• Command-line-: Join the divided lines.

• In object, snap setting keep the Extension On.

• Command-line: Draw 2.0m line and 1.5m line and 0.5m horizontal on top and in vertical and 1.5m horizontal and 0.5m vertical and join the slant line.

• Command line:2.0m horizontal and 1.5m vertical on both sides.

• Command offset: offset 1.5m line to 0.5m.

• Command divide: Divide 1.5m line into 3 segments.

• Command-line: Join the divided lines.

Drawing 7:

• New page and set decimal and precision to 0

• Command-line: Drawing 210m horizontal line and 100m vertical line on the left side and 75m vertical line on the right side, since the arc has a radius of 35m drawing a line of 70m on the left side and has a radius of 25m drawing a line of 50m on the right side.

• Command Arc: From the start, end and radius draw an arc of radius 35m on the right side and an arc of radius 25m on the left side.

• Command Circle: From the midpoint of the 70m line on the left side, draw a circle of diameters 50 and 30m on the right side.

• Command offset: Offset 210m line at a distance of 60m.

• Command fillet: Filleting to a radius of 15m on the top right and left and radius of 20m on the inner left and a radius of 6m on the inner right.

• Command offset: Offset 210m line to 10m and 100m and 75m line to 20m.

• Command rectangle:70m length and width of 30m from offset line on both sides.

• Command erase and Trim Command: Erasing the offset line and cutting unwanted lines.

Drawing 8:
