The tools in this tutorial will help you accomplish that task.Exe

3、rcise: Creating and Editing Line DataThis exercise teaches you how to create lines and surfaces.Step 1: Create a component collector to geometry.1.Access the components sub-panel in one of the following ways:From the toolbar, click components (). From the Menu Bar, select Collectors, then Create and

4、 click Components.2.For comp name = type geometry.3.Use the switch () to toggle from card image = to no card image.4.Click color and chose yellow.5.Click create.6.Click return.Step 2: Create nodes.1.On the standard toolbar, click Isometric View, ().2.Access the create nodes panel in one of the follo

5、wing ways:From the Menu Bar, select Geometry, then Create, and then click Nodes.From the main menu, access the Geom page and click nodes3.Go to the type in sub-panel.4.Create five nodes by entering the X, Y, and Z coordinates from the following table and click create node for each of the nodes.NodeX
