In the Dimension Style Manager (DDIM command), users must navigate through multiple tabs and menus to modify the size of the dimensions. One major advantage of using DIMSTYLE over the Dimension Style Manager is speed. With DIMSTYLE, users can change the CAD scale factor of their dimension text height, arrowhead style, and extension line length, all using one setting. DIMSTYLE is a command in AutoCAD that allows users to quickly and efficiently modify the properties of dimensions in a drawing.
