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)

	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 0 & 360 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

Point - On Arc (Shortcut O, A)

	Used to place a node on an arc
	Click on the arc and enter the distance from the start of the arc where you’d like to place a node
	Name: Name of the new arc Arc: Selected arc Length: You can define a fixed radius or use formulas for adaptive / calculated values

Point - Intersect Arc and Axis (Shortcut A, X)

	Used to place a node on an arc where an axis would intersect an arc
	Click on the arc and then on an axis node, drag around in the general direction and click. You may now edit the angle or enter a formula to get the precise placement of the node
	Axis point: Start point of axis. It's the second point you selected Curve: Curve you selected first Name: Name of the new node 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

Point - Intersect Arcs (Shortcut I, A)

	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)

	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
	Important note:If no intersection could be calvculated, Seamly2d will show you an error message and place the nodes at 0, 0 X/Y position.

Point - Intersect Circle and Tangent (Shortcut C, T)

	Used to create a node where a line touches the circle
	Select the axis node and then the circle centre. Enter the radius of the circle
	Name: Name of the new node Take: First point (nearest to start point), Second point (nearest to end point) Center point: Second selected point Tangent point: First selected point Radius: You can define a fixed radius or use formulas for adaptive / calculated values

Point - Intersect Arc and Tangent (Shortcut A, T)

	Used to create a node on an arc where a line touches the arc
	Select the axis node and then the arc. You may choose between the first or second point of intersection
	Name: Name of the new node Tangent point: First selected point Arc: Selected arc Take: First point (nearest to start point), Second point (nearest to end point)
	Important note:If no intersection could be calvculated, Seamly2d will show you an error message

Arc - Radius and Length (Shortcut Alt+Shift+A)

	Used to create an arc where the arc-line is a given length
	Select the centre-node for the arc and then enter the radius, the angle at which you’d like the arc to begin and the length of the arc-line.
	Name: Name of the new node Center point: Center point of the arc. It's the first point you selected 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 Length: You can define a fixed length or use formulas for adaptive / calculated values Attributes: Specify the color, linetype and lineweight of the new node

Arc - Elliptical (Shortcut Alt+E)

	Used to create an elliptical arc
	Select the centre node for the ellipse and then enter first and second radiuses. Enter the angle to start and to end the ellipse and then the angle from which to start the rotation. Click on OK to complete
	Name: Name of the new node Center point: Center point of the elliptical arc. It's the first point you selected Radius1: You can define a fixed radius or use formulas for adaptive / calculated values Radius2: 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 Rotation 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
