Tips for Section of Solids

As per Anna University syllabus this topic is confined only to solids kept in vertical position

i.e Axis perpendicular to HP therefore draw the top view (TRUE SHAPE)

  1. If the section(Cutting) plane is inclined to HP – Draw the sectional top view
  2. If the Section (Cutting) plane is inclined to VP – Draw the sectional front view

Prism

Max no of point on sectional view is equal to the number of side

Minimum depends on the inclination of section plane

i.e:- Pentagonal max. is 5

Students often include intersection of sectional plane and the solid axis which is wrong

 

Pyramid and Cone

  • Join the intersection of points and slant edges by straight line for pyramid
  • Join the intersection of points and slant edges by smooth curve for cones
  • Don’t forget to denote the auxiliary plane used for getting the true shape of the section
  • If you get the true shape by projecting the original front view then new plane will be AVP (Auxiliary Vertical Plane)
  • If you get the true shape by projecting the original top view then new plane will be AIP (Auxiliary Inclined Plane)

When the intersection points is on the axis

Transfer it to extreme slant edge or contour and project it down ward to get the top view in the respective edge/generator

  1. Teseare useful ye need more tips for solid projections

    Thank u

  2. tis inf is useful………. thanks

  3. tips are very useful for us but a example should be given.

  4. i am not clear about this.please give me some more instructions about this

  5. i want to learn section of solids , development

  6. sir,
    i need some pratical demonstration videos for the section of solids and development of surface.

  7. I Like It But it is not understood to me very perfactly
    so please contact at my id bktarunlovesgodfather@gmail.com

  8. i am not clear with this topic pls help me

  9. Need more tips

  10. i didn’t understand after the completeion of axis length

  11. thnx but exp not given

  12. i am not clear about this.please give me some more instructions about this

  13. i am yet done this topic will i clear the paper
