To Create a Coordinate System
You can create coordinate systems in part or assembly mode. Use the following steps:
1. Select the placement references in the graphic window. A Live Toolbar and a dragger appear.

|
  appears on the Live Toolbar only if you select an edge or a vertex as a placement reference. |
2. Click
. An Options Toolbar opens. Expand the Options Toolbar to open a Floating Dashboard. A default coordinate system appears on the selected point on a surface or on the selected entity.
| If you select a surface as a placement reference, on the Home tab, click Csys to open the Options Toolbar. |
3. To change the origin, pull the circular dragger. Alternatively, select additional intersecting geometry. Hold down the CTRL key and select geometry types to add to the current selection.
4. To change the orientation of the first axis, click Axis 1 and select a reference entity in the graphics window. In the box next to Axis 1, select X, Y, or Z axis to define the coordinate system. Similarly, click Axis 2 and change the orientation of the second axis.
5. The Offset panel shows the offset references for the coordinate system. These references and the references selected in steps 1 and 2 set the position of the coordinate system. To change the offset references,
a. Click the down arrow below the Offset panel and,
b. In the References box, select the reference value you want to change and type a new value.
Alternatively, double-click the reference values in the graphics window and type a new value.
In the
Offset panel, click
Display reference dimensions to display the coordinate system offset dimensions.
| You can also press S on the keyboard to toggle the display of coordinate system offset dimensions. |
6. On the Options Toolbar, click
to toggle the display of the angular draggers. Angular handles appear in the graphics window.
Alternatively, in the Floating Dashboard, select the Rotation check box.
7. To reorient the coordinate system, pull the angular handles. Alternatively, double-click the angle value in the graphics window and type a new value.
8. Change the axis labels, if required.
9. Flip the axes by selecting an item from the lists. If you flip one of the axes, the other two adjust automatically.
10. Middle-click to complete the operation.
