a radius and height.
1. Start a new drawing file by selecting either acad.dwt for inch users, or acadiso.dwt for metric users.
2. Select the SE Isometric view.
3. Select the Cone tool.
4. Specify center point of base or [3P/2P/Ttr/Elliptical]: type in 0,0,0 on your keyboard then press <enter> (P1). (You can also place the cursor in any position and then left click with your mouse.)
5. Specify base radius or [Diameter]: type in 1.125 [28.57] then press <enter>.
6. Move your mouse up. (For Z+ position.)
7. Specify height or [2Point/Axis endpoint/Top radius]: type in 2.75 [69.85] then press <enter> (P2).
A solid Cone has been created with a radius of 1.125” [28.57 mm], and a height of 2.75” [69.85 mm]. And with a start position of X0, Y0, Z0 at the base center of the Cone.
Note: The base of the Cone is located on the “X, Y” plane and with the height of the Cone in the “Z” axis. (You can also create a Cone using the axis endpoint. Refer to page 1-12.)
Method 2 – Using the base center position of the Cone, a base radius, a top radius and height.
1. Start a new drawing file by selecting either acad.dwt for inch users, or acadiso.dwt for metric users.
2. Select the SE Isometric view.
3. Select the Cone tool.
4. Specify center point of base or [3P/2P/Ttr/Elliptical]: type in 0,0,0 on your keyboard then press <enter> (P1). (You can also place the cursor in any position and then left click with your mouse.)
5. Specify base radius or [Diameter]: type in 1.5 [38.1] then press <enter>.
6. Specify height or [2Point/Axis endpoint/Top radius]: type in T then press <enter>.
7. Specify top radius: type in .5 [12.7] then press <enter>.
8. Move your mouse up. (For Z+ position.)
9. Specify height or [2Point/Axis endpoint]: type in 2.5 [63.5] then press <enter> (P2).
A solid Cone has been created with a base radius of 1.5” [38.1 mm], a top radius of 0.5” [12.7 mm], and a height of 2.5” [63.5 mm]. And with a start position of X0, Y0, Z0 at the base center of the Cone.
Note: The base of the Cone is located on the “X, Y” plane and with the height of the Cone in the “Z” axis. (You can also create a Cone using the axis endpoint. Refer to page 1-12.)
A Solid Sphere can be created by specifying the center point location and a radius or diameter for the size.
Note: The sizes shown in brackets [...] are for metric users. Enter the numbers without the brackets. For example, [12.7] just enter 12.7
Method 1 – Using the center position of the Sphere and radius.
1. Start a new drawing file by selecting either acad.dwt for inch users, or acadiso.dwt for metric users.
2. Select the SE Isometric view.
3. Select the Sphere tool.
4. Specify center point or [3P/2P/Ttr]: type in 0,0,0 on your keyboard then press <enter> (P1). (You can also place the cursor in any position and then left click with your mouse.)
5. Specify radius or [Diameter]: type in 1.575 [40] then press <enter>.
Note: If you want to enter the diameter of the Sphere type in D then press <enter>, then type in the diameter and press <enter> again.
A solid Sphere has been created with a radius of 1.575” [40 mm]. And with a start position of X0, Y0, Z0 at the center of the Sphere.
There are various methods you can use to create a Solid Pyramid. You can create a Pyramid that has the base circumscribed around a radius, or you can have the base inscribed within a radius. You can also have the Pyramid as an apex (sharp point), or a truncated Pyramid, which has a flat top parallel to the base. You can choose to have between 3 and 32 sides for the pyramid.
Note: The sizes shown in brackets [...] are for metric users. Enter the numbers without the brackets. For example, [12.7] just enter 12.7
Method 1 – Using the center position of the Pyramid with the base circumscribed around a radius.
1. Start a new drawing file by selecting either acad.dwt for inch users, or acadiso.dwt for metric users.
2. Select the SE Isometric view.
3. Select the Pyramid tool.
4. Specify center point of base or [Edge/Sides]: type in S on your keyboard then press <enter>.
5. Enter number of sides [4]: type in 6 then press <enter>.
6. Specify center point of base or [Edge/Sides]: type in 0,0,0 then press <enter> (P1).
7. Specify base radius or [Inscribed]: type in 1.4 [35.56] then press <enter>.
8. Move your mouse up. (For Z+ position.)
9. Specify height or [2Point/Axis endpoint/Top radius]: type in 4 [101.6] then press <enter> (P2).
A solid Pyramid with 6 sides has been created with the base circumscribed around a radius of 1.4” [35.56 mm], and a height of 4” [101.6 mm]. And with a start position of X0, Y0, Z0 at the center of the Pyramid.
Method 2 – Using the center position of the Pyramid with the base inscribed within a radius.
1. Start a new drawing file by selecting either acad.dwt for inch users, or acadiso.dwt for metric users.
2. Select the SE Isometric view.
3. Select the Pyramid tool.
