Hello all,
I am trying to align five paths so that the center of each is located on a
vertex of a regular pentagon (or, equivalently, the point of a five-pointed
star). The paths are all different sizes. Does anyone know of a way to do
this?
Thanks a lot,

I guess you need it to be 100% exact. You could do this with a script.
If you can live with a little bit of error, you can align the paths to a
cross (just two perpendicular lines which are centered on each other).
Now you can select the path and the cross and move this until the center
of the cross is where you want it to be (the cross just gives you visual
feedback where the center of the path is). Delete the cross afterwards
and you're done.
If you need to find the center of a vertex, just school geometry: Align
two circles to the endpoints (they must be large enough to intersect),
connect the intersection points with a line and you'll have the center.
Not really 100% perfect but usually good enough.
Another solution might be to draw these parts in a CAD program which can
do this and export in a format that Inkscape can read.
Regards,

Just draw a star with star tool and position your path at the tips. If
you need absolute precision, you can turn on snapping to object paths
and snap them exactly to the star tips.

Thanks for the replies! My problem is that I need to align the *center* of
each path to the points of the star. Since there is not necessarily a node
at the exact center of each path, I don't think the snapping approach will
work.
Cheers,

Actually, it should snap the object's rotation center (which you can
place anywhere you want) as you drag the object. Diederik, what do you
think? I was under the impression that it already does, but looks like
it's not, so this needs to be enabled.

I just tried this, and indeed the rotation center is not snapped.
Thanks anyway for the help,

This now works in SVN - thanks Diederik!

Yep, that's a bug. At some point we
decided not to snap the path nodes
in the selector tool (see
http://sourceforge.net/tracker/?func=detail&aid=1589436&group_id=...),
but the way it's implemented now the center of a path-object doesn't
snap either. It did work however for shapes, at least in recent versions.
I have just fixed this, but it will take a couple of days before I
commit the patch (due to other pending changes).

Hi,
Snapping the object's rotation center is quite useful in some cases, but
it can also be confusing in other cases. Imagine trying to align a
square to a grid, with the square dimensions being an uneven multiple of
the grid's pitch. While dragging the square around, it snaps it's edges
to the grid as expected. But then suddenly it snaps while none of its
edges appear to be aligned..... It's the center that is snapping, but
there is no visual clue or anything pointing in that direction. Even
after all the time I've spend plowing through the snapping code, it
still fools me from time to time. In general, we should only snap points
that have a visual clue, such as a corner of a bounding box, a tip of a
star, or a node at a salient point of a path. Snapping nodes at a smooth
path or object center's, which don't have a visual clue, can be confusing.
Maybe an additional checkbox in the snapping preferences dialog would be
justified in this case: to enable/disable snapping the rotation center.
By default it should be disabled. Too much checkboxes (like in v0.45.1)
is confusing, but I think we need one for this. Does any one think
otherwise or know of a better way?
In SVN the snapping dialog has changed for the better I hope, but
feedback is always appreciated!

well... if you start with a STAR... using the star drawing tool...
you can draw in five lines, one from each point of the star,
to the opposite inward angle vertex... and you'll have five
lines intersecting at the center of that star, which you can
then erase. That should give you a start.
