How do you calculate CAD scale?
Determine Target Drawing Scale
- Divide the largest length of your design (in feet) by the length of paper you have to work with (in inches) and multiply by 12.
- (240’/16”) x 12 = scale factor of 180.
What is the scale factor of 1 30?
> Thanks in advance! No, 1:30 is a unitless ratio and means just what it says, 1 “anything” equals 30 of the same “anythings” – so 1 inch = 30 inches, 1 mm = 30mm, etc. 1″ = 30′-0″ is the same as 1″ = 360″, or 1:360.
What is the scale factor for 3 32?
Architectural Scales
| Drawing Scale | Scale Factor | Viewport Scale |
|---|---|---|
| 3/32″ = 1′-0″ | 128 | 1/128xp |
| 1/8″ = 1′-0″ | 96 | 1/96xp |
| 3/16″ = 1′-0″ | 64 | 1/64xp |
| 1/4″ = 1′-0″ | 48 | 1/48xp |
How do you do scale ratios?
To find the scale factor of the drawing to the actual fence, first write a ratio that compares of the two quantities. Next, compare the quantities using the same units. Convert feet to inches by multiplying the ratio by the conversion rate of 1 ft = 12 in. Then, simplify the fraction.
How do I scale ratio in AutoCAD?
How to scale up in AutoCAD – Window select the object(s), type SCALE, and then specify a number larger than 1. Hit Enter. The size of the object(s) will SCALE UP by that scale factor. Refer to Figure 1 to see the differences in scale factors.
How do you read an engineering scale?
A whole number or fraction to the left or right of the number line indicates the scale those numbers represent. Engineer scales have numbers that run incrementally from left to right. The whole number to the left of the number line indicates the scale those numbers represent. The scale marked “16” is a standard ruler.
How is architectural scale calculated?
Set the ratio as the size of the design on the paper to the size of the design in real life. In the example, 1.5 feet to 40 feet. Evaluate the ratio to find the scale. In the example, 1.5 feet divided by 40 feet equals 0.0375, so the scale of the object is 0.0375 to 1.0.
How to convert a drawing scale to a scale factor?
To convert an architectural drawing scale to a scale factor: Select the desired scale. 1/8″ = 1′-0″. Invert the fraction and multiply by 12. 8/1 x 12 = Scale Factor 96.
What are the different types of drawing scale?
Engineering Scales Drawing Scale Scale Factor Viewport Scale 1″ = 10′-0″ 120 1/120xp 1″ = 20′-0″ 240 1/240xp 1″ = 30′-0″ 360 1/360xp 1″ = 40′-0″ 480 1/480xp
Which is the correct scale for a 3D model?
With this in mind, a 1:1 (“one to one”) scale is the real world scale of everything, and the scale that we draw and 3D model in when using CAD and 3D programmes (…more on this below).

How to reduce a scale factor to an even ratio?
When the scale factor is not in an even 1:n ratio it will need to be reduced to 1:n. Use our ratio calculator to reduce a ratio. A ratio can also be reduced by dividing both the numerator and the denominator by the numerator. For example: 2/3 can be reduced by dividing both numbers by 2, which would be 1/1.5 or 1:1.5.
