mxdt0002-Creating the model of the chair using the lofting technique

In this section, you will use the lofting technique to create the model of the chair in 3ds Max Design. You will loft two shapes, star and circle along a path to get the desired shape as shown in Figure 1.

Figure 1  The model of the chair

Before starting the work, you need to change the unit settings in 3ds Max Design. To do so, start Autodesk 3ds Max Design; a default interface is displayed. Choose Customize > Units Setup from the menu bar; the Units Setup dialog box is displayed, as shown in Figure 2. Select the US Standards radio button and Inches radio button under the Display Unit Scale region. Now, choose the OK button to close this dialog box.

maxdt0001-Working in a new Customizing Viewport Layout

This feature will guide you how to customize viewport layouts in Autodesk 3ds Max Design. You can use this technique to customize your workspace as per your requirements. This is very great technique to segregate your work in different workspaces to reduce time and extra effort. In other words, you can easily switch between a number of viewports. You can use the viewport layout bar to manage your viewport layout settings. This bar is opened by default along with Autodesk 3ds Max Design interface.

To learn how to use this customization technique, follow the steps given below:

• Start Autodesk 3ds Max Design; the default interface is displayed along with the viewport layout bar, as shown in Figure 1.

                                             Figure 1  The default interface displayed

• Choose the Create a New Viewport Layout Tab icon from the viewport layout bar; the list of different in-built layouts is displayed in the Standard Viewport Layouts window, as shown in  Figure 2.

Figure 2  The list of in-built layouts displayed

• Choose any one tab from the list of Standard Viewport Layouts window; the new workspace is displayed, as shown in Figure 3. Note that the new tab is also added in the viewport layout bar.

  Figure 3  The new workspace displayed

• To rename this workspace, righ-click on the newly added tab; a flyout is displayed. In this flyout, enter the name as Workspace 1 in the Name text box, as shown in Figure 4. Press the ENTER key to confirm the changes. You can also delete this tab by clicking on the Delete Tab, refer to Figure 4.

Figure 4  Renaming the workspace

          Next, you will start working on this newly created workspace.

• Choose Create > Geometry in the Command Panel. Make sure the Standard Primitive options is selected in the drop-down list, as shown in Figure 5.

                              Figure 5  The Command Panel

• Invoke the Sphere tool from the Object Type rollout and create a sphere in any viewport, as shown in Figure 6.

Figure 6  Creating a sphere

• Activate the Front viewport. Select the sphere by invoking the Select and Move tool. Hold the SHIFT key and drag the sphere to the right. Now, release the mouse and the SHIFT key; the Clone Options dialog box is displayed. Select the Copy radio button and enter 5 in the Number of Copies spinner, as shown in Figure 7. Choose the OK button; the five copies of sphere are created, as shown in Figure 8.

Figure 7  The Clone Options dialog box

Figure 8  Five copies of sphere created

• Invoke the Select and Move, Select and Rotate, and Select and Uniform Scale tools from the Main Toolbar. Next, modify the shape of the spheres and align them in all viewports, as shown in Figure 9.

Figure 9  Modifying and aligning the spheres

• Choose Group > Group from the menu bar; the Group dialog box is displayed. Enter the name Sphere01 in the Group name text box to group these spheres, as shown in Figure 10. 

Figure 10  The Group dialog box

         Next, you will create another sphere in the Perspective viewport and animate it in such a way so that it  
         will revolve round the Sphere01. 

• Activate the Perspective viewport and create another sphere and scale down its size by using the Select and Scale tool.
• Choose the Toggle Auto Key Mode button in the time controls to enter the animation mode, as shown in Figure 11.

Figure 11  The time controls

• Enter 25 in the current frame spinner and press the ENTER key.
• Invoke the Select and Move tool from the Main Toolbar and Selection Lock Toggle button on the status bar.
• Activate the Top viewport and change the view from Wireframe to Shaded.
• Select the sphere in the Top viewport and drag it in such a way so that it appears above the Shpere01 in the viewport, as shown in Figure 12.

• Enter 50 in the current frame spinner and press the ENTER key to move the next frame.
• Move the sphere to the left of the Sphere01, as shown in Figure 13.

Figure 13  Aligning sphere on the left of Sphere01

• Enter 75 in the current frame spinner and press the ENTER key to move to next frame. Alternatively, you can directly drag the Time Slider to frame 75.
• Similarly, move the sphere below the Sphere01
• Enter 100 in the current frame spinner and press the ENTER key.
• Move sphere back to its original position, as shown in Figure 14.

• Choose the Toggle Auto Key Mode button to exit the animation mode.
• Make sure the Perspective viewport is active and then choose the Play ANimation button to play the animation. The sphere will rotate around the Sphere01, as shown in Figure 15.
