CADM LAB | EXERCISE - 3 | TUTORIALS | BASIC DIAGRAMS

Aim: To draft Figure 3 using AutoCAD 2026. Software Used: AutoCAD 2026 Commands Used: LIMITS, GRID, RECTANGLE (REC), CIRCLE (C), POLYGON (POL), LAYER, LTSCALE, FILLET (F), ARRAY (AR) Procedure: Set the drawing limits. Lower limit: (0,0) Upper limit: (420,297) Set the grid display spacing to 2. Draw a rectangle of dimensions 70 mm × 40 mm. First point: (0,0) Enter @70,40 Draw a circle of 17 mm diameter at the center of the rectangle. Use CIRCLE command Snap to center Enter D and then 17 Construct a hexagon inscribed in a circle of 32 mm diameter, concentric with the 17 mm diameter circle. POLYGON → 6 sides Snap to center Select Inscribed in circle Radius = 16 mm Create a separate layer for the axis. Draw the pitch circle and axis lines. Set the line type scale (LTSCALE) to 0.1. Apply fillets of 10 mm radius to all corners of the rectangle. FILLET → Radius → 10 Draw circles of 10 mm diameter concentric with each fillet and add axis lines. Create the remaining circles using a Rectangular Array. Rows: 2 with spacing 20 mm Columns: 2 with spacing 50 mm Annotate the drawing with proper dimensions. Precautions: Ensure OSNAP and OTRACK are ON Grid snap should be OFF Use ORTHO mode for vertical and horizontal lines Keep Dynamic Input ON at all times Result: The given Figure 3 is successfully drafted with dimensions using AutoCAD 2026.
