Exercise 5: Hatching and Modify Functions Aim: To draw Figure 5 in AutoCAD 2026. Software: AutoCAD 2026 Commands Used: Limits, Grid Display, Layer, Line (L), Circle (C), Track (TK), Arc, Offset (O), Hatch (H) Procedure: Set limits: Lower (0,0) and Upper (420,297). Set grid display to 2. Create layers for drawing, axes, dimensions, and hatching. Draw a horizontal line of 84 mm using the Line command. From the midpoint of the line, draw a vertical line of 123 mm. Draw circles with diameters/radii ⌀20, R20, ⌀12, ⌀30, and R38 using object snap. Draw the axes for the ⌀12 circle using snap and tracking. Draw a pitch circle with radius 20 mm. At the intersection of the pitch circle and axis, draw circles of radius 7 mm. Draw arcs of radius 13 mm and 27 mm using the ⌀12 circle center. Draw circles of radius 18 mm from the R7 circle centers. Offset the bottom horizontal line by 12 mm. Offset the vertical center line by 25 mm on both sides. Join the endpoints using the Line command. Create fillets with radii R47, R5, and R6. Trim unnecessary lines. Apply hatch to the required area and adjust scale if needed. Add dimensions and annotations. Precautions: Turn ON OSNAP and OTRACK. Turn OFF Grid Snap. Use Ortho mode for vertical and horizontal lines. Keep Dynamic Input ON. Result: Figure 5 is successfully drawn and dimensioned in AutoCAD 2026.
