slide11. Example 1 : Object has only normal surfaces<br>
slide12. Example 2 : Object has inclined surfaces<br>
slide13. Example 3 : Object has inclined surfaces<br>
slide14. Irregular Curve in Isometric 1. Construct points along the curve in multiview drawing. 2. Locate these points in the isometric view. 3. Sketch the connecting lines. Steps<br>
slide15. Circle & Arc in Isometric 2. Construct an isometric square. 3. Sketch arcs that connect the tangent points. Sketching Steps 1. Locate the center of an ellipse.<br>
slide16. Circle & Arc in Isometric 3. Construct a perpendicular bisector from each tangent point. 4. Locate the four centers. 5. Draw the arcs with these centers and tangent to isometric square. Sketching Steps 2. Construct an isometric square. 1. Locate the center of an ellipse.<br>
