How can I place multiple objects on a curve?

As far as I know it's not possible. You can use markers, but it's not exactly the same you need.
Text can be placed on curves and every character is rotated following the curve, but there isn't at the moment something that can do that with individual objects without deforming them (curve and envelope distort LPEs deform the shapes)

Thank you for your answer, Guillermo. It's very noticeable.

actually.. you can eventually fake it..
1. put your objects inline with the desired space between them using "Align and Distribute (Shift+Ctrl+A)
2. make sure they are all paths (Path menu>Object to path Shift+Ctrl+C)
3. select all your objects and Path menu>Union (Ctrl++) or Path menu>Combine (Ctrl+K)
4. Path Effect Editor > Pattern Along Path

you will eventually get something close to the effect you want, but as Gez said some shapes might be a bit deformed depending on your path.

Thank you, Rico.

It is very useful. Especially when you break paths back (Ctrl+Shift+K) after this... And if you want to save fills of objects you can duplicate objects before combining them... so that after "pattern along path" you can copy-paste fills from duplicates. Unfortunately this can be done in years with billion of objects... oh... computers are very slow ;)

Yesterday I have wrote extension for Inkscape which can place multiple objects on a path...

This have been done with it:

If someone is interested in extension I can send it to him.

Hey, good work!
Good news: Alexandre Prokoudine proposed your extension to be added in the default inkscape installation.
If nobody objects, it is possible that your extension makes it for 0.47!

Wow, cool! :)

But for now it has some problems.... I think that it is not my fault and I believe that we can solve them ;)

Thanks, Guillermo.

I would love to have a copy of that extension. Just what I am looking for. I will try and find you....

DeepSpin, you can view a topic about the extension on a Russian forum (http://linuxgraphics.ru/forum/viewthread.php?thread_id=545)
or you can just download the extension from http://www.hotlinkfiles.com/files/2460676_imfzd/placeonpath.ink_025717.7z

You should copy three files in archive to "...inkscape/share/extensions/".

Thanks you.

Thanks very much. I'm afraid i don't read Russian. Sorry.

I'm having trouble making it work. I get this error.

raceback (most recent call last):
  File "/home/dave/.inkscape/extensions/placeonpath.py", line 2, in <module>
    import inkex, simpletransformed, pathmodifier, cubicsuperpath, bezmisc, math
ImportError: No module named inkex

Do you have any ideas?

Sorry for this. Try to put it into "/usr/share/inkscape/extensions/" folder.

Perfect. Thank you so much for taking the time.

All the best ~ Dave

You are welcome!

Hello Dave or User!

I find your extension very appealing for me. I have written an extension that duplicates boxes and groups them with a corresponding number. I need to digitize a map. Anyway, scarse documentation left me spending a lot of time for a simple task, and now I have found that I would need something like your extension.

The link you have posted is outdated...http://www.hotlinkfiles.com/files/2460676_imfzd/placeonpath.ink_025717.7z

Could you please upload the file again ? Or if anybody else has this file, please upload it so that other users can enjoy as well

Thank you!

Seems that hotlinkfiles have changed all of their link addresses. Unfortunately.

This link can help you: http://www.hotlinkfiles.com/files/2338101_wqe6m/placeonpath.ink_025717.7z

You are welcome!

Hello again. I modified your script a little. Everything that I changed is found both in the code and at the beginning of placeonpath.py as comment.

Please check out the zip file here and please delete it after downloading and using.

Hello, Victor.

I have downloaded and deleted the script.

I have no time to check it, but I believe that your modifications are useful. Thanks. I will see them later.

Hope other will help. As you said in your code : feedback!

Everybody, join the projects you find useful and help, if you don't know to code, try testing. :D Sometimes it's fun to push a program to it's limit.

1. changed your script, so now it can be installed in the user's home folder
2. added gplv2 header to your file
3. removed useless code

Tested your script with 2 straight lines at 90 degree angle. Works.

Have a great day!

great effort, but guys..

host it somewhere permanently, for easy obtaining of the code.
I tell nor about me - I have a copy, but for someone else interested, since the script can be useful for many ppl.

@user - the link at your blog also dead (http://pozitiv.org.ru/2009/04/place-objects-on-path-in-inkscape.html)

Cheers, Oleg

Thanks, Oleg.

Extension can be obtained from http://sites.google.com/site/placeonpath/

Two bugs fixed :)

Great!

I add that site onto Inkscape wiki page about extensions. I think you won't
resist? :)

best wishes!

Sure, thanks! :)

@(user, Victor and Oleg) - many thanks to all of you for this extension and making it available again!
