4.2.3 Offsetting an Open Profile and Updating the Table
R.OFF Normal offset of an open profile.
The R.OFF function is used for normal offset of a profile initially created in a table by
the P.BUILD function or a table with the same format, i.e. [Pa(7,Nb)].
After execution of the R.OFF function, the offset profile is contained in the same table
and the variable specifying the number of blocks is updated since intermediate blocks
may have been created (see Fig. 1).
Syntax
R.OFF [Pa(7,Nb)] / ±1 / R
R.OFF Normal offset of a profile.
Pa Table name.
7 Number of table entries.
Nb Name of the variable containing the number of blocks in
table Pa.
±1 Value = +1: right offset of the profile,
value = -1: left offset of the profile.
R Radius expressed in the same units as the dimensions.
Note
The R.OFF function must be the first word in a block.
The profile executed with the R.OFF function must be an open profile, i.e. the start
point of the profile must be different from the end point (see Fig. 2).
The R.OFF function can only operate on profiles contained in P.BUILD that do not
include alternating left and right offsets during execution.
