Is it possible to scale a whole drawing proportionally by specifying the width of one of the existing lines?

subplane,

 

I second the approach by Peter, working (in)directly on the Stroke Weight.

 

So the answer is (almost) yes.

 

Illy (job description Adobe Ilustrator) is always eager to help, and she is able to calculate the percentage for you from the current and desired Stroke Weight: percentage = 100*desired/current, so in the (Uniform) box you can simply add 00 to the desired Stroke Weight and then type / and then type the current value; for a desired Stroke Weight with decimals, similarly move the decimal separator twice to the right or, with only two decimals just delete the decimal separator, and with only one just delete it and add one 0.

 

 

Hi Peter.

Hi yes you need to convert that to shapes first using expand or outline stroke....regards

Thanks for the help, but I'm not following you. I tried both "Expand" and "Outline Stroke" (what am I supposed to perform that on?) and neither one of those things let me specify the length of a line to scale with the rest of the drawing.

You can't scale it directly by specifying a width (or length) of one object, assuming the drawing has more than one. You would need to determine the percentage of increase or decrease that you want.

 

You don't need to expand anything. If you want stroke weights to increase or decrease proportionally with the drawing, activate Scale Strokes and Effects in Preferences > General, the flyout menu in the Transform panel, or the More Options (…) section of the Properties panel (with at least one object selected).

 

Go to the Object menu > Transform > Scale, and enter the desired percentage into the Uniform field and click OK.

Hi yourself, Jacob.

 

It works equally well to enter the desired final dimension × 100 of any path, shape, or stroke, then / , then the current dimension. All dimensions must, of course, be in the same units.

 

My logic was that (almost) yes is not yes, therefore no, but I suppose that one could argue that (almost) yes is closer to yes than no, therefore yes. In any case, it is not possible to select a path, assign a new value to it, and have multiple paths scale accordingly; it simply requires a bit of rudimentary mathematics.

Indeed, Peter.

 

Maybe this is the first case ever where it is possible, and suitable, to say:

 

The long answer is yes and no.

 

Or no and yes.

 

This is becoming difficult.

Thank you so much for this solution! If only I remembered math class in grade school in the first place. I'm not quite following about Stroke Weight (I'm just trying to scale lengths and widths, stroke isn't important in this case), but that little formula did exactly the trick to figure out the percentage to scale everything at. Thanks again!
