Keywords:
MOVE DISTANCE ONTOP UNDER
Description:
This command moves the Current Element until its origin is a specified distance above or below a fixed geometric object. This takes into account the shape of the referenced object but not that of the Current Element. It is therefore applicable to, say, placing the centerline of a vessel a certain distance above the top surface of a beam.

Example: |
|
|---|---|
|
MOVE D ONTO /BOX |
Moves the Current Element along a vertical line until its origin lies in the upper surface of /BOX (see ). |
|
MOVE ALONG X45D DISTANCE 3000 UNDER /BEAM |
Moves the Current Element along X45D until its origin is 3000 vertically below /BEAM (see and ). |
Note: ONTOP means above in owner co-ordinates regardless of original Current Element position. The DISTANCE is always measured vertically in owner co-ordinates.
