Elementary point creation mode

Create a new independent point or change an existing point to an independant point

Point creation modes

• Create or select existing points as reference points then create the point at given position
• Ratios and angles are chosen during last step
• You can replace an already existing point at last step
• You can use ⌘ to force point position to rounded ratio/angle
• You can keep ⇧ pressed at last step to create a sequence of points based on the same references points

	Define a point moving on a line defined by two points
	Define a point by distance and angle
	Define a point by relative coordinates
	Define a point by distance and angle ratio
	Define a point on a bezier curve

Translated points creation modes

• Create or select existing points as reference points then create the points at given position
• Distance and angles are chosen during last step
• You can replace an already existing point at last step
• you can use ⌘ to force point position to rounded distance/angle
• you can keep ⇧ pressed at last step to create a sequence of points based on the same references points

	Create a point translated by a constant value
	Create a point on a line, distance from the first point is a constant value
	Create a point on the bisector, distance is a constant value
	Create a point on normal, distance is a constant value

Computed points creation modes

• Create or select existing points as reference point. The generated point is shown during last step.

	Define a point between two given points
	Define the reflection of a target point with respect to a center
	Define the symmetric of a target point with respect to a segment
	Define the orthogonal projection of a target point onto a segment
	Define the projection of a target along an arc
	Translated point by a vector defined by two points
	Intersection of two lines
	Report transformation on ref1/ref2 to pt1/pt2

Shapes, lines and curves creation modes

• Double click or right-click to finish the shape

	Draw surface delimited by a series of segments
	Draw a series of segments
	Draw surface delimited by a series of bezier curves

Circles creation modes

• Create or select existing points as reference point, the generated circle is shown during construction.

	Draw a circle by selecting its center and a point of the circle
	Draw a circle defined by it's diameter

Ellipses creation modes

• Create or select existing points as reference point, the generated ellipse is shown during construction.

	Draw the smallest Ellipse defined by this three points
	Draw an Ellipse inscribed in a parallelogram defined by its center and the middle of two sides
	Draw an Ellipse inscribed in a parallelogram defined by its axis and the middle of one side
	Draw an Ellipse given its two foci and a point on the ellipse

Squares creation modes

• Create or select existing points as reference point, the generated square is shown during construction.

	Draw a square by its center and a corner
	Draw a square by its diameter
	Draw a square by two corners of a side of the square
	Draw a square by two points on the axis of the square

Rectangles creation modes

• Create or select existing points as reference point, the generated rectangle is shown during construction.

	Draw a rectangle by its center and two points on sides
	Draw a rectangle by two points on a side and a point on the opposite side
	Draw a rectangle by two points on opposite sides and a third point
