Drawings are made up of objects. In general, you draw objects by specifying points with the pointing device or by entering coordinate values at the command prompt.
You can create a range of objects, from simple lines and circles to spline curves, and ellipses. In general, you draw objects by specifying points with the pointing device or by entering coordinate values at the command prompt.
A line, the most basic object, can be one segment or a series of connected segments.
Curved objects are arcs, circles, polyline arcs, donuts, ellipses, and splines.
Construction lines and reference points are temporary objects you create to help you draw accurately.
Regions are two-dimensional enclosed areas that have physical properties such as centroids or centers of mass. You can combine existing regions into a single, complex region to calculate area.
Revision clouds are polylines that consist of sequential arcs. They are used to call attention to parts of a drawing during the review stage.
