KOMPAS-3D v23

Every model has an absolute coordinate system, and planes and axes defined by it. The names of coordinates axes and planes appear in the Design Tree immediately after a new model file is created.

The image of the absolute coordinate system of the model is displayed in the middle of the window in the form of three orthogonal segments of red, blue and green colors. The common origin of segments is the origin of the model coordinate system – a point with 0, 0, 0 coordinates.

Planes are conventionally displayed on the screen in the form of rectangles of red, blue and green colors lying within these planes. By default, rectangles are located so that their centers are aligned with the origin of the coordinates, such display lets you see placement of planes in space. Sometimes, to understand the location of the plane, it is necessary that the rectangle which symbolizes the plane was bigger (smaller) or located in another place of the plane. You can change the dimension and position of this rectangle by dragging its defining points (they appear when the plane is selected) with the mouse, or fit the rectangle dimension to the model dimension automatically (see the section Fitting the plane size to the model size).

The following actions can be performed with axes and planes in the absolute coordinate system:

•rename (see the section Names and icons of objects in the Tree),

•display the name in the graphic area (see the section Display of the object caption in the graphic area),

•enable/disable display in the graphic area (see the section Managing visibility of objects).

You cannot delete coordinate axes and planes of the absolute coordinate system from the model file.

The model orientation control is displayed in the lower left corner of the graphic area. It consists of three 3D arrows of red, green and blue colors, showing positive directions of the X, Y, Z axes of the absolute coordinate system. Use this control to change the model orientation, for example, by clicking the arrow or rotating in space. For details about methods of working with this control, see the section Orientation Management in the Graphic Area of the Model.

When using other methods to rotate the model, the element will rotate in the same way as the icon located in the origin of the absolute coordinate system, but unlike the latter, it cannot be shifted when the model is moved and cannot be disabled.
