Rectangle – Polygon


As we have explored options for drawing an Arc, today we will experiment with a polygon having 4 sides that is a Rectangle. After adding all the openings on the specific layers, your drawing should look like one in the above picture.

Rectangle – Polygon
You can create rectangles and regular polygons quickly. Creating polygons is a simple way to draw equilateral triangles, squares, pentagons, hexagons, and so on.
Two commands, RECTANG and POLYGON, provide an efficient method to create rectangles and regular polygons such as equilateral triangles, squares, pentagons, hexagons, and so on. If necessary, you can use EXPLODE to convert the resulting polyline object into lines.

Draw Rectangles
Use RECTANG to create closed polylines in a rectangular shape. You can specify the length, width, area, and rotation parameters. You can also control the type of corners on the rectangle—fillet, chamfer, or square.

Draw Regular Polygons
Use POLYGON to create closed polylines with between 3 and 1,024 equal-length sides. The following illustrations show polygons created using three methods. In each case, two points are specified.
Exercise – Using Rectangle command, draw a rectangle of size 6” x 3’6” from the midpoint of the lower right corner of the right wall. Make sure that you draw the rectangle on the inner side and it doesn’t overlap or intersect with the wall. Add an Arc from Top-right corner of the rectangle to the midpoint of the opposite wall corner to indicate the swing of the door. Make sure that you draw both these objects on the A-Open-Sec layer. Save your drawing.
