  1. Exercise • To Draw the Triangle • Command: LINE • Specify first point: (pick a point in the middle of the drawing area) • Specify next point or [Undo]: @15,0 • Specify next point or [Undo]: FROM • Base point: MID • of (pick a point near the middle of the line) • <Offset>: @0,75 • Specify next point or [Undo]: C (to close) • To Draw the Vertical Line • Command: LINE • Specify first point: MID • of (pick point near the middle of the triangle base) • Specify next point or [Undo]: @0,-100 • Specify next point or [Undo]: • To Draw the Horizontal Line • Command: LINE • Specify first point: FROM • Base point: MID • of (pick a point near the middle of the vertical line) • <Offset>: @-25,0 • Specify next point or [Undo]: @50,0 • Specify next point or [Undo]:

  2. Exercise • To Draw the Circle • Command: CIRCLE • Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: INT • of (pick a point near the intersection of the two lines) • Specify radius of circle or [Diameter]: 12.5 • To Trim the Lines within the Circle • Command: TRIM • Current settings: Projection=UCS Edge=None • Select cutting edges ... • Select objects: (pick the circle on its circumference) • Select objects: • Select object to trim or [Project/Edge/Undo]: (pick one of the lines within the circle) • Select object to trim or [Project/Edge/Undo]: (pick the other line within the circle) • Select object to trim or [Project/Edge/Undo]:

  3. Exercise • To Draw the Text • Command: DTEXT • Current text style: "Standard" Text height: 2.5000 • Specify start point of text or [Justify/Style]: J • Enter an option [Align/Fit/Center/Middle/Right/TL/TC/TR/ML/MC/MR/BL/BC/BR]: M • Specify middle point of text: CEN • of (pick a point on the circumference of the circle) • Specify height <2.5000>: 15 • Specify rotation angle of text <0>: 0 • Enter text: N • Enter text: • Command:

  4. Exercise • Draw a square 1*1. (1,2,3,4) • Draw an arc AB, centered at 1, radius=1 units. • Continue drawing arcs BC, CD, DE…etc, with radii 2 units, 3 units, 4 units …etc. respectively.

  5. Exercise • Draw a equilateral triangle in a circle with a radius of 50 units. • Follow the instructions; • Draw circle ABCD, with radius of 50 units. • Draw another circle with a radius of 50 units, centered at A. Use “Quadrant” osnap function. • Join the intersecting points C and D (use “Intersection” osnap function) with point B (Use “Quadrant” osnap function)

  6. Exercise • Draw a equilateral hexagon in a circle with a radius of 50 units. • Follow the instructions; • Draw a circle, with radius of 50 units. • Draw another circle with a radius of 50 units, centered at A. Use “Quadrant” osnap function. • Join the intersecting points B and C (use “Intersection” osnap function) with point A. (Use “Center” osnap function). • Use “Mirror” command, copy BA and AC with respect to the vertical axis (Use “Quadrant” osnap function for the mirror reference).

  7. Homework • Use different layers for actual drawing and the construction lines. • No need to write the dimensions. • Use “CENTER2” for construction line types.
