The OBTAIN/ commandis used to get a value from a feature.
The parameter is chosen by using its position inside the definition statement.
It is important to consider the differences between F(label) and FA(label) or S(label) and SA(label).


Examples:
$$ Example of Obtain Command

F(POI_1)=FEAT/POINT,CART,1.111,2.222,3.333,0,0,1
F(POI_2)=FEAT/POINT,CART,4.444,5.555,6.666,0,0,1
F(POI_3)=FEAT/POINT,CART,7.777,8.888,9.999,0,0,1
FA(POI_1)=FEAT/POINT,CART,1.111,2.222,3.333,0,0,1
FA(POI_2)=FEAT/POINT,CART,4.444,5.555,6.666,0,0,1
FA(POI_3)=FEAT/POINT,CART,7.777,8.888,9.999,0,0,1

Use EVAL/ instead of OUTPUT/ to get the value of a tolerance without creating the output of it.
Examples:
$$ Example of the use of EVAL

DECL/DOUBLE,tol_value
T(TP)=TOL/POS,2D,1.0000

$$ Evaluation of the T(TP) in the PO1 feature without the output

EVAL/FA(PO1),TA(TP)
tol_value=OBTAIN/TA(TP),3
