I'm unable to adjust the weight of a path. Here's a 40 sec video (no audio, 1920x1080) that demonstrates I know how to adjust the stroke weight on a path, followed by a demo of it not working when I try to adjust it:
Here's what I do in the video:
First, on a path that allows the change:
Next, on the path that doesn't allow the stroke width to be reduced:
And that's the problem.
What do I need to do to decrease the weight of the path I am trying to adjust?
The usual suspects in cases of a certain similarity are:
1) Align to Pixel Grid, which seems to be ruled out by the X and Y values,
2) Regional & Language setting of decimal point, which seems rules out by the ellipse case,
3) Corrupt preferences, you may try to reversibly Move the folder,
4) Interference from other applications, see list in Item 7 in Other options , with the addition of FontExplorer.
Thanks. I deleted the original prefs file, opened Illustrator, and the problem seems to remain. The other resources you provided are helpful as well, but the problem still remains.
I had another look at the video, or rather a few looks, and it seems that you have something added to the basic width of the straight path, possibly an effect or something created in the Appearance palette/panel.
The ellipse seems to have a basic appearance with a normal Stroke Weight of 2.148pt which you are changing to 10pt and then 0.25pt, and the appearance changes consistently.
However, the straight path has a (basic) Stroke Weight of 0.5pt, much narrower than the apparent width. When you change that to 12pt, the apparent width increases, but only by a factor of 2 - 2.5 (12/0.5 = 24), and when you change to 0.25 the appearance is just about the same as for 0.5pt.
Yes, thank you and I've figured out what has happened. The layers panel included a layer titled "Meridians" and a sublayer titled "<Path>". Each item has an effect applied through the appearance panel, and that is what was causing the problem. I had been meatballing only the <Path> item in the layer panel, which is behind the Meridians layer item. Decreasing <Path> was not noticable because the Meridians layer item was the 5 point weight in front of it... I changed each item to contrasting colors, increased the weight of <Path> to 20pt, and then it was apparent that the Meridian layer effect was the item that needed to be resized.
Somewhere in this process I mistakenly applied the same effect to the Layer and the Path, and that's what caused my little dilemma.
Thanks to you and everyone else who participated in researching this problem. It's solved.
