absolute WCS

Hi,

Is any body know what is the meaning of " absolute WCS"?  The NX help documentation  uses this term a lot. Is it the absolute coordinate system or the work coordiante system(WCS)?

Absolute WCS refers to 0,0,0 of the current WCS.  If the WCS is moved, the Absolute WCS moves with it.

 

This is different from the Absolute CSYS, which is always in the same location. (0,0,0)

Absolute WCS is referring to where the 0,0,0 origin of the model is located at as well as the data model orientation of the X,Y.Z vectors.  While there may be several CSYS's in a model, there is only one WCS at any one time and while that WCS may be located somewhere other than at absolute 0,0,0, when someone references something called the 'Absolute WCS' they are referring to this 0,0,0 location and X,Y,Z orientation as if it were a real object.

Sorry, I still don't understand. Does it mean that the absolute WCS means the absolute coordinate system of the part, including the origin(0,0,0) and the orientation there axis. 

The other questions is in the documentation screenshot I upload.  "X-Y plane of the displayed part" means the x-y plane in the absolute coordinated system or the xc-yc plane in the WCS of the displayed part?

Thank you.

Basically yes.

Since this involves that Mold Wizard, I can't be sure of exactly what the documentation was referring to in this instance.
