But you can change settings in this dimension style for particular types of dimensions such as the radial type for example. This makes a child dimension style. The child version is based on the parent version but it has a few settings that are different. In this way all your dimensions will be made using the DimPlan dimension style but radial dimensions will use a child version of the style. Once you create a child dimension style from the parent style you refer to both styles by the same name and you call them a dimension style family. Follow these steps to set up a child dimension for radial dimensions 1. Click the Dimension Style button on the Dimension toolbar to open the Dimension Style Manager .
