Presentation Transcript

  1. Sectional Drawing It’s a general practice to draw sectional drawings in orthographic projections. This provides orthographic projections more clarity for the purpose of reading an engineering drawing. All slides are animated. From the next slide click once at the beginning of each slide and allow all animations to be performed and then click for the next slide. Sectional Drawing

  2. Sectional Views For objects having many internal surfaces, holes, slots etc., crowding of hidden lines occurs in normal orthographic views. These hidden lines make drawings complicated for interpreting the actual object. To avoid hidden lines imaginary section planes are passed in different orientations, internal surfaces are made visible and then views are taken. Sectional Drawing

  3. Sectional Views: types Full section Skin or Local Section Half section Offset section Aligned section Revolved & Removed section Sectional Drawing
