AutoCAD Units & Scale Setting | Feet, mm, Inches Explained (Complete Guide)
Powered by CivMasterPro
AutoCAD mein sabse common aur critical mistake hoti hai — wrong unit aur scale setting. Agar aapne shuru mein unit galat set kar diya, to pura drawing galat ho sakta hai.
English: Units and scale are the foundation of any accurate AutoCAD drawing.
Hindi: AutoCAD mein sahi unit aur scale hi accurate drawing ki foundation hoti hai.
đ 1. Units kya hote hain? (Understanding Units)
Units define karte hain ki aapki drawing kis measurement system mein hai:
- mm (millimeter)
- meter
- feet
- inches
đ Agar units mismatch ho gaye to dimension galat show hoga.
⚙️ 2. UNITS Command ka use kaise karein
Command: UNITS
- Type → Decimal / Architectural
- Precision → required level
- Insertion Scale → mm / feet
Hindi: UNITS command se aap pura drawing ka measurement system control karte hain.
đ 3. Decimal vs Architectural Units
| Type | Use |
|---|---|
| Decimal | mm, meter (Engineering work) |
| Architectural | Feet & inches (Building drawings) |
đ Wrong unit type = wrong dimension display
đ 4. Scale kya hota hai?
Scale ka matlab hota hai drawing ka size real size ke comparison mein.
Example:
- 1:1 → actual size
- 1:100 → reduced size
đ AutoCAD mein mostly drawing 1:1 mein banayi jati hai.
⚠️ 5. Scale Factor ka Role
| Drawing Unit | Scale Factor |
|---|---|
| Feet | 1 |
| Inches | 12 |
| mm | 1 |
đ Agar scale factor galat set hai to dimension automatically wrong show hoga.
đ ️ 6. Common Unit & Scale Mistakes
- mm drawing + feet dimension
- Scale factor 12 instead of 1
- Decimal vs Architectural confusion
đ Ye mistakes site par major issue create karti hain.
đ§ 7. Real Site Example
Ek engineer ne drawing mm mein banayi aur dimension feet mein set kiya.
- Wrong BOQ
- Material wastage
- Execution delay
đ Sirf UNITS aur scale fix karne se problem solve ho gayi.
đ§ 8. Best Practice (Golden Rules)
- Project start se pehle UNITS set karein
- Always 1:1 drawing karein
- Scale factor check karein
- Dimension style verify karein
