In this lesson, you create 3D objects by sweeping 2D objects along a path. Loft open and closed 2D objects to create a 3D surface and a 3D solid.10 On the ViewCube, located at the upper-right corner of the drawing window, click Top, Front, Right, and Left to navigate around the hollow cup. 9 At the prompt, enter 10 as the FACETRES value. Variable controls the smoothness of 3D solids. 8 At the Command prompt, enter facetres and press Enter. You have shelled the 3D solid to create a hollow cup. 5 At the prompt, enter X to exit the body editing option.Ħ At the prompt, enter X to exit the solids editing option. Using the create_cup.dwg from the previous lesson, you will hollow the cup by shelling the lofted 3D solid object you created.ġ On the ribbon, click Home tab ➤ Solid Editing panel ➤ Solid Editing drop-down ➤ Shell.ģ Select the top face of the 3D solid and press Enter.Ĥ At the prompt, enter 0.5 as the shell offset distance. When you shell a 3D solid object, new faces are created by offsetting existing faces inside or outside from their original positions. You can shell a 3D solid object using the SOLIDEDIT command. To edit the cup by shelling to create a hollow Ħ At the prompt, enter C for Cross sections only and press Enter.ħ On the ViewCube, located at the upper-right corner of the drawing window, click Top, Front, and Right to navigate around the 3D solid object. On the ribbon, click Home tab ➤ Modeling panel ➤ Solid Creationĥ Select the two largest circles as shown in the drawing and press Enter. In the Select File dialog box, browse to C:/My Documents/Tutorials and To create a cup by lofting 2D closed objects (circles) 1 ġ1 To close the drawing without saving, click NOTE For more information on ViewCube, see the AutoCAD User's Guide or refer to the AutoCAD 2009 tutorial: Navigating a model with ViewCube. ġ 0 On the ViewCube, located at the upper-right corner of the drawing window, click Top and Front to navigate around the sheet. You have created a surface object that represents a sheet. On the ribbon, click Home tab ➤ Modeling panel ➤ Solid Creation drop-down ➤ Loft.ĥ Select the two arcs in the drawing and press Enter.Ħ At the prompt, enter S for Settings and press Enter.ħ In the Loft Settings dialog box, under Surface Control At Cross Sections, select Draft Angles.Ĩ In the Start Angle and End Angle boxes, enter 300 and 280 respectively. In the Select File dialog box, browse to C:\My Documents\Tutorials and select sheet.dwg. To create a surface by lofting a 2D open object (arc) 1 You cannot use a selection set that includes both open and closed objects. The cross sections that you use when lofting must be open to create a surface or all closed to create a solid. Lofting creates a solid or surface object that flows through other objects that define its shape. You can create a 3D solid or surface between cross sections (2D profiles) of the object. Then you modify and edit the lofted 3D object by shelling. In this lesson, you create 3D objects from 2D objects by lofting. Lesson 1: Loft 2D Objects and Shell a 3D Solid In this workspace, you can access the various commands and tools needed for creating 3D drawings. The Workspaces icon in the status bar indicates that you are now in the 3D Modeling workspace. If you still do not see this icon, you may need to maximize the AutoCAD window.Ģ Click the down arrow to display the menu of predefined workspaces. NOTE If you do not see this icon, right-click in an empty area on the status bar and click Workspaces. The workspaces icon on the status bar is shown below. 1 The status bar is located at the bottom of the window.
