Moving On Top of or Under a Fixed Object

Model Reference Manual

Equipment and Primitives : Moving In Front of or Behind Items : Moving On Top of or Under a Fixed Object

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 centreline 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 Figure 7:27.: Moving above/below a fixed object).
MOVE ALONG E45D DISTANCE 3000 UNDER /BEAM	Moves the Current Element along E45D until its origin is 3000 vertically below /BEAM (see Figure 7:26.: Moving above/below a fixed object in a specified direction and Figure 7:27.: Moving above/below a fixed object).

Note:

ONTOP means above in owner co-ordinates regardless of original Current Element position. The DISTANCE is always measured vertically in owner co-ordinates.
