Dimensioning Concepts

Dimensions show the measurements of objects, the distances or angles between objects, or the X and Y values of the coordinate of a point on a feature. AutoCAD LT provides three basic types of dimensioning: linear, radial, and angular. Dimensions can be horizontal, vertical, aligned, rotated, ordinate, baseline, or continued. A simple example of each is shown in the illustrations.

You can dimension objects, such as lines, arcs, circles, and polyline segments, or you can dimension between point locations.

AutoCAD LT places dimensions on the current layer. Every dimension assumes the current dimension style, which controls characteristics such as color, text style, and linetype scale. With dimension style families (groups of dimension styles), you can make subtle modifications to a base dimension style for different types of dimensions. With dimension style overrides, you can modify these characteristics for a specific dimension.
