Types of Line in Drawing..
- VISIBLE LINE
- DIMENSION LINE
- EXTENSION LINE
- LEADE LINE
- CENTER LINE
- PLAN VIEW
- HIDDEN LINE
1. VISIBLE LINE
Engineering Drawing (Engineering Mein): Visible line engineering drawing mein ek prakar ka rekha hota hai
jo kisi 3D object ke kisi specific part ya feature ko dikhata hai. Is line ko usually solid (thos) ya dark line se represent kiya jata hai.
taki yeh aasani se distinguish kiya ja sake. Yeh line un parts ko represent karti hai jo object ke exterior mein hain aur clearly dikhti hain.

2. DIMENSION LINE
“Dimension line” ek drawing ye blueprint ke context mein ek important element hota hai. Iska main kaam hota hai kisi bhi object ya structure ki size, length, width, ya height ko measure karke dikhana.
Yeh line usually ek straight line hoti hai jo object ke specific dimension ko represent karti hai. Dimension line, arrowheads aur dimension values (jaise ki numerical measurements) ke saath hoti hai.
Yeh samjhane ke liye ki kis dimension ko kis line se measure kiya ja raha hai, arrows ka upayog kiya jata hai.
dimension line, engineering drawings, architectural plans, ya kisi bhi technical drawing mein size aur dimensions ko saaf dikhane ke liye istemal hoti hai. Ye drawings construction, manufacturing, ya design ke kshetra mein upayogi hoti hain.

3. EXTENSION LINE
“Extension line” ek technical drawing ya blueprinting ke context mein ek important concept hai. Extension lines, yaad dilane ke liye, usually dotted lines hote hain jo kisi particular feature, dimension, ya object ko highlight karne aur uski measurement ya position indicate karne ke liye istemal hoti hain. Extension lines ka istemal drawing mein clarity aur accuracy maintain karne ke liye hota hai.
Extension lines ki kuch key characteristics hain:
- Dotted Lines: Extension lines usually dotted lines hoti hain, jisse ki unka main object se easily distinguish kiya ja sake.
- Origin Point: Extension lines kisi specific point se shuru hoti hain, jaise ki object ke edge se ya kisi specific reference point se.
- Direction: Extension lines object ya dimension ke direction mein point karti hain, jisse ke samajhna ho ki ye kis feature ya dimension ko refer kar rahi hain.
- Termination Points: Extension lines ek arrowhead ya crosshair se end hoti hain, jisse object ya dimension ke endpoint ko indicate kiya ja sake.
Extension lines drawing mein clarity maintain karne aur dimensions ya features ko correctly interpret karne mein madad karti hain. Extension lines ko often dimension lines (jis se measurements li jati hain) ke sath use kiya jata hai taki ye clearly dikhaye ki dimension kis feature ya object ko refer kar rahi hai.
Yadi aap ek technical drawing ya blueprint taiyar kar rahe hain, to extension lines ko sahi tarike se use karna important hai taki aapka message clear ho aur kisi bhi confusion se bacha ja sake.

4. LEADER LINE
“Leader Line” ek technical drawing term hai jo engineering, architecture, ya kisi bhi technical documentation mein istemal hota hai. Leader lines drawings mein information ko indicate karne aur point out karne ke liye istemal hoti hai. Yeh generally ek line hoti hai jo kisi specific object, dimension, ya label ki taraf point karti hai. Leader lines drawings ko clear aur organized banati hai taki viewers ya workers ko samajhne mein madadgar ho.
Leader lines ki kuch important baatein:
- Line Style: Leader lines kisi specific line style mein hoti hain, jaise ki dashed (kutti hui) ya solid (khadi) line. Isse unhe asani se pehchana ja sakta hai.
- Arrowheads: Leader lines ke ends par arrows (teer) bhi ho sakte hain jo indicate karte hain ki line kis direction mein point kar rahi hai.
- Text or Labels: Leader lines ke sath text ya labels bhi hoti hain jo batati hain ki line kis object ya dimension ko refer kar rahi hai.
Leader lines drawings mein kisi bhi specific object ya dimension ko highlight karne ke liye use hoti hain. For example, agar aap ek architectural drawing dekh rahe hain to leader lines doors, windows, ya measurements ko highlight karne ke liye istemal ho sakti hai.
Mukhya roop se, leader lines drawings ko organized aur samajhne mein madadgar banati hai taki koi bhi viewer ya worker asani se samajh sake ki drawing mein kis chiz ki baat ho rahi hai.

