AUTOCAD 2008 PREVIEW GUIDE 

 

Figure 57. Inspection Dimension dialog box. 

You can add a jog to linear dimensions to represent measurements whose values are not the same length as 

the dimension line. Jogged dimension lines are typically used when a sheet is too small to display the true 

length of a dimension line. Using the Dimension Jog tool (DIMJOGLINE command), you can select the 

dimension and indicate where you want to place the jog. You can edit the jog location using grips and you can 

turn off the jog or edit its height using the Properties window. Additionally, a new option for linear jog size is 

included on the Symbols and Arrows tab of the Dimension Style dialog box. 

 

Figure 58. Jogged Linear Dimensions 

The new Dimension Space tool (DIMSPACE command) enables you to evenly space selected dimensions. You 

can specify the spacing distance between dimension lines or let AutoCAD automatically determine a minimum 

spacing distance.
