Use Positions in Expressions

The basic ways of defining a position are:

• Position attribute plus optional WRT. For example:

  POS OF /VESS1 WRT /* or P1 POS OF /CYL2

• Cartesian position. For example:

  N 45 W 20000 U 1000

• Cartesian position from an element. For example:

  N 1000 FROM /ATEST

• Cartesian position from a ppoint. For example:

  N 1000 FROM P1 OF /BOX2

• Cartesian position from an attribute. For example:

  N 1000 FROM POSS OF /SCTN1

• Any numeric value within a position may itself be an expression. For example, the following is a valid position expression:

  N (DESP[1] + 10) E

The Cartesian position may optionally be followed by WRT to specify the axis system. See WRT.
