The Rectangle command enables you to create a rectangle. You can choose two different methods in the Mode drop-down list:
2 Vertices
specify two opposite vertices (corners) or the first vertex and the X size and Y size (enter each value into the corresponding box, press TAB to confirm and move to the other box. Press ENTER to create the rectangle.)
Cen+Sizes
specify its center, X size and Y size
and its orientation Angle (measured counterclockwise starting from the X-axis).
When working in the model (three-dimensional) environment, the resulting entities are created on the Work Plane.
