How come this simple feature is not in illustrator
Please enable this

PLEASE!

I can not believe something THIS BASIC has NOT been implemented yet. I break a path and the align jumps to center. SERIOUSLY???

Why isn't this the top voted request? Am I missing something here ?

When using the PEN, I can't align the stroke to interior or exterior, I can only use the stroke centred.

If I create a square, I can use the stroke in the three ways.

Could be an error, or what happen to the pen, that I can not align the stroke ¿?

IT DOESN'T MAKE SENSE !!!! Just tell us only one reason why aligning stroke to inside an open path doesn't work ?

YES PLEASE! This will also be helpful when dealing with pixel-perfect artwork. As mentioned, aligning an unclosed path to a shape doesn't work, and makes working in pixel mode a pain - throws alot of things off. If the path were able to flip to a side, it would be much easier workflow! I get that it has never been available, but back in the day, things were much more limiting. Seems like it shouldn't take much to offer this option. Pretty please!

Also, it would be handy to be able to have a stroke offset along a path - like say 15 pixels to the left side of the path, etc. Would be handy in many occurances. But first and foremost, is the afforementioned request. Seems well past time to offer that functionality.

This is very neccessary, because if you have gradient stroke outside artwork, then part of the stroke covers the artwork. I would really need to have gradient on outer stroke and with all three alignment options for the gradient.

Please make this possible. I have got the logic behind it explained, but from a user perspective I just want to accomplish the gradient stroke (with all alignment options), on the stroke outside, so artwork is not covered. So even if it is not "logic", then anyone using this would expect to be able to use any of the greyed out options, and get the same look on the stroke when it is outside as it is when it is centered.

Better workaround: create a Width Profile using the Width Tool that strokes only to one side.

I am posting this in case it's helpful – I still agree with this suggestion that open paths should allow "left" or "right" path alignment (based on direction of path).

Alternatively, Adobe could allow us to offset a path one way or another (as an effect, say)? The current Offset Path, applied to an open path, will offset it in both directions.

Agreed. It could use the same "inside" and "outside" stroke toggles. But on an open path, those could even be arbitrarily applied as left of path and right of path. Virgil's workaround suggestion is fine, but is inaccurate with scaling, either built as an art brush or pattern brush. I.e. when a 1pt "lopsided" stroke is made, it's applied a bit closer to 2pt width.

Workaround: create a Brush that is lopsided (i.e. has colour to only one side).

A stroke can only currently be set to the default (center, I guess your call it) of an open path. It would be nice to allow it to be set to the inside or outside. Since an open party doesn’t really have an inside or outside, I imagine it would work in a way similar to how the direction of an arrowhead can be reversed. This would save me a lot of time when working with graphics that require aligned open and closed paths.

Please please add this Adobe, it will make my life easier.

This would be a welcome feature! So far I've had to do it using the width tool which is a bit of a pain as you have to adjust each point.

YES. I have spent hours trying to find a way to stroke one side of my complex logo.

New version and still broken, even after getting an email response from Adobe support saying that the problem was fixed?

Please fix this. It is beyond annoying to have to change outer/inner stroke to a center stroke and then manually offset it using effects. Just do it automatically for us please.

Just shocking that we can't align strokes to open paths as we choose!

All three stroke gradient types should be applicable to all three stroke alignments. At the moment, I can only use all three gradient types if the stroke is aligned to the center of the path. If I need to make for instance a circular gradient on a stroke (the second gradient option), I am forced to align the stroke to center.

Please make this a feature. Align stroke on open paths is an important feature that I would very much like to see.

It is strange that this is not possible in Illustrator, since it is possible in Photoshop.
