Offset Path Won't Work
I am using Adobe Illustrator CC 2018 and can't get negative offset path values to work. I am trying to create an offset path in the negatives in text that I have created outlines on. When I do positive numbers, the offset path gets bigger (as it should) When I do negative offset values, the object is duplicated but at the exact same size. I have tried using the offset path tool from both the 'object' and 'effect' tabs and neither is giving me results. I have also tried negative values ranging from -1 to -16,000... there is no change.
I am having the same issue. I wasn't able to follow the steps provided by Pen (not sure how to get a stroke with no fill...) but using the stroke to make an object appear thinner did work. Then I just expanded the shape with fill and stroke, then deleted the part of the shape that used to be the stroke.
I'm having this exact issue today. it's driving me crazy.
A temporary workaround:
1) Clone the object and paste in front
2) Apply a stroke with a fill of "none" and set the stroke to "inside" the path in the stroke palette. Adjust stroke width as needed to visually "inset" to your desired appearance
3) From the menu, release this newly-created compound path
4) From the menu, Expand Appearance of this object. You should now have a new object with a "thinner" appearance that mirrors what "offset path" with a negative value would normally do
Experiencing the same issue in Illustrator v. 24.1, updated just a few days ago.
Exactly as original post describes - Negative values for offset path do not yield expected results. For logo design, this is kind of a mission-critical feature. Frequently requested to make a mark "thinner" when a lighter weight version of the font does not exist. Offset path with negative values is the best (and only way I am aware of) to do so.
Please fix this.
