**Circle arcs makes drawing of arc simple.**

Depending on the selected objects circle arc produces different results:

1. **Three nodes** selected:[[BR]]
 A new way forming the arc is created following the order of the nodes' selection. 
1. **One way** selected:[[BR]]
 The arc is "fused" into the selected way between its' last three nodes using these three nodes to specify the arc.
1. **One way and three of its' nodes** selected:[[BR]]
 The arc is "fused" into the selected way between the three selected nodes using them to specifiy the arc.


If multiple ways share the nodes in 2 or 3, those ways are modified, too.

Currently the middle node is moved, making the nodes in the arc proportionally distributed.


The maximum angle between two points in the arc (ie. the "resolution") can be set with the preference key:
{{{
curves.circlearc.angle-separation
}}}
The default is 20.
