

• Specify the radius of the cone

  
  

• Starts the cone by setting the base point of the bottom of the cone.

Match the following modifiers with their functions:

• Three Points (3P)

• Defines the base circumference and base plane of the cone by specifying three points.

• Elliptical (E)

• Specifies an elliptical base for the cone.

• Tan-Tan-Radius (TTR)

• Defines the base diameter of the cone by specifying two points.

• Two Point (2P)

• Defines the base of the cone with a specified radius tangent to two objects.

• Top Radius (T)

• Specifies the top radius of the cone, creating a cone frustum

Match these misconceptions with their corrections:

• Can I use the diameter?

• Absolutely, modifiers like 3-point, 2-point, or tan-tan radius offer such versatility.

• Can I form a cone without a center point

• Absolutely! Use the diameter modifier when creating a cone.

• Can I position the cone's tip under it?

• Yes, apply the ellipse modifier for an elliptical cone.

• Can I shape cones like ellipses?

• Yes, simply move your mouse below the base or input a negative value.
