For any operation, change the coordinate system and origin to adapt to origin shifts and NC machine availability.
Use SURFCAM's Edit Setup Information dialog to designate as a Machine Datum a CView that suits the orientation of an operation.
SURFCAM outputs the NC code for that operation as if the CView chosen for Machine Datum were Cview 1 or WORLD coordinates.
Example
The following drawing labels the CView
indicator "a." The CView is set
to 1 (Top view). The geometry at the upper
right (labeled "b") falls in a different orientation.

Create
a new CView to match the geometry at the upper
right, labeled "b." For this example, name the new CView
"dat1."

Create
a cutting operation on the geometry labeled "b."

Open
the Operations Manager, and right-click on the Setup
that contains the above operation. Select Edit Setup
Information.

Set
Machine Datum to the new CView
"dat1"
and click OK.

In
the Operations Manager, click the Post Button
to create the NC code.
The provided "DEMO Bridge Mill" SPost
outputs the following NC code. For this operation, "dat1"
adopts the World Coordinate origin.