5. CENTER LINE
“Center line” ek aise term hai jo kisi bhi cheez, shape, ya object ke center ko represent karta hai. Yeh term kai alag alag context me istemal hota hai, jaise ki engineering, geometry, ya anya fields me. Yahan kuch examples diye gaye hain:
- Engineering: Engineering me, center line ek design ya blueprint me istemal hota hai, jisse dikhaya jata hai ki kisi object ya component ka center kahan hota hai. Isse manufacturing aur assembly me madad milti hai.
- Geometry: Geometry me, center line ek shape ya figure ke center ko represent karta hai. For example, agar aap ek circle ka center dhundh rahe hain, toh us circle ke center line uske center point ko darust dikhayegi.
Iske alawa, center line ka istemal aur bhi alag alag context me ho sakta hai, lekin mukhya roop se yeh term kisi cheez ya object ke center ko darust dikhane aur samjhane ke liye istemal hota hai.
6. PLAN VIEW
ek engineering, architecture, aur design me istemal hone wala term hai, jo ek project ya object ki layout ya structure ko ek bird’s-eye view ya top-down perspective se dikhata hai. Isse project ya object ka overall design aur arrangement samjhne me madad milti hai.
Plan view ke bare me adhik jankari dene ke liye, yahaan kuch mukhya points hain:
- Bird’s-eye View (Pakshi Drishti): Plan view ek aisi drishti hai jisme object ya area ko upar se dekha jata hai, jaise ki ek pakshi udan ke dauraan dekhta hai. Isse object ya area ka pura span aur layout saaf dikhata hai.
- Blueprints aur Designs: Plan view ka istemal blueprint banana, architecture designs tayyar karne, aur civil engineering projects plan karne ke liye hota hai. Isse architects, engineers, aur designers project ke layout aur dimensions ko samajh sakte hain.
- Scale: Plan view me har object ka scale ya proportion dhyan me rakha jata hai. Yani, ek chhoti building aur badi building ke plan view me unke asli proportions ko sahi tarah se represent kiya jata hai.
- Symmetry aur Arrangement: Plan view se object ya area ke symmetry aur arrangement ko samjhne me madad milti hai. Isse samjha ja sakta hai ki kaise rooms, corridors, ya components ek dusre ke saath jude hain.
- Navigation: Plan view aksar buildings, campuses, ya public spaces ke maps banane ke liye bhi istemal hota hai. Logon ko kisi jagah me kaise ghumna hai aur kahaan kya hai, ye samjhane ke liye bhi plan view ka istemal hota hai.
- Color Coding aur Labels: Plan view me kuchh important features ko color coding aur labels ke through highlight kiya jata hai, taaki unhe aasani se pehchana ja sake.
Plan view ek bahut mahatvapurnn tool hai jo spatial understanding aur design planning me madad karti hai. Iska istemal alag-alag industries mein hota hai, jaise ki architecture, engineering, urban planning, landscaping, aur interior design mein.

7. HIDDEN LINE
ek computer-aided design (CAD) ya drafting ke context mein ek aham concept hai. Iska mukhya uddeshya hota hai 3D objects ko 2D drawings mein darust tarike se darust dikhana. Yani ki, agar aap kisi 3D object ka 2D blueprint taiyar kar rahe hain, to hidden lines ka istemal uss sthan par kiya jata hai jahan ek object ke kuch hisse doosre object ke peeche chhupi hui hoti hain.
Hidden lines, ek 3D object ke aise hisson ko darust dikhane mein madad karte hain jo kisi doosre object ya surface ke peeche hain aur seedha nazar nahin aate hain. Jab aap ek 3D object ko 2D drawing mein convert karte hain, to aapko dikhana hota hai ki konsi lines visible hain aur konsi lines hidden hain.
Iske liye, CAD software mein hidden line removal algorithms ka istemal hota hai jo automatically hidden lines ko remove karke 2D drawing ko taiyar karte hain. Isse engineers aur architects apne designs ko sahi dhang se analyze kar sakte hain.
Toh, hidden lines ek important concept hain jo CAD aur drafting mein istemal hota hai taki 3D objects ko 2D drawings mein sahi tarah se represent kiya ja sake.
