`Y1`	Y coordinate on local 𝑥-axis. (Real)
`Z1`	Z coordinate on local 𝑥-axis. (Real)
`X2`	X coordinate on local 𝑥y-vector. (Real)
`Y2`	X coordinate on local 𝑥y-vector. (Real)
`Z2`	X coordinate on local 𝑥y-vector. (Real)
`Ox`	X coordinate of skew origin. (Real)	$[m]$

Comments

If OPTION is defined, XP1, YP1, ZP1, XP2, YP2, and ZP2 are expressed in the local coordinate system.
This keyword maps to /BOX/RECTA and /SKEW/FIX if the option LOCAL is defined.
