Creation of the coordinate system by the origin point and two leading vectors
Creating a new coordinate system in this way is activated by pressing the menu item on the coordinate systems panel.
The new coordinate system is defined by the origin point and two leading vectors, X and Y. The zero point must be assigned by moving the cursor in the graphic window to the desired point. If it is a valid point to be used as the origin of the coordinate system, it will be highlighted. The selection is confirmed by left-clicking on it:
After that, the direction of the X-axis must be specified by choosing a point on the screen through which the X-axis will pass and left-clicking the mouse:
Then, the process is repeated for the Y-axis:
Afterward, the newly created coordinate system becomes active:
At any time, the name of the coordinate system, its color, and its origin point can be changed.
