This menu groups the different possible actions on the drawing zone and on theirs objects.

There is a grid on the drawing zone, helping to create points with simple coordinates. This grid can be visible or hidden.
Centers the origin of the coordinate system in the drawing zone.
After activting this entry all objects in the drawing zone will be visible..
This entry redraws the drawing zone. One should use this when the display seems uncorrect.
This menu groups the objects that can be created in Dynamic Geometry.
This menu groups the numerous available manners to create a point.
An entry form opens, that allows to enter a formula for the each coordinate X and Y. Alternatively a complex formula can be entered.
After choosing the menu, just click at any place in the drawing zone.
1. A fixed point is always proposed. If the mouse is near a point on the grid, this point is proposed. If the mouse is near an object (line, circle, curve), a free point on this object is proposed also proposed. If it is near two objects whose intersection can be calculated, an intersection point is proposed. In other cases, a free point on the plan is proposed.
2. These points can also be created on the fly when creating other objects.
After choosing a segment or two points, this menu allows to create a point at the middle of this segment.
This menu allows to create a reported point related to another point of a certain distance, alongside of a certain vector. It's necessary to choose five points: the mentioned point, two points defining the direction of the transfer, and finally two points defining the distance.
This menu allows to create a reported point related to another point of a certain algebraic distance, alongside of a certain vector. It's necessary to choose three points: the first mentioned point, two points defining the vector direction; and enter an algebraic expression defining the distance.
This menu groups different and available manners to create a
straight line.
After choosing two points, this menu allows to create a line passing through these two points.
After choosing a point and a line (line, half-line, segment), this menu allows to create a line parallel to the chosen line and passing through the chosen point.
After choosing a point and a line (line, half-line, segment), this menu allows to create a line perpendicular to the chosen line, passing through the chosen point.
It is necessary that the derivative of the function defining the curve has been created by calculation in the Algebra tab. Then you can choose a point on the curve.
After choosing two points, this menu allows to create a half-line starting at the first point and passing through the second one.
This menu allows to import in the Window the graphic representation of a function of Casyopee.
This menu groups the different available manners to create a circle.
After choosing three points, this menu allows to create a circle whose the center is the first chosen point ans the radius is the distance between the second and the last chosen point.
After choosing two points, this menu allows to create a circle whose the center is the first chosen point and the radius is the first and the second chosen point.
Choose a point. Then an entry form opens, that allows to enter a formula for the radius.
This menu entry switches to the Geometrical Calculations Tab and opens the entry form.
For a regression other than linear, when a curve is plotted, Casyopee offers to create a geometrical calculation "sum of squared deviations," from a series of points to this curve (the differences is calculated "vertically"). Click thepoints in succession and then click the curve to complete. See onlinehelp.
