• Take offset of 2 units line at 0.5 distance from both the side and trim the remaining portion as per required drawing.
• Draw the line lengths 1.5 units in +ve Y direction and 2 units in -ve x direction.
• Take offset from 1.5 units of 0.5 distance then connect it with 2 units line.
• Take offset from 2 units line at 0.5 distance from both the side and trim the remaining portion as per required drawing.
• Using line command draw L shape geometry of size 0.5 and 1.5 units and connect to make the triangular portion.
• Annotate and give dimensios to all line segments and Circles.

• Draw the line lengths 210 units in +ve X direction and line of @100<270 and @75<270 units.
• Draw the Rectangle form 10 units distance sizes 70X30 and copy the object at 30 units distance.
• Draw the arc of radius 35 units at 100 unit line.
• From that center draw circle of raduis 25 units.
• Draw the arc of radius 25 units at 75 unit line.
• From that center draw circle of raduis 15 units.
• Draw the line of 40 units from arc 1 and 90 units in +Ve X direction.
• Select the chamfer tool by entering CHA Command in tab.
• Draw the chamfer sizes 20, 15,20 and 6 in the Drawing.
• Annotate and give dimensios to all line segments and Circles.
