How to break apart a circle and expand it equally

ktr · Postby **ktr** » Thu Apr 18, 2013 12:07 pm

Hi -

So, new to this discussion forum ... I'm trying to break apart a circle and then spread the pieces out equally. For an example, see:

This shows precisely what I'm trying to accomplish. I understand how to break an image apart (change to path, insert nodes as necessary, break-apart). But I'm not sure how to spread them out such that you'd still have a perfect circle with spaces between segments (and arrows signifying direction to boot).

Any help would be greatly appreciated! Thanks.

Hi

Welcome as a new user on the forum!

No need to break apart a circle for this.

Use circle tool - Click the arc icon - Adjust the start and ends with the start & end dialog - set the start or end marker in the Fill & Stroke menu.
Make a duplicate CTRL + D - adjust ends again - repeat until you got the eight segments in your example.
See Example;

Here is another method with separate broken segments.
(Sometimes circle arc jumps back to sector.)

If you're referring to it jumping when you move the control handles: it's an arc when the mouse is inside the circle, and a segment when it's outside the circle - if you tend to keep the mouse pointer close to the edge of the circle then it will tend to jump back and forth as the mouse crosses the boundary.

Aha! Thank's for the explanation.
Maybe I'm using the manual path constructing way too much that I missed this feature.

Since no one mentioned path effects here's my contribution to this thread.
Easier? Harder? Depends on how many arrows you want, perhaps, and how precise you want the spacing between them. There are several variations of this method to explore - if you wait to convert the arrows to filled paths until after putiing it on the path, you lose the possibility of editing the spacing easily, and you have to apply the arrowheads AFTER converting the LPE to a regular path; but then you can leave the paths as strokes and change some to be dashed as you have in your example.
What do you think?

Thanks everyone for your help! ragstian: I was able to replicate your suggestions easily - I'm amazed how much time I wasted for something so easy

druban: I was able to get yours to work too. It wasn't quite as intuitive, but I definitely think I learned something. Thanks again to everyone!
