create an Axes object by double clicking on "Axes" in the Objectbox. from the Axes dialog you control its’ appearance. when Draw Axes is checked, you will see a red, a green, and a yellow line, aligned with the X, Y, and Z axes respectively. the axes lines intersect at the center of the Axes object, which defaults to the K-3D Origin. you can control the length of the axes lines using the Axis / Plane Size control.

to get additional help envisioning three-dimensional coordinates on your two-dimensional computer screen, you can also turn on any combination of three grids, using the Draw XY Plane, Draw YZ Plane, and Draw XZ Plane checkboxes. each of these draws a gray grid in the plane defined by its’ respective axes. the size of all of the grids is again controlled with the Axis / Plane Size control. the number of squares along each side of each grid is controlled by Grid Divisions.

you can move the center of the Axes object to any point in the K-3D world by entering coordinates in the Center XYZ controls. to change the coordinates interactively, make the Axes dialog the Active Tool and LMB Drag to change the coordinates in the two axes that aren’t active. hold down either control-key and LMB Drag to change the center coordinates along the current Active Axis.

you can rotate the Axes object to any orientation by entering angles in the Angles XYZ controls. to change the orientation interactively, LMB Drag with either shift-key held down to rotate the Axes object around the two axes that aren’t active. hold down either control-key and either shift-key to rotate the Axes object around the current Active Axis.
