- An easy approach towards understanding projection of lines.
The projection of a line can be obtained by projecting its end points on planes of projections and then connecting the points of projections. The projected length and inclination of a line, can be different compared to its true length and inclination.
Case 1. Line parallel to a plane
Case 2. Line inclined to a plane
VP:The plane in front of observer is the vertical plane. (VP)or it is also called a Frontal plane.
Front View (FV):The projection on the VP is called the Front View (FV)or Vertical Projection or front elevation or Elevation.
HP:The plane which is Horizontal and perpendicular to VP is Horizontal Plane.
Top View (TV):The projection on the HP is called the Top View (TV)or Horizontal Projection or Plan.
Note:The planes HP and VP are called Principal Planes.
Reference Line:The line of intersection of HP and VP is called reference line, which is denoted by X-Y.

She is writing in mirror manner
Hats off to you Ma'am
Well she is writing normally. The video is then flipped while editing 😂😂
She is explaining so good. She is so clear and perfect. But Can u bring us all the explanations for engineering drawing all the topics? It will help me a lot. I have exams in one month can you bring it for us? It will be lot helpful. Thanks for the videos anyway!!
Armyyyyy 💜💜💜💜
Mam,ive come across lots of videos in these 2days but none of them explained like the way you did!!! Thank you so much mam🙏
just cleared all my doubts.It was a wonderful session.Thank you
Very nice explanation . Thank you
no one could explain this topic better than you . Thank you 🙏
The explanation was very smooth and precise.
Beautiful presentation mam,Thank you so much
Maam, how can there be an inclined image on the planes if the line(in your case that pen). if it is kept the way you demonstrate. if it was so, we would see 2 lines one of length l cos theta and the other of l sin theta
Thanks
wow my every doubt is cleared. goddess of mathematics
Very good explained
Thank you mam
Thanks alot 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
superb explanation.
Thanks a lot
excellent demonstration
Super ma’am
The lecture was so good!
Really very nice explainTion ma'am 🙏👍
Excellent work
Ur explanation is very good 😊
Awesome😊 explanation
Thank you mam
Very helpful.
awesome 💯💯
Comfused totaly
Good explanation 😃
Very nice
Tq mam
Nice explantion but still
I have this doubt
Frm the sentence
"line inclined to hp inclination is projected on vp"
Fine
But the inclination is on horizontal plane vertically
Then it will b line on both the planes!?
**Like the way u confused in xplaning with the inclined position on hp**!??
Tnk u ma'am it was so helpful.
thank up so much mam i am trying hard so understand before this video
Mam plz do vedio on orthographic projection of planes also mam
U r awesooooome Mam
Thank you
Plane figures in space are not represented by
a. three points not on straight line
b. three points on straight line
c. a point and a line
d. two parallel line
Thank you mam
please make the videos of projection of points .your other 8 videos on projection of lines are too good. thanks
Projection of solids
I WISH PLS DO VIDEOS ON PROJECTION OF SOLIDS PLSSSSSSSS
Love you maam, bless you..so clear teaching..hats off maam
You teaching only in English. Great
Its really useful ❤️tqsm mam
Tqsm mam
part3 ?.
At around 16:45 u said if we observ object from top we get plane of that object but at 17:00 u were taking fv as plan,why?
