Use the following methods to create 2D lines, polylines, curves and closed polygons on the Floor Plan or in the 3D Window.
The result, however, is a Morph face or a Morph line, rather than a 2D polygon or line: it is displayed in the 3D window, but has no geometric parameters (e.g. thickness). You can use the resulting 3D lines and surfaces for sketching or documenting purposes in the 3D window.
The Free-Rotate Rectangle input method of the Morph tool allows you to draw the rectangle on any plane in space.
