- Right-click the coordinate system.This can be done either on the Markups pane or the frame in the 3D scene.
- Select Properties to open the Coordinate System dialog box.
- Select the Orientation tab.
- Click the appropriate radio button to select an axis around which the coordinate system will rotate.
- Choose one of the two methods shown below to set the orientation of the axis:
a. Select a point in the 3D scene:
- Pick 2 Points - Select two available points on the model. The axis direction will be toward the first point picked. Red dots designate available points on the model. Crosshairs indicate when the pointer is properly positioned over a point.
- Pick 3 Vertices (Normal Plane) - Pick three points to define a plane.
- Pick Normal on Surface - The axis will be oriented to the normal vector of the selected surface.
- Pick an Edge - Select an edge on the model. The edge is highlighted when the pointer is properly positioned for selection.
- Pick Another Coordinate System Axis - Click the axis of another coordinate system in the scene.
Click the desired location in the 3D scene.
Click OK to save the orientation and close the dialog box.
or
b. Enter vector values in the dialog box:
- From the Relative to drop-down menu, choose the coordinate system you would like the vector to be relative to
- Enter values in the x, y, and z fields next to the selected axis.
- Click Apply. If necessary, you can change the values and click Apply again.
- When you are satisfied with the results, click OK to save the orientation and close the dialog box.
