Regarding the drawing scale
Thread Content
Dear experts, please take a look at the following scale and explain what it means. 1. Scale 1 2. Scale 2 3. Scale 3
Experts, please share your thoughts – this is the scale on the foreign Aramco drawings, and it’s really hard to understand.
? Where is the confusion? Just looking at the scale, there seems to be nothing abnormal
I don’t understand what you’re asking; it’s just a scale.
The linear scale factor doesn’t correspond to the numerical scale factor, right? Take a look at how to change the linear scale to a numerical scale
I mean, does 1:75 necessarily require 75 segments? I don’t know where it doesn’t match
Scale 1: The linear scale has 7.5 segments, each segment being 1 cm, representing 10 m of actual distance. That is: 1 cm = 10 m, 1 cm = 1000 cm; hence, the scale is 1:1000. Where does the numerical scale of 1:750 at the bottom of the linear scale come from? The case of scale 2 is the same as scale 1. Scale 3: The linear scale has 5 segments, each 1 cm long, representing 1 meter of actual distance. That is: 1 cm = 1 m, 1 cm = 100 cm; hence, the ratio is 1:100. Where does the numerical scale of 1:50 at the bottom of the linear scale come from?
I understand your confusion now. When I was looking at it, I simply treated the line segment on top as a ruler. According to your algorithm, scale 1 also has no standard size unit. How do you think 1 cm is equal to 10 m?

Expert, please study all the scales in this drawing
Is there no expert who can explain this issue?
