Dimension styles affect the appearance of dimensions and can be used to create a consistent standard for dimensioning techniques.
Two options when creating a new dimension style is to use it for all dimension types or to limit it to a particular type of dimension. This example will explain how to create a new dimension style to be used only for linear dimensions.
AutoCAD r13 and r14 introduced the concept of using a dimension style for selected types of dimensions. The group of dimension styles used in this fashion was called a Dimension Style Family. The dimension style used for any type of dimension unless otherwise specified was called the parent dimension style.
One of the changes in AutoCAD 2000 is that the family members are more closely related. Unless a setting has been specified by a family member, the base (parent) dimension style parameters are used. This creates an on-going relationship with the base dimension style and those created from it. Dimensions created using our new dimension style will appear as shown at the right.
All dimension text will be horizontal, with the exception of linear dimensions. The dimension text in linear dimensions will be aligned with the dimension line and be placed above the it. Additionally, all dimensions will use arrowheads, except linear dimensions.
