algorithmic modeling for Rhino
Kindly, i use area and scale components as see in attached picture.
the total area = 60
the scale factor = 0.5
the area after scaling = 15.0
Why ??? It should be 30
Please anyone answer me ???
If you have a rectangle that is 6 x 10 it has an area of 60
If you scale that rectangle by 0.5 it will be 3 x 5 which has an area of 15
No, area is measured in square units. If you scale a curve by a factor of 0.5 it will become half as long, when you scale a surface by a factor of 0.5 it will become one quarter as big. If you scale a solid by a factor of a half, it will become one-eighth as voluminous.
This is the relationship between area and scale factor:
A' = A * f²
The 2 is there for the same reason areas are written as m².
So if you wish to make an area half as big, the scale factor you're after is:
f² = 0.5
f = √0.5 = 0.70710678118654752440084436210485
