== Arc tools ==
The tools described in this section have been designed to create the arcs required in some conditions. Such conditions can be different, for example distance or angle, parents' positions, etc.
===Arc - Radius and Angles (Shortcut Alt+A)===
{|
|[[File:Arc.svg|50x50px]]
|Used to create an arc at a distance from an axis node
|-
|
|Click on the axis node. Enter the radius (or a distance) formula from the axis. Enter the first angle and the second angle from the axis node. Angle values <code>'''0'''</code> & <code>'''360'''</code> will create a full circle.
|-
|
|
* Name: Name of the new arc
* Center point: Center point of the arc
* Radius: You can define a fixed radius or use formulas for adaptive / calculated values
* First Angle: You can define a fixed angle or use formulas for adaptive / calculated values
* Second Angle: You can define a fixed angle or use formulas for adaptive / calculated values
* Attributes: Specify the color, linetype and lineweight of the new node

|[[File:Arc intersect axis.svg|50x50px]]
|Used to place a node on an arc where an axis would intersect an arc
|-

{|
|[[File:Point of intersection arcs.svg|50x50px]]
|Used to create a node where at the intersection of two arcs
|-
|
|Select the first arc and then the second arc. A node will be created where they intersect. You may choose between the first or second point of intersection if there are two places where they intersect
|-
|
|
* Name: Name of the new node
* First arc: First selected arc
* Second arc: Second selected arc
* Take: First point (nearest to start point), Second point (nearest to end point)

=== Point - Intersect Circles (Shortcut Shift+I, Shift+C) ===
{|
|[[File:Point of intersection circles.svg|50x50px]]
|Used to create a node at the intersection of two circles
|-
|
|Select the node at the centre of the first circle and then the node at the centre of the second circle. Enter the diameters of both circles and select whether you want to take the first or second point
|-
|
|
* Name: Name of the new node
* Take: First point (nearest to start point), Second point (nearest to end point)
* Circle 1 - Center: First selected point
* Circle 1 - Radius: You can define a fixed radius or use formulas for adaptive / calculated values
* Circle 2 - Center: Second selected point
* Circle 2 - Radius: You can define a fixed radius or use formulas for adaptive / calculated values
