Creating an Offset Object CS

To create an Offset Object coordinate system (CS):

1. Select the working CS to use as the basis of the new Object CS.
2. Select the object to use as the basis of the new Object CS.
3. From the menu bar, click Modeler> Coordinate System> Create> Object> Offset or, from the Draw ribbon tab, click Object CS. (You do not have to access the Object CS drop-down menu because Offset CS by offset is the default type of Object CS):

   

4. Click a point on the selected object to locate the Origin for the new CS.
   • You can select any snap point on the object (depending on the current snapping mode options) to select origin of the Object CS. When you hover the mouse over a valid point, a coordinate system preview is shown.

     

   • The point must be on the selected object.
   • When you select the Origin point, the location is validated, and an appropriate message indicates when a point is invalid. Points where a CS preview appears are are always valid.
   • The X-axis {1,0,0}, Y-axis {0,1,0} and Z-axis {0,0,1} are parallel to the corresponding axes of the working CS that was active when you executed the Object CS command, but the Origin has been relocated.
   • The axis coordinates can be later edited through the docked Properties window or the Properties dialog box.
