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

DECL/INTGR,I


DECL/CHAR,20,elnm


DECL/DOUBLE,xx,yy,zz


$$ Do Loop upon the three point above


DO/i,1,3


elnm=ASSIGN/CONCAT('poi_',STR(i))


$$ Third value from the FA(POI_X)


xx=OBTAIN/FA(@elnm),3


yy=OBTAIN/FA(@elnm),4


zz=OBTAIN/FA(@elnm),5


elnm=ASSIGN/CONCAT('newpoi_',STR(i))


F(@elnm)=FEAT/POINT,CART, xx,yy,zz, 0,0,0


FA(@elnm)=FEAT/POINT,CART, xx,yy,zz, 0,0,0

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
