Select 3D Modeling from the list. The Ribbon will now change to the 3D Modeling Workspace.
3. Select the Box drop-down arrow on the Modeling Panel of the Home Tab.
4. Select a 3D Tool from the list. For example, Sphere.
Method 3 – Draw pull-down Menu on the Menu Bar.
The Menu Bar is hidden by default on all Workspaces in AutoCAD. To enable the Menu Bar do the following.
1. Select the drop-down arrow on the Quick Access Toolbar.
2. Select Show Menu Bar from the list. The Menu Bar will now appear across the top of the Workspace Ribbon.
3. Select the Draw pull-down Menu.
4. Select Modeling from the list.
5. Select a 3D Tool from the list. For example, Pyramid.
Method 4 – Keyboard entry.
Method 4 is probably the easiest way to initiate a 3D Modeling command if you prefer to use keyboard entry. You can use keyboard entry for all commands within AutoCAD. To initiate a 3D modeling command using keyboard entry do the following.
1. On the Command Line or in the Dynamic Input Box, type in the name of the 3D Modeling tool you require. For example, wedge. (Lowercase is OK.)
2. Press <enter> on your keyboard.
Note: The Dynamic Input Box will appear when you start to type in the main drawing area. Make sure Dynamic Input is turned ON for this lesson. Pressing F12 on your keyboard toggles Dynamic Input on or off.
There are several methods you can use to create a Solid Box. The information you have for the size and position of the Box will determine the method you use to create it.
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 a start position, diagonal corner position and height of the Box.
1. Start a new drawing file by selecting either acad.dwt for inch users, or acadiso.dwt for metric users. (Refer to page Intro-2.)
2. Select the SE Isometric view. (Refer to page Intro-7.)
3. Select the Box tool. (Refer to pages 1-2 through 1-5.)
4. Specify first corner or [Center]: 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. Move your mouse down and to the right. (For X+ and Y+ positions.)
6. Specify other corner or [Cube/Length]: type in 6,4 [152.4,101.6] then press <enter> (P2).
7. Move your mouse up. (For Z+ position.)
8. Specify height or [2Point]: type in 3 [76.2] then press <enter> (P3).
A solid Box has been created with a length (X+ Axis) of 6” [152.4 mm], a width (Y+ Axis) of 4” [101.6 mm], and a height (Z+ Axis) of 3” [76.2 mm]. And with a start position of X0, Y0, Z0.
Note: The solid Box is displayed in Conceptual style. (Refer to page Intro-9.)
Method 2 – Using a start position, length, width and height of the Box.
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 Box tool.
4. Specify first corner or [Center]: 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. Move your mouse up and to the left. (For X– and Y– positions.)
6. Specify other corner or [Cube/Length]: type in L then press <enter>.
Note: When using the Length method, make sure Ortho Mode is turned on by pressing F8 on your keyboard or by selecting the Ortho icon on the Status Bar. This constrains the cursor to just horizontal and vertical movements. (Refer to page Intro-11.)
7. Specify length: type in 5.25 [133.35] then press <enter>.
8. Specify width: type in 3.2 [81.28] then press <enter>.
9. Move your mouse down. (For Z– position.)
10. Specify height or [2Point]: type in 2.5 [63.5] then press <enter>.
A solid Box has been created with a length (X– Axis) of 5.25” [133.35 mm], a width (Y– Axis) of 3.2” [81.28 mm], and a height (Z– Axis) of 2.5” [63.5 mm]. And with a start position of X0, Y0, Z0.
Method 3 – Using a start position, with the length, width and height of the Box all having the same dimensions.
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 Box tool.
4. Specify first corner or [Center]: 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. Move your mouse up and to the right. (For X– , Y+ and Z+ positions.)
6. Specify other corner or [Cube/Length]: type in C then press <enter>.
7. Specify length: type in 5 [127] then press <enter>.
