Step 2 To start, click the Symbols panel and drag the patterned strip into it. In the dialog box that pops up, name the new symbol ‘Pattern Strip’ and indicate its type by clicking the ‘Graphic’ button. Now hit OK to add it to the Symbols library.
Step 3 The large orange circle will form the object’s base. Click on it, go to the menu bar and select Effect > 3D > Extrude & Bevel.
Step 4 In the 3D Extrude & Bevel options, select Isometric Top in the Position drop-down menu. Set the Extrude Depth to 38 pt and select No Shading from the Surface drop-down. To see 3D magic take place on the artboard before you’ve even dismissed the dialog box, make sure that the Preview box on the right is ticked.
