1) 3 point: Specify three points through which the arc passes
University of Technology Computer engineering and information technology Department 1) 3 point: Specify three points through which the arc passes The Arc command prompt is: Command: arc Specify start point of arc or [Center]: 10, 10 Specify second point of arc or [Center/End]: 20, 10 Specify end point of arc: 10, 20
4
Specify start point of arc or [Center]: 10,10
University of Technology Computer engineering and information technology Department 2) Start, Center, End: The radius is defined by the first two points that you specify. Command: arc Specify start point of arc or [Center]: 10,10 Specify second point of arc or [Center/End]: c Specify center point of arc: 20,20 Specify end point of arc or [Angle/chord Length]: 10,20

University of Technology
Computer engineering and information technology Department Rectangle: The rectangle command only requires the specification of two diagonal corners for construction of a rectangle. Command: Rectangle Specify first corner point or[chamfer/ elevation/ fillect/thicknss/width] :x,y Specify other corner point: x,y 8
9
A rectangle can have width:
University of Technology Computer engineering and information technology Department A rectangle can have width: Specify first corner point or [chamfer/fillet/width]: W Specify line width for a rectangle <0.0000>: 10 Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: 10,10 Specify other corner point or [Dimensions]: 40,40 9
10
Specify fillet radius for rectangles <0.0000>: 10
University of Technology Computer engineering and information technology Department The fillet option allows you to specify values for the fillet radius at four rectangular corners: Command: rec Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: F Specify fillet radius for rectangles <0.0000>: 10 Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]:10,10 Specify other corner point or [Dimensions]: 40,40 10
