1 Dimension Styles EDT Chapter 18 - Basic Dimensioning Practices 1

2 Dimension Styles The appearance of dimensions is controlled by over 70 different settings. Dimension Styles are saved configurations of these 70 settings. EDT Chapter 18 - Basic Dimensioning Practices 2

3 Dimension Styles Dimension variables are AutoCAD system variables that help you control the way dimensions look. EDT Chapter 18 - Basic Dimensioning Practices 3

4 Dimension Styles Create a dimension style that has the desired dimension appearance. Name the style appropriately. Dimension styles can have a family of settings that allow you to have different settings for each type of dimension. EDT Chapter 18 - Basic Dimensioning Practices 4

5 Creating Dimension Styles EDT Chapter 18 - Basic Dimensioning Practices 5

6 Creating Dimension Styles To use dimensions most effectively 1. Create a dimension style 2. Use the style to create dimensions 3. AVOID Dimension Overrides. EDT Chapter 18 - Basic Dimensioning Practices 6

7 Creating Dimension Styles You can customize dimension styles to correspond to drafting standards such as: ASME/ANSI ISO MIL Architectural Structural Civil EDT Chapter 18 - Basic Dimensioning Practices 7

8 Creating Dimension Styles Dimension Styles are created using the Dimension Styles dialog box and is selected by: Picking the Dimension Styles button in the Dimension tool bar OR Picking Dimension Style in the Format pulldown menu OR Entering D or DDIM at the Command: prompt EDT Chapter 18 - Basic Dimensioning Practices 8

86 Overriding Dimensioning Variables EDT Chapter 18 - Basic Dimensioning Practices 86

87 Overriding Existing Dimensioning Variables You can alter dimensioning variables to modify one or more specify dimensions on the drawing. Command: DOV or DIMOVERRIDE Dimension variable to override or Clear to remove overrides): DIMEXO Current Value <0.062> New value: 0 Dimension variable to override: (type another variable name to override or press [Enter]) Select objects: EDT Chapter 18 - Basic Dimensioning Practices 87

88 Overriding Existing Dimensioning Variables The variable changes on as many dimensions as you pick. You can also clear any previous overrides by using the Clear option. EDT Chapter 18 - Basic Dimensioning Practices 88

89 Dimensioning Variables AutoCAD uses variables to modify the appearance of dimensions. AutoCAD has 72 (!) variables associated with dimensions. EDT Chapter 18 - Basic Dimensioning Practices 89

90 Dimensioning Variables By using dimension styles, you can pre-set many of these variables. Use different dimension styles to create different types of dimensions. EDT Chapter 18 - Basic Dimensioning Practices 90
