When using a CAD program. Change scale.

Was 43.518666. Want it to be 100. So

100/43.518666 = 2.2978645531092337

This works perfectly.

Now using Adobe Illustrator. To change scale I need a % number. What is it?

Note:
230% is too big.
44% is too small.

Question?
Original drawing is 44 inches. Want new drawing to be 100 inches. What is percentage?

Answer:
To find the percentage increase from the original drawing size (44 inches) to the new drawing size (100 inches), you can use the following formula:
[\text{Percentage Increase} = \left( \frac{\text{New Size} - \text{Original Size}}{\text{Original Size}} \right) \times 100]
Substituting in the values:
[\text{Percentage Increase} = \left( \frac{100 - 44}{44} \right) \times 100]
[= \left( \frac{56}{44} \right) \times 100]
[= 1.2727 \times 100]
[= 127.27%]
So, the percentage increase from a 44-inch drawing to a 100-inch drawing is approximately 127.27%.

No idea how the computer figures this out? This is how I figure?

Copy and paste calculator.

100-43.518666 = 56.481334

56.481334/43.518666 = 1.2978645531092334

So 130% Wish me luck?

Come on Marty. Lets be accurate here.

Something has gone very wrong. No idea what I am doing?

Adobe Illustrator CC. Using inches. Measure with measure tool 1.7136". Want 100' to be 2.5" because scale is 1" = 40'

2.5/1.7136 = 1.4589169000933706

145.89169000933706%

Think a newer version of Adobe Illustrator might have a better dimension tool?

 

[marty]

Got back from print shop. 11x17 paper. 1" = 40' scale looks perfect on my triangle ruler.

So 145.89169000933706% is the answer to my question. Sorry about my math confusion.

Sad news in Marty's world of CAD.

Adobe Illustrator ain't CAD.
It is a drag and drop vector graphics Illustrator.
(also requires Windoze OS)

In AutoCAD scale is set in viewports created in paper space.

Model space where the actual drawing or modeling takes place is always done full scale.

The reason scale is set in viewports is you can create unlimited viewports and assign a unique scale to each one.

I've been using AutoCAD since 1996 release 10 before Windows. If you have anymore questions let me know.
