Parallel curves ?

[missenard_yves@adobeforums.com]

Hello,
I'd simply like to draw parallel curves (i.e. constant distance between my two curves). But I still can't find the way to. Any idea ?
Thanks for answer.

Missenard,

One way to do this would be to draw a curve, give it a heavy stroke, expand, ungroup, then remove unwanted line segments.

Hmm, works, but then you would need a centerline. still, never thought of that!

[Harron_K._Appleman@adobeforums.com]

After ungrouping, you should be able to delete the center path.

Also, the last step, more accurately, should be "remove unwanted fills and line segments."

Another way is to draw the path with a heavy stroke, outline it, change fill to stroke, erase a bit of each end line joining the curves, and delete the new anchor points.

I guess it's really true, nobody reads the first post.

[Jacob_Bugge@adobeforums.com]

Of course it is true. No one reads posts #6&7 either, so I may put it here: there is a difference between expand and outline, no centre line to remove with the latter.

Jacob,

...no centre line to remove with the latter.




Really? Take a look in outline mode.

But, yes, I agree with you. Although, in this case, they may be functionally equivalent, expand and outline stroke are not exactly the same. I think I like your way better.

That was good for a laugh, though.

only if the path had a fill. otherwise, no centerline.

Aha...

1. Rectangle tool. Draw a small rectangle. No fill. Simple stroke.

2. DirectSelect left and right segments. Delete.

3. Drag the remainder to the Brushes Palette. Chose New Art Brush.

4. Draw a curvey path. Apply the Brush. Change the stroke weight of the spine path to adjust the scaling of the parallel lines.

Works for curvey paths. Yields goofy overlaps at sharp corners. (They can be cleaned up by Expanding Appearance, followed by Trim Pathfinder. Then delete unwanted segments.)

Wow, many and quicky answers, thanks guys ! Ok, I think the last one is the best (answer 10) ; I have found it too yesterday evening, works great. I hadn't any idea on how to clean the overlaps, but thanks to James, that's ok.
Thanks again

Who said I didn't read the first answer ? :)))))))
Thanks you all.

Also, of course, you can make any type of line or arc, establish it's center point, then Control C copy, then Control F paste in front, then hold down Shift to constrain and make the arc or line any size you wish in relationg to the original and center and it's parallel and proper ratio to original, inside or outside or compound.

Simply wonderful :)
