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)

- If the section(Cutting) plane is inclined to HP – Draw the sectional top view
- 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**

Teseare useful ye need more tips for solid projections

Thank u

tis inf is useful………. thanks

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

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

thanks it is useful

i want to learn section of solids , development

sir,

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

I Like It But it is not understood to me very perfactly

so please contact at my id bktarunlovesgodfather@gmail.com

i am not clear with this topic pls help me

Need more tips

i didn’t understand after the completeion of axis length

thnx but exp not given

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

i am yet done this topic will i clear the paper

Can you show any demo to draw

section of solids topic was very easy to understand and also very useful to get good score in examination
