Creating Horizontal and Vertical Dimensions

To create a horizontal or vertical dimension

1. From the Dimension menu, choose Linear.
2. Press ENTER to select the object to dimension, or specify the first and second extension line origins.
3. Before specifying the dimension line location, you can override the dimension direction and edit the text, the text angle, or the dimension line angle:
   
   • To rotate the extension lines, enter r (Rotated). Then enter the dimension line angle.
   • To edit the text, enter mtext. In the Multiline Text Editor dialog box, revise the text and choose OK. Editing within or overwriting the brackets (<>) will change or remove the dimension value calculated by AutoCAD LT. Adding text before or after the brackets will append text before or after the dimension value.
   • To rotate the text, enter a (Angle). Then enter the text angle.
4. Specify the dimension line location to complete the dimension.
