i have a Compound Path in Illustrator, that needs to be scaled in line thickness/weight without changing outer Bounds.

This Path was initially created by outlining a simple stroke. The Path consists of points and is closed

(only part of image is displayed here)

There are also the hard requirements:

  • Number of points must be exactly equal from the original to scaled version
  • The Layers and Elements hierarchy of scaled path must be exactly equal to original one.

How can this be done?

Trying to simply apply Stroke Weight results in a correct looking Version, but fails matching the requirements above when Outline Stroke is applied.
This adds a completely new set of points not only in position but also in point count:

Thank you!

  • Hi. Welcome to GDSE, while offset will probably work, converting strokes to outlines is destructive. It would have been better to have kept a copy of the original stroked version. Then you could simply increase the stroke thickness before converting to outlines.

  • @BillyKerr Yes this was exactly what i was doing. I have the original stroke with thickness 0. Increasing Thickness and Outlining creates the above points differently.

As @joojaa mentions in the comment....

Remove the new stoke and choose Object > Path > Offset and enter a value half the size of the stroke you removed.
