multiple offset paths / outlines with defined offset?

Hello! Was checking out the forums for an answer to this also - I'm sure there is an exact way to get Illustrator to perform multiple offset paths with a defined offset (hoping someone chimes in here!) - but came across something in a tutorial from Chris Spooner that I think does most of the trick.

Original Path

With path selected open Appearance Panel

With Stroke selected click on Fx

This will pop up a selection window

For this I chose Distort & Transform -> Transform

MAKE SURE YOU CLICK THE PREVIEW BOX TO BE ABLE TO SEE CHANGES IN PROGRESS

Once you get something you like you can leave it editable for later tweaking - or expand appearance.

Seems like a lot you can do once you get your head around it - plus effects can be saved and applied to other shapes etc

Not saying this is the end answer - but wanted to throw in something I just learned.

Good luck!

I have found a way to cut the task of making multiple offset paths in half.

Example: Create a circle. Offset the path twice the distance you want, let's say 50 points (if your desired distance is 25 points.)

Do this again several times so that you have a number of concentric circles 50 points apart.

Now select all the circles in this concentric set and offset their paths at 25 points in just one trip to the offset paths menu.

You now have twice the amount of circles at your desired distance of 25 points between—done in half the time it would take to create the offset paths one at a time.

The feature you're needing is a contour command/tool which is common in other drawing programs but missing in Illustrator:

Corel Draw:

Xara Designer Pro has a similar interactive feature:

Everything in Illustrator is a workaround.

Cumbersome workarounds are possible, but don't match the ease, features (ex: accelleration), or after-the-fact adjustability of a proper contour feature:

You should be able to do a dumb (non-adjustable) workaround by repeatedly applying Offset Path. However, a few versions ago Illustrator's Offset Path command was wrecked by a change which leaves both the original and the new path selected. You can work around that by building an Action which "names" and "un-names" the original each time so that it can be targeted by the Set Selection step. The Action does the following:

1. Sets a Note in the Attributes palette to temporarily flag the selected path as "Original."

2. Performs the Offset Path command.

3. Sets the selection to the path labeled "Original" (thereby deselecting the offset path).

4. Clears the selected path's note (so it is no longer labeled "Original").

5. Selects the Next Object Below (which is the offset path).

After recording the Action, it can be run by repeatedly clicking the Run button. Each time, it offsets a path by the same distance.

Of course the above results in just a set of dumb unrelated paths, so there is no after-the-fact adjustability that automatically updates. You can have some live adjustability by using a Blend between two identical paths which both have Offset Path applied as an Effect, but with different offset distance parameters:

Tolerable, but still doesn't match the capabilities of a proper contour feature:

laden.m,

Is repeating the offset out of the question?

On a Win Machine, you may press Alt+O+P+O (hold Alt and press O then P then O), then the set value and press Enter. After that, you can just repeat the Alt+O+P+O for each new offset.
