Nếu bạn kích đúp vào một đối tượng văn bản multiline, Multiline Text Editor được hiển thị trong các băng cùng với Text Editor In-Place. Nếu bạn kích đúp vào dòng văn bản duy nhất một đối tượng, In-Place Text Editor mở ra, nơi bạn có thể chỉnh sửa văn bản trong cùng một cách mà bạn tạo ra nó. | Dimensions for Linear Objects Guidelines Always use Object Snaps to select the dimension origin points. Depending on the geometry you are dimensioning you may select objects to dimension rather than specifying the endpoints. A Linear dimension will be horizontal or vertical depending on the direction you drag the dimension line from the object. An Angular dimension may be located inside or outside the angle depending on where you drag the arc line location. To ensure that Continuous and Baseline dimensions build correctly create the base Linear Aligned or Angular dimension choosing the first and second origin points accordingly. Baseline dimensions are built from the first origin point. Continuous dimensions are built from the second origin point. When you select the base dimension for your Continuous or Baseline dimensions select the dimension towards the side that you want the continued or baseline dimension to reference. Adjust the location of the dimension using Grips when necessary. If the origin point you selected is incorrect zoom in closer to the object and use the grips to relocate the origin point to the object. The Dimlinear and Dimaligned commands prompt you for two points or to select an object. Press ENTER to select the object to dimension. This is often quicker than selecting two points. 104 Chapter 8 Dimensioning Creating Dimensions on Curved Objects Using commands to place dimensions on curved objects in the drawing is a straightforward process. Pay attention to the command prompts as they guide you through the required selections. These dimensions can be selected from the list on the Dimensions panel. The following illustration shows a variety of dimensions for curved objects.
